A Time Called You (2023) s01e10 Episode Script
Episode 10
I killed her.
She's at peace finally.
What do you mean, you killed her?
Nam Si-heon,
she's dead all because of me.
So you're telling me In-gyu killed her?
In-gyu would never do that, huh?
I know he's not a killer, okay?
And on top of that, he committed suicide?
That's not who he is. This is wrong.
After In-gyu stepped off that ledge,
I kept trying to figure out
where it went wrong.
My mind raced through every moment.
This all started
on the day Kwon Min-ju was found dead.
That's my theory.
Shouldn't we travel back in time
and find a way to change this?
To be honest, there was
a part of my heart that wanted to, uh…
to stop thinking about what happened…
and just continue on living my life
without them and only you Jun-hee.
And yet…
And yet you couldn't live with yourself
if you abandoned In-gyu.
If I were in your position,
I would've done the same thing.
If you could only go back,
you would try over and over again, because
whether you're Nam Si-heon or…
or you're Koo Yeon-jun,
that's the kind of person you are.
You knew by going on that plane that day
that you were going to die,
but you did it so you could see me again.
So now,
I need to do my part in all of this.
I will go back to the year 1998.
But once I'm there,
how do we stop all this?
Make sure Min-ju lives.
You have to keep her alive at all costs.
But when you wake up in Min-ju's body,
you need to be careful,
because Min-ju's murderer
will be watching every move you make.
Do whatever it takes on October the 13th.
Mmm.
I'll do whatever it takes.
To the year 1998.
A TIME CALLED YOU
I wanna ask you something.
What is it?
"Whenever your heart calls for me…"
What does it mean, huh?
"Whenever your heart calls for me,
I will go to you."
Give me your hand.
When I come back from the past,
I need you to promise me something.
Promise me when I wake,
you will be by my side.
Promise me.
I promise you.
Oh, Jun-hee.
Oh.
What's wrong?
Is everything okay?
Did you make it back from 1998 just now?
No.
When I woke up,
you weren't by my side, Si-heon.
I got scared, and thought
I dreamt all of last night.
I'm very real.
Do you feel better now?
Mmm.
Hey, so from now on,
don't ever leave my side again, okay?
Mmm.
-Didn't you promise that?
-Yes, I did promise that.
I will always be by your side.
Mmm.
So you're saying last night,
you couldn't time travel to the past
even with the cassette player
like you used to.
That's the first time
it hasn't worked, right?
I wonder why that is.
So, I've been doing
some thinking about all this.
If we compare each other's
trajectory every time
we traveled back and forth from the past
we might be able to find some clues.
I'm wondering if…
if there's a loophole in all this.
When you listen to this song
on this cassette,
you time travel and wake up in the body
of someone you resemble,
someone you're connected to
in the thread of time and space,
so something had to disrupt that, right?
So if there is a loophole, then maybe
we should look for what the cause is.
I wonder if there were already clues
Do you remember anything odd in the past
we're not thinking of right now?
Ah, there was one thing
that was pretty odd.
In a span of a few months,
only two people were murdered back then.
Byeon Da-hyeon and Kwon Min-ju.
If this person was killing two people
just a few months apart,
then they're a serial killer by nature
and wouldn't stop killing all together.
So why weren't there more killings?
It's strange, right?
I agree.
When I did my own investigation,
the trail went cold
out of the blue so suddenly.
Usually, serial killers
only stop killing if they're caught.
And they never caught Min-ju's killer,
so why has he been dormant all this time?
Something's not adding up.
What if after
the initial murders happened,
the killer was prevented
from committing more crimes
from some unknown event
we've yet to find out?
I'll go to our old high school
and see what I can find.
I believe whatever event
we are looking for
must have been documented
in the school archives.
Then I will research articles from 1998.
I wonder if we missed any events
that were important at the time
that we didn't know about.
Good to see you again.
Oh wow! It's been a while.
So you do know who I am.
Of course I know who you are.
You're Nam Si-heon.
Girls from other schools lined up
at the school gate just to see you.
You were so popular.
This is a real surprise.
Oh, oh, I'm sorry take a seat.
Here. Be careful.
Careful now.
I heard you were in a terrible accident.
So how are your legs doing now?
I've been walking a lot better
as time goes on.
How have you been? Everything good?
All is good. And soon it'll be retirement.
Anyhow, what can I do for you today?
I have something important to ask you.
Do you remember the student Kwon Min-ju?
She was in my class.
Yes, I do.
Did you ever notice anything, uh, peculiar
surrounding the time of her death?
Uh, that was a while back, huh?
Not really.
Any strange events,
whether another student got injured
or maybe one of the students
transferred suddenly?
Anything you can tell me,
no matter how trivial?
Um, well, I'm just wondering if anything
back then struck you as strange.
Well, there was that other murder,
but you already know.
Um, other than that, I can't recall
anything strange happening. Sorry.
Uh,
then, how about, uh,
the school newspaper back in those days?
Are there any copies in the archive?
I'd like to look through them
just in case.
Oh, well, yes, they should be, uh…
The archive is in the library.
1998 NOKSAN MURDER CASE
NOKSAN HIGH SCHOOL GIRLS
MURDERED MONTHS APAR
MURDER SUSPECT, JUNG, 18, ARRESTED
VICTIM, BYEON DA-HYEON (18)
VICTIM, KWON MIN-JU (18)
MURDER SUSPECT OF KWON MIN-JU
MR. JUNG (AGE 18)
Did you find anything yet?
Uh,
not yet.
Si-heon, what's this all about?
You don't think
your friend In-gyu did this.
You think he's innocent, don't you?
Yes.
Since he confessed to the crimes,
there wasn't much I could do.
But we all thought it was really strange.
None of us believed
that In-gyu would do that.
That leads me to the question
that you had asked me earlier today.
There is one thing I did find strange.
I remember there was this kid,
not in my class though.
At first, I was told he was admitted
to the hospital
because of a common health issue.
I just assumed
that's why he took a leave of absence.
It wasn't until later I found out
that that boy was put
in a psychiatric hospital for a while.
-Do you know when all of this happened?
-Oh, well, it was back in 1998.
It was right after the murders
of those two girls.
Since the whole school
was still very unsettled by
the deaths of those innocent girls,
I think they didn't want
any more scandals.
Do you remember who, uh… who that kid was?
Oh, sure, um, I was his teacher
the year before, so…
Give me a moment. It was…
What was his name?
Chu… No, wait.
It was Cheol or Chung.
Something like that, uh…
All right, where do you want this again?
You can put it up against the wall.
Jeez, I told you
I'd get it myself later on.
I know. Don't worry about it, though.
I had a lot of free time
on my hands today.
Oh, well, thank you. Some coffee, then?
-Okay, sure.
-Make yourself comfortable.
You're looking at some scary stuff.
What's this all about, huh?
NOKSAN HIGH SCHOOL GIRLS
MURDERED MONTHS APAR
VICTIM, BYEON DA-HYEON (18)
VICTIM, KWON MIN-JU (18)
Wow.
Hey, Jun-hee.
-Hmm?
-What's with all this?
Oh, that…
It's nothing. I was just curious is all.
This looks like a very old murder case.
Yeah.
You said you've been having
bad dreams quite often
because of your insomnia.
Isn't that right?
Doesn't reading this kind of thing
make it worse for you?
Uh…
Hey, Chan-yeong.
Do you remember the dream
I had told you about the other day?
Mm-hmm.
Well, I wasn't dreaming it at all.
You weren't?
I…
Yeon-jun and I met again recently.
STUDENT RECORDS
Where is he?
-See you tomorrow.
-Okay, have a good night.
Oh, here he is. This is the guy.
Look here.
Oh Chan-hui.
Hmm.
So you're telling me you traveled
through time back to the year 1998.
And the girl who wrote this diary
is named Kwon Min-ju,
and you woke up in her body somehow.
And everything that had happened to you
in that past timeline,
you're saying
that you actually experienced all of it.
Am I right so far?
Mmm.
And not only that, you met Yeon-jun
in the year 1998,
except that wasn't his name, right?
His name was Si-heon, yeah?
Mm-hmm.
Uh,
I have no clue
how any of this can be possible.
So how were you able
to travel back in time in the first place?
By using this.
I don't know how, but this cassette player
lets me travel in time.
I fell asleep listening
to Seo Ji-won's song on the bus,
and when I woke up, it was 1998.
Strangely… uh, Kwon Min-ju and I
shared the same body,
as well as Yeon-jun and Si-heon.
So somehow we're connected
in this thread of time.
Hmm.
So if someone in a different timeline
looks like you,
then you are somehow
connected across space and time.
So if this is true,
I can use this cassette player
to travel into someone else's body.
That's pretty crazy, Jun-hee.
I know it sounds crazy.
But it's our only theory.
I know it's hard to believe,
but it's the truth.
It's so unbelievable, and that's why
I thought it was a dream at first.
Hey, Jun-hee.
I mostly believe you.
You believe me?
Uh-huh.
But this Byeon Da-hyeon case…
Why are you so interested
in what happened to her?
Ah.
I think that
the culprit from that case
and the culprit who murdered Kwon Min-ju
might be the same person.
At least, that's what I think for now.
Wh… What?
Kwon Min-ju was killed
back in 1998, right?
At the time, a guy I know was arrested
because he confessed to the murder,
but he would never do something like that.
So my instinct tells me that the murderer
had to be someone else.
My belief is
the murderer in Da-hyeon's case is
the person who killed Min-ju as well.
Chan-yeong.
Huh?
That cup of coffee is sounding pretty good
right now. Can you make me one?
Uh, sure. Just give me a minute.
Mm-hmm.
Who's this?
Do you like this girl?
Hey, Chan-yeong, you can't
go through my drawers like that.
Give it back to me.
You really like her a lot, don't you?
No, I don't. It's just, uh…
She's similar to me.
She doesn't talk much.
She doesn't have any friends either.
So I'm interested in her, only a little.
Well, it sounds like you like her a lot.
If you like her, just save her.
And she'll be yours forever.
Save her? What do you mean?
Make her into a butterfly specimen.
Once you do that, she's always yours.
I love saving butterflies
for my collection.
They are so beautiful to see.
Have you ever preserved a butterfly
Why not try it? I think you'll enjoy it.
Uh…
Chan-yeong,
please don't talk like that again.
A person is not an insect, okay?
If you like someone, uh,
you have to cherish them.
I should cherish them?
Mmm. That's right.
And you must, uh, keep your friends safe
and never ever harm them.
Huh? That's no fun.
It sounds really boring.
Hey, don't you think her eyes
look just like our puppy, Happy.
Now I see it all.
So Min-ju and Da-hyeon were killed by
someone who went to their school.
YEON-JUN
SLIDE TO POWER OFF
The phone has been turned off.
You will be forwarded to voicemail.
After the tone--
Even though it's been a while,
I'm pretty sure that Oh Chan-hui
was an introverted and quiet kid.
SIBLINGS: OH CHAN-YEONG
Oh Chan-yeong?
Oh Chan-yeong?
Oh, it appears he had a younger brother.
If he was born in 1988,
he would've been only ten years old.
Hey, it's Si-heon.
I might've found out who killed Jun-hee.
He was a student at Noksan High School.
His name is Oh Chan-hui.
Yes.
It also explains why the crimes stopped
after Min-ju was killed.
He's been hospitalized for a while.
He's been locked up there since 1998.
No, she's not.
I'm on my way to her place right now.
In the meantime, I will forward you
Oh Chan-hui's records from the school.
All right.
Hey, Chan-yeong.
Hey, Chan-yeong.
Chan-yeong, are you there?
Ah.
Ah, I'm sorry.
You said you could time travel
with this cassette player.
I wanted to see for myself if it worked.
Ah, well, did it work?
Well, the song was very pretty.
But I slept all the way through it,
I guess.
Oh, right.
Jun-hee, I'm starving.
Some food would be nice.
Uh, sure. I have some fruit.
Uh, would you like that?
-Hey, Jun-hee.
-Hmm?
The Kwon Min-ju murder in 1998…
Did the real culprit
leave any clues behind?
Oh, so the first time
that Kwon Min-ju was attacked, uh,
the culprit was wearing a uniform
from Noksan High School.
I think he had to be a student there,
maybe one of Min-ju's classmates.
One of the male students, perhaps.
I see.
I know how all of this
must sound right now.
I should thank you
for going along with this.
Not at all.
I should be thanking you for helping me.
Don't be silly. I didn't do anything.
It's because of what you
told me earlier tonight.
Now I know exactly what happened to me
and my brother back then.
Did I mention
I used to live in Noksan when I was young?
Next time, don't get in my way, Jun-hee.
Hey.
Hey, Chan-hui, are you okay?
Hey.
Hey, wake up.
Hmm?
Uh, are… are you all right, Chan-hui?
Oh, taxi!
Taxi!
OH CHAN-HUI
Uh, are you okay?
-Yeah, don't worry. I'm absolutely fine.
-Oh…
Something terrible almost happened.
Um, do you wanna go to the hospital?
Are you hurt?
Not at all.
No need to be concerned.
How about yourself? Are you okay?
So, how come you're alone out here?
Uh,
uh, if you're not hurt, I'll be on my way
if that's all right with you.
So, uh, thank you so much.
It could be dangerous
for you to go by yourself.
Uh, who knows who else
might be out here this late at night.
I'll go with you, hmm?
Uh, there's no need to do that.
Hey, I just saved you.
So now I feel a responsibility
to protect you.
Uh, were you trying to head
somewhere important earlier?
Uh, at the intersection,
that's where my mom works.
I know a shortcut. Let me take you there.
You'll get there in no time.
Hmm.
Mm-hmm.
What?
Stop! Let go of me!
Why are you doing this? Help!
Somebody hel--
Let go!
Ah! Stop it!
Get away from me!
Get away!
Hey, Chan-yeong.
Chan-yeong, are you there?
You don't know how incredibly disappointed
I am that you're not Kwon Min-ju.
Hello, everyone.
Are you all ready to order?
-Oh, what are you doing here?
-What are you doing here?
Uh, what is this?
Who is she?
So, what would you like to order today?
Take a look.
Our female customers tend to like
the A and B set menus, typically.
And, uh, as for the guys…
At first, I was excited
because I thought you were Kwon Min-ju.
…with the risotto?
The moment I saw you
look at me, that's when I realized
you were not the Kwon Min-ju in the photo
that I had obsessed over
so many years ago.
You weren't afraid.
You didn't shrink back
like she would have.
I didn't feel that rush of excitement
when I saw you
like I did with her.
Hey, Jun-hee.
Jun-hee?
Jun-hee?!
Jun-hee?
Jun-hee?
Jun-hee!
Hello? Somebody's collapsed.
Apartment 805, 45 Yeoksam-dong.
Please hurry.
Jun-hee.
Jun-hee!
Koo Yeon-jun?
Oh Chan-yeong.
What are you doing here?
Y… you'd better talk.
Uh, um, I just…
Jun-hee was like this
before I even got here. I swear.
You came out that way.
Uh…
I heard the door and thought
the person came back,
so I hid in that room
because I was afraid.
Do you really expect me
to believe all that?
Tell me.
Do you know what he did?
Did you do this
because Jun-hee found out about it?
What are you talking about?
What does my brother have to do with this?
I swung by
because I was dropping off that chair.
Look, it's right there.
That's when I found her
on the ground unconscious.
Hey, Yeon-jun.
I'm the one who should be
really surprised right now, huh?
Do you know how shocked I was
when Jun-hee told me
you were still alive somehow?
Didn't you just say that…
she was already passed
out when you found her?
It's you.
It wasn't Oh Chan-hui who did it.
It was you that killed
Min-ju and Da-hyeon.
Wasn't it?
It was always you.
Everything that's happened
is all of your fault.
Why did you do it, huh?
Why did you kill Kwon Min-ju, huh?
You're right.
You're right it was me.
It wasn't my brother at all. But
everything he used to tell me back then…
I finally now know what he meant.
I'm positive I know what to do now.
Getting to time travel into the past,
into my brother's body,
that's just an added bonus.
Hey, Yeon-jun.
Just so you know,
this is all Jun-hee's fault.
'Cause of her, this came together.
I'm so grateful.
Mmm.
No, Chan-hui.
You were wrong.
WHAT WOULD NAM SI-HEON SAY
IF HE FOUND OUT I LIKE HIM?
Look what you've done.
You've damaged a good specimen.
It's all right.
I can fix this, huh?
I'll be here a while.
-Come on. Let's go. Hurry, In-gyu.
-Ah.
Let me give you a shower.
-Hey.
-All right. All right.
-You're dead meat.
-Not if you can't catch me!
Si-heon, come back.
Si-heon, come back to me, please.
Oh no. Why Si-heon?
Why?!
Please don't go.
What am I supposed to do?
I can't do this alone. I need you.
It wasn't supposed to end like this.
Oh, what will I do now?
Si-heon…
My Si-heon!
Oh, Si-heon…
Don't go, please.
Oh Chan-yeong.
We need to find Oh Chan-yeong.
He took the cassette player from me.
I need it back to save Si-heon.
I'm going to bring Si-heon back to life
no matter what.
This was captured on camera
after he committed the crime.
Has anyone
been able to find him yet?
We raided his studio apartment
a little bit later,
but we couldn't find him.
We're using the security cameras
to try and trace his whereabouts.
Now, those items he stole from you,
were they valuable?
Yes, it was a cassette player
and an old diary.
Those were the only two things
that disappeared from my things.
He must've had a good reason to take them.
But why those specific items?
They're not particularly valuable.
Maybe there's something
he really needs them for?
Chan-yeong?
Hey, Chan-yeong.
Last night, when Chan-yeong came over,
he fell asleep on my couch.
He was listening to the cassette player
when I had woken him up, so, uh…
What if he went back to 1998
without us knowing?
If that's the case,
whose body could he have used?
Is there someone in the past
that Chan-yeong looks like?
Yes! Oh Chan-hui.
Si-heon sent me a picture
of his brother last night.
Hmm.
No, she's not Kwon Min-ju after all.
Isn't that right, Jun-hee?
Oh, Chan-hui.
I'm back from school.
Wait as second.
That poor dog was whimpering for ages.
I thought they were having fun.
I didn't think he would have hurt him.
The strange thing is,
after Chan-yeong killed the dog,
he didn't even bat an eye, you know?
Honestly.
Did I really raise him to be like this?
Something's wrong with him. I know it.
And I'm frightened of him.
It's driving me crazy.
Can you talk to him?
So where is my brother right now?
Hey, Chan-yeong.
Are you awake?
Okay then.
It seems
that you're not really in the mood
to talk about our dog, Happy, right now.
In that case, how about I leave you alone?
Mom's angry at me for what I did.
Hey, am I going to be punished
for what I did?
So does that mean
you're angry with me too?
Not at all. Why would I?
You said I should… I should cherish them.
That's what you told me to do, right?
I know I did.
But I've actually, uh,
thought more about what I said.
I was wrong.
You shouldn't change yourself at all,
Chan-yeong.
You know how animals are our pets?
Well, maybe people are also
just like pets in a similar way.
-They're pets?
-Yes, they are.
I need you to know that
you're a very special person just like me.
See, normal people like our mom,
they just don't understand who we are.
We're special to this world.
I'm gonna tell you something important.
It's a cool secret.
So I'm actually from the future.
You know that?
You don't know
what I'm saying, do you? Hmm?
Someday, uh, you'll understand everything.
And when that time finally comes,
uh, you will know what I'm saying.
In the meantime,
you have to hide yourself for now
until the time is right, okay?
Hide myself for now?
Just remember
that the most important thing
is for you
to be able to blend in with everyone.
It's only for the time being, all right?
Do not let anyone know
how special you are, Chan-yeong.
Learn to mask yourself and just wait for
the right moment when opportunity knocks.
Soon, it'll be easy for you.
One day, you'll understand.
I'll be finding my own specimens
to collect very soon.
Wanna tag along this time?
Let's find a pet that we both can preserve
into a specimen together, okay?
SAEMMUL CONVALESCENT HOSPITAL
He has good days, and he has bad days.
Now, on a good day, he sometimes
speaks a few words here and there.
But when he's having a bad day,
it's all just gibberish.
He'll even have seizures.
Just a moment.
Hello, Mr. Oh Chan-hui.
My name is Han Jun-hee.
So, I'm here today
because I have something to ask you.
Do you remember
what happened back in 1998?
Specifically to one of your classmates?
Her name was Kwon Min-ju, and, uh, she was
a third year at Noksan High School
and was found murdered that year.
Do you remember anything?
Can you hear me?
This is really important, sir,
so please answer me
if you understand me.
Do you remember what happened to her?
Was it you or your younger brother?
I need to know who killed her, huh?
Just answer the question,
and I'll go, okay?
I can…
hear everything.
I was present the first time
that we all…
…caught a specimen.
I saw and heard everything.
I could do nothing but watch her.
I was just an audience member, hmm?
Do you remember when I told you
that I was going to collect a new specimen
and that you could tag along with me,
so we could do it together?
What do you think?
Isn't this specimen pretty?
Make sure you hold
the light right there, hmm?
Mmm? Be quiet or you will get hurt.
Now, if you listen carefully
to my instructions,
this will all be over soon. You got it?
Let her go.
Let her go.
It…
it wasn't me.
I didn't do it!
Let her go! Let her go, huh?
I wanted to help her, but I couldn't.
It wasn't you.
It was Oh Chan-yeong,
your younger brother.
He was the one
who killed her that night, not you.
It was all Oh Chan-yeong, wasn't it?
Am I right?
Kwon Min-ju?
You're alive?
How are you here?
I didn't do it. Min-ju!
I didn't do it!
It wasn't me!
I had no choice, okay?
Min-ju, I swear.
They forced me to do it, huh?
I never wanted to do anything like that.
I would never hurt you Min-ju.
-I'd never hurt Min-ju, okay?
-All right, Chan-hui.
-They made me do it, I swear.
-It's okay.
It's okay. It's okay.
Calm down. It's all right.
So now we know who it was.
Oh Chan-yeong killed her
and not Oh Chan-hui.
Oh Chan-hui was forced to watch
his brother kill my niece Kwon Min-ju.
"They." What did he mean by "they"?
Who else could've been there
other than his brother, do you think?
What is it?
It's because of what you told me
earlier tonight.
Now I know exactly what happened
to me and my brother back then.
When I was back in the past,
the murder hadn't happened yet.
Oh Chan-yeong had yet to travel back
into his brother's body.
It wasn't until I told him everything.
That's when Chan-yeong discovered
he could travel back in time.
Ah. What have I…
I'm the one
who told Chan-yeong everything.
Then, that means
Si-heon and Min-ju are dead
all because of me. Oh!
There deaths were not your fault.
You didn't kill them, okay?
You didn't murder anyone.
Oh Chan-yeong is
the real murderer here, Jun-hee.
We have to catch him.
We need to find him
to get the cassette player back.
That's the only way
we can save Min-ju and Si-heon.
Um, hello?
What?
Hey, you said you've caught
Oh Chan-yeong already?
Yes.
We have him in custody.
We found him in a motel today.
Sir, by chance, at the time of the arrest,
do you know if
he was listening to music
on a cassette player?
How did you know about that?
Well, it's mine,
and I want it back if that's okay.
Please give it to me. I need it now.
Uh, after forensics sends it back to us,
it shouldn't be a problem
to return it to you.
We'll have it for you soon, okay?
That being said, the tape player
isn't in good condition right now.
Oh Chan-yeong.
Oh Chan-yeong!
Ah!
Hey, don't let him go. Grab him!
Not yet. It's not time yet.
Why? Please let me go!
EVIDENCE NUMBER 23-01
-Hey, it was you all along!
-Whoa! Whoa! Whoa!
-Hold on.
-It was you from the very start, huh?
-You're the killer! You killed Si-heon!
-Hey, you can't be doing this.
-Bring Si-heon back!
-Stop it!
Why did you do it? Why? I need to know!
No, Han Jun-hee!
You've got things all mixed up.
You should've asked yourself
something first.
How have I, Han Jun-hee, caused the murder
of Kwon Min-ju in the past?
Did you ever think about that?
Hey, come on.
You still don't get it?
You were the one responsible
for Kwon Min-ju's death, you see?
It's all because of you she's dead.
She's at peace finally.
What do you mean, you killed her?
Nam Si-heon,
she's dead all because of me.
So you're telling me In-gyu killed her?
In-gyu would never do that, huh?
I know he's not a killer, okay?
And on top of that, he committed suicide?
That's not who he is. This is wrong.
After In-gyu stepped off that ledge,
I kept trying to figure out
where it went wrong.
My mind raced through every moment.
This all started
on the day Kwon Min-ju was found dead.
That's my theory.
Shouldn't we travel back in time
and find a way to change this?
To be honest, there was
a part of my heart that wanted to, uh…
to stop thinking about what happened…
and just continue on living my life
without them and only you Jun-hee.
And yet…
And yet you couldn't live with yourself
if you abandoned In-gyu.
If I were in your position,
I would've done the same thing.
If you could only go back,
you would try over and over again, because
whether you're Nam Si-heon or…
or you're Koo Yeon-jun,
that's the kind of person you are.
You knew by going on that plane that day
that you were going to die,
but you did it so you could see me again.
So now,
I need to do my part in all of this.
I will go back to the year 1998.
But once I'm there,
how do we stop all this?
Make sure Min-ju lives.
You have to keep her alive at all costs.
But when you wake up in Min-ju's body,
you need to be careful,
because Min-ju's murderer
will be watching every move you make.
Do whatever it takes on October the 13th.
Mmm.
I'll do whatever it takes.
To the year 1998.
A TIME CALLED YOU
I wanna ask you something.
What is it?
"Whenever your heart calls for me…"
What does it mean, huh?
"Whenever your heart calls for me,
I will go to you."
Give me your hand.
When I come back from the past,
I need you to promise me something.
Promise me when I wake,
you will be by my side.
Promise me.
I promise you.
Oh, Jun-hee.
Oh.
What's wrong?
Is everything okay?
Did you make it back from 1998 just now?
No.
When I woke up,
you weren't by my side, Si-heon.
I got scared, and thought
I dreamt all of last night.
I'm very real.
Do you feel better now?
Mmm.
Hey, so from now on,
don't ever leave my side again, okay?
Mmm.
-Didn't you promise that?
-Yes, I did promise that.
I will always be by your side.
Mmm.
So you're saying last night,
you couldn't time travel to the past
even with the cassette player
like you used to.
That's the first time
it hasn't worked, right?
I wonder why that is.
So, I've been doing
some thinking about all this.
If we compare each other's
trajectory every time
we traveled back and forth from the past
we might be able to find some clues.
I'm wondering if…
if there's a loophole in all this.
When you listen to this song
on this cassette,
you time travel and wake up in the body
of someone you resemble,
someone you're connected to
in the thread of time and space,
so something had to disrupt that, right?
So if there is a loophole, then maybe
we should look for what the cause is.
I wonder if there were already clues
Do you remember anything odd in the past
we're not thinking of right now?
Ah, there was one thing
that was pretty odd.
In a span of a few months,
only two people were murdered back then.
Byeon Da-hyeon and Kwon Min-ju.
If this person was killing two people
just a few months apart,
then they're a serial killer by nature
and wouldn't stop killing all together.
So why weren't there more killings?
It's strange, right?
I agree.
When I did my own investigation,
the trail went cold
out of the blue so suddenly.
Usually, serial killers
only stop killing if they're caught.
And they never caught Min-ju's killer,
so why has he been dormant all this time?
Something's not adding up.
What if after
the initial murders happened,
the killer was prevented
from committing more crimes
from some unknown event
we've yet to find out?
I'll go to our old high school
and see what I can find.
I believe whatever event
we are looking for
must have been documented
in the school archives.
Then I will research articles from 1998.
I wonder if we missed any events
that were important at the time
that we didn't know about.
Good to see you again.
Oh wow! It's been a while.
So you do know who I am.
Of course I know who you are.
You're Nam Si-heon.
Girls from other schools lined up
at the school gate just to see you.
You were so popular.
This is a real surprise.
Oh, oh, I'm sorry take a seat.
Here. Be careful.
Careful now.
I heard you were in a terrible accident.
So how are your legs doing now?
I've been walking a lot better
as time goes on.
How have you been? Everything good?
All is good. And soon it'll be retirement.
Anyhow, what can I do for you today?
I have something important to ask you.
Do you remember the student Kwon Min-ju?
She was in my class.
Yes, I do.
Did you ever notice anything, uh, peculiar
surrounding the time of her death?
Uh, that was a while back, huh?
Not really.
Any strange events,
whether another student got injured
or maybe one of the students
transferred suddenly?
Anything you can tell me,
no matter how trivial?
Um, well, I'm just wondering if anything
back then struck you as strange.
Well, there was that other murder,
but you already know.
Um, other than that, I can't recall
anything strange happening. Sorry.
Uh,
then, how about, uh,
the school newspaper back in those days?
Are there any copies in the archive?
I'd like to look through them
just in case.
Oh, well, yes, they should be, uh…
The archive is in the library.
1998 NOKSAN MURDER CASE
NOKSAN HIGH SCHOOL GIRLS
MURDERED MONTHS APAR
MURDER SUSPECT, JUNG, 18, ARRESTED
VICTIM, BYEON DA-HYEON (18)
VICTIM, KWON MIN-JU (18)
MURDER SUSPECT OF KWON MIN-JU
MR. JUNG (AGE 18)
Did you find anything yet?
Uh,
not yet.
Si-heon, what's this all about?
You don't think
your friend In-gyu did this.
You think he's innocent, don't you?
Yes.
Since he confessed to the crimes,
there wasn't much I could do.
But we all thought it was really strange.
None of us believed
that In-gyu would do that.
That leads me to the question
that you had asked me earlier today.
There is one thing I did find strange.
I remember there was this kid,
not in my class though.
At first, I was told he was admitted
to the hospital
because of a common health issue.
I just assumed
that's why he took a leave of absence.
It wasn't until later I found out
that that boy was put
in a psychiatric hospital for a while.
-Do you know when all of this happened?
-Oh, well, it was back in 1998.
It was right after the murders
of those two girls.
Since the whole school
was still very unsettled by
the deaths of those innocent girls,
I think they didn't want
any more scandals.
Do you remember who, uh… who that kid was?
Oh, sure, um, I was his teacher
the year before, so…
Give me a moment. It was…
What was his name?
Chu… No, wait.
It was Cheol or Chung.
Something like that, uh…
All right, where do you want this again?
You can put it up against the wall.
Jeez, I told you
I'd get it myself later on.
I know. Don't worry about it, though.
I had a lot of free time
on my hands today.
Oh, well, thank you. Some coffee, then?
-Okay, sure.
-Make yourself comfortable.
You're looking at some scary stuff.
What's this all about, huh?
NOKSAN HIGH SCHOOL GIRLS
MURDERED MONTHS APAR
VICTIM, BYEON DA-HYEON (18)
VICTIM, KWON MIN-JU (18)
Wow.
Hey, Jun-hee.
-Hmm?
-What's with all this?
Oh, that…
It's nothing. I was just curious is all.
This looks like a very old murder case.
Yeah.
You said you've been having
bad dreams quite often
because of your insomnia.
Isn't that right?
Doesn't reading this kind of thing
make it worse for you?
Uh…
Hey, Chan-yeong.
Do you remember the dream
I had told you about the other day?
Mm-hmm.
Well, I wasn't dreaming it at all.
You weren't?
I…
Yeon-jun and I met again recently.
STUDENT RECORDS
Where is he?
-See you tomorrow.
-Okay, have a good night.
Oh, here he is. This is the guy.
Look here.
Oh Chan-hui.
Hmm.
So you're telling me you traveled
through time back to the year 1998.
And the girl who wrote this diary
is named Kwon Min-ju,
and you woke up in her body somehow.
And everything that had happened to you
in that past timeline,
you're saying
that you actually experienced all of it.
Am I right so far?
Mmm.
And not only that, you met Yeon-jun
in the year 1998,
except that wasn't his name, right?
His name was Si-heon, yeah?
Mm-hmm.
Uh,
I have no clue
how any of this can be possible.
So how were you able
to travel back in time in the first place?
By using this.
I don't know how, but this cassette player
lets me travel in time.
I fell asleep listening
to Seo Ji-won's song on the bus,
and when I woke up, it was 1998.
Strangely… uh, Kwon Min-ju and I
shared the same body,
as well as Yeon-jun and Si-heon.
So somehow we're connected
in this thread of time.
Hmm.
So if someone in a different timeline
looks like you,
then you are somehow
connected across space and time.
So if this is true,
I can use this cassette player
to travel into someone else's body.
That's pretty crazy, Jun-hee.
I know it sounds crazy.
But it's our only theory.
I know it's hard to believe,
but it's the truth.
It's so unbelievable, and that's why
I thought it was a dream at first.
Hey, Jun-hee.
I mostly believe you.
You believe me?
Uh-huh.
But this Byeon Da-hyeon case…
Why are you so interested
in what happened to her?
Ah.
I think that
the culprit from that case
and the culprit who murdered Kwon Min-ju
might be the same person.
At least, that's what I think for now.
Wh… What?
Kwon Min-ju was killed
back in 1998, right?
At the time, a guy I know was arrested
because he confessed to the murder,
but he would never do something like that.
So my instinct tells me that the murderer
had to be someone else.
My belief is
the murderer in Da-hyeon's case is
the person who killed Min-ju as well.
Chan-yeong.
Huh?
That cup of coffee is sounding pretty good
right now. Can you make me one?
Uh, sure. Just give me a minute.
Mm-hmm.
Who's this?
Do you like this girl?
Hey, Chan-yeong, you can't
go through my drawers like that.
Give it back to me.
You really like her a lot, don't you?
No, I don't. It's just, uh…
She's similar to me.
She doesn't talk much.
She doesn't have any friends either.
So I'm interested in her, only a little.
Well, it sounds like you like her a lot.
If you like her, just save her.
And she'll be yours forever.
Save her? What do you mean?
Make her into a butterfly specimen.
Once you do that, she's always yours.
I love saving butterflies
for my collection.
They are so beautiful to see.
Have you ever preserved a butterfly
Why not try it? I think you'll enjoy it.
Uh…
Chan-yeong,
please don't talk like that again.
A person is not an insect, okay?
If you like someone, uh,
you have to cherish them.
I should cherish them?
Mmm. That's right.
And you must, uh, keep your friends safe
and never ever harm them.
Huh? That's no fun.
It sounds really boring.
Hey, don't you think her eyes
look just like our puppy, Happy.
Now I see it all.
So Min-ju and Da-hyeon were killed by
someone who went to their school.
YEON-JUN
SLIDE TO POWER OFF
The phone has been turned off.
You will be forwarded to voicemail.
After the tone--
Even though it's been a while,
I'm pretty sure that Oh Chan-hui
was an introverted and quiet kid.
SIBLINGS: OH CHAN-YEONG
Oh Chan-yeong?
Oh Chan-yeong?
Oh, it appears he had a younger brother.
If he was born in 1988,
he would've been only ten years old.
Hey, it's Si-heon.
I might've found out who killed Jun-hee.
He was a student at Noksan High School.
His name is Oh Chan-hui.
Yes.
It also explains why the crimes stopped
after Min-ju was killed.
He's been hospitalized for a while.
He's been locked up there since 1998.
No, she's not.
I'm on my way to her place right now.
In the meantime, I will forward you
Oh Chan-hui's records from the school.
All right.
Hey, Chan-yeong.
Hey, Chan-yeong.
Chan-yeong, are you there?
Ah.
Ah, I'm sorry.
You said you could time travel
with this cassette player.
I wanted to see for myself if it worked.
Ah, well, did it work?
Well, the song was very pretty.
But I slept all the way through it,
I guess.
Oh, right.
Jun-hee, I'm starving.
Some food would be nice.
Uh, sure. I have some fruit.
Uh, would you like that?
-Hey, Jun-hee.
-Hmm?
The Kwon Min-ju murder in 1998…
Did the real culprit
leave any clues behind?
Oh, so the first time
that Kwon Min-ju was attacked, uh,
the culprit was wearing a uniform
from Noksan High School.
I think he had to be a student there,
maybe one of Min-ju's classmates.
One of the male students, perhaps.
I see.
I know how all of this
must sound right now.
I should thank you
for going along with this.
Not at all.
I should be thanking you for helping me.
Don't be silly. I didn't do anything.
It's because of what you
told me earlier tonight.
Now I know exactly what happened to me
and my brother back then.
Did I mention
I used to live in Noksan when I was young?
Next time, don't get in my way, Jun-hee.
Hey.
Hey, Chan-hui, are you okay?
Hey.
Hey, wake up.
Hmm?
Uh, are… are you all right, Chan-hui?
Oh, taxi!
Taxi!
OH CHAN-HUI
Uh, are you okay?
-Yeah, don't worry. I'm absolutely fine.
-Oh…
Something terrible almost happened.
Um, do you wanna go to the hospital?
Are you hurt?
Not at all.
No need to be concerned.
How about yourself? Are you okay?
So, how come you're alone out here?
Uh,
uh, if you're not hurt, I'll be on my way
if that's all right with you.
So, uh, thank you so much.
It could be dangerous
for you to go by yourself.
Uh, who knows who else
might be out here this late at night.
I'll go with you, hmm?
Uh, there's no need to do that.
Hey, I just saved you.
So now I feel a responsibility
to protect you.
Uh, were you trying to head
somewhere important earlier?
Uh, at the intersection,
that's where my mom works.
I know a shortcut. Let me take you there.
You'll get there in no time.
Hmm.
Mm-hmm.
What?
Stop! Let go of me!
Why are you doing this? Help!
Somebody hel--
Let go!
Ah! Stop it!
Get away from me!
Get away!
Hey, Chan-yeong.
Chan-yeong, are you there?
You don't know how incredibly disappointed
I am that you're not Kwon Min-ju.
Hello, everyone.
Are you all ready to order?
-Oh, what are you doing here?
-What are you doing here?
Uh, what is this?
Who is she?
So, what would you like to order today?
Take a look.
Our female customers tend to like
the A and B set menus, typically.
And, uh, as for the guys…
At first, I was excited
because I thought you were Kwon Min-ju.
…with the risotto?
The moment I saw you
look at me, that's when I realized
you were not the Kwon Min-ju in the photo
that I had obsessed over
so many years ago.
You weren't afraid.
You didn't shrink back
like she would have.
I didn't feel that rush of excitement
when I saw you
like I did with her.
Hey, Jun-hee.
Jun-hee?
Jun-hee?!
Jun-hee?
Jun-hee?
Jun-hee!
Hello? Somebody's collapsed.
Apartment 805, 45 Yeoksam-dong.
Please hurry.
Jun-hee.
Jun-hee!
Koo Yeon-jun?
Oh Chan-yeong.
What are you doing here?
Y… you'd better talk.
Uh, um, I just…
Jun-hee was like this
before I even got here. I swear.
You came out that way.
Uh…
I heard the door and thought
the person came back,
so I hid in that room
because I was afraid.
Do you really expect me
to believe all that?
Tell me.
Do you know what he did?
Did you do this
because Jun-hee found out about it?
What are you talking about?
What does my brother have to do with this?
I swung by
because I was dropping off that chair.
Look, it's right there.
That's when I found her
on the ground unconscious.
Hey, Yeon-jun.
I'm the one who should be
really surprised right now, huh?
Do you know how shocked I was
when Jun-hee told me
you were still alive somehow?
Didn't you just say that…
she was already passed
out when you found her?
It's you.
It wasn't Oh Chan-hui who did it.
It was you that killed
Min-ju and Da-hyeon.
Wasn't it?
It was always you.
Everything that's happened
is all of your fault.
Why did you do it, huh?
Why did you kill Kwon Min-ju, huh?
You're right.
You're right it was me.
It wasn't my brother at all. But
everything he used to tell me back then…
I finally now know what he meant.
I'm positive I know what to do now.
Getting to time travel into the past,
into my brother's body,
that's just an added bonus.
Hey, Yeon-jun.
Just so you know,
this is all Jun-hee's fault.
'Cause of her, this came together.
I'm so grateful.
Mmm.
No, Chan-hui.
You were wrong.
WHAT WOULD NAM SI-HEON SAY
IF HE FOUND OUT I LIKE HIM?
Look what you've done.
You've damaged a good specimen.
It's all right.
I can fix this, huh?
I'll be here a while.
-Come on. Let's go. Hurry, In-gyu.
-Ah.
Let me give you a shower.
-Hey.
-All right. All right.
-You're dead meat.
-Not if you can't catch me!
Si-heon, come back.
Si-heon, come back to me, please.
Oh no. Why Si-heon?
Why?!
Please don't go.
What am I supposed to do?
I can't do this alone. I need you.
It wasn't supposed to end like this.
Oh, what will I do now?
Si-heon…
My Si-heon!
Oh, Si-heon…
Don't go, please.
Oh Chan-yeong.
We need to find Oh Chan-yeong.
He took the cassette player from me.
I need it back to save Si-heon.
I'm going to bring Si-heon back to life
no matter what.
This was captured on camera
after he committed the crime.
Has anyone
been able to find him yet?
We raided his studio apartment
a little bit later,
but we couldn't find him.
We're using the security cameras
to try and trace his whereabouts.
Now, those items he stole from you,
were they valuable?
Yes, it was a cassette player
and an old diary.
Those were the only two things
that disappeared from my things.
He must've had a good reason to take them.
But why those specific items?
They're not particularly valuable.
Maybe there's something
he really needs them for?
Chan-yeong?
Hey, Chan-yeong.
Last night, when Chan-yeong came over,
he fell asleep on my couch.
He was listening to the cassette player
when I had woken him up, so, uh…
What if he went back to 1998
without us knowing?
If that's the case,
whose body could he have used?
Is there someone in the past
that Chan-yeong looks like?
Yes! Oh Chan-hui.
Si-heon sent me a picture
of his brother last night.
Hmm.
No, she's not Kwon Min-ju after all.
Isn't that right, Jun-hee?
Oh, Chan-hui.
I'm back from school.
Wait as second.
That poor dog was whimpering for ages.
I thought they were having fun.
I didn't think he would have hurt him.
The strange thing is,
after Chan-yeong killed the dog,
he didn't even bat an eye, you know?
Honestly.
Did I really raise him to be like this?
Something's wrong with him. I know it.
And I'm frightened of him.
It's driving me crazy.
Can you talk to him?
So where is my brother right now?
Hey, Chan-yeong.
Are you awake?
Okay then.
It seems
that you're not really in the mood
to talk about our dog, Happy, right now.
In that case, how about I leave you alone?
Mom's angry at me for what I did.
Hey, am I going to be punished
for what I did?
So does that mean
you're angry with me too?
Not at all. Why would I?
You said I should… I should cherish them.
That's what you told me to do, right?
I know I did.
But I've actually, uh,
thought more about what I said.
I was wrong.
You shouldn't change yourself at all,
Chan-yeong.
You know how animals are our pets?
Well, maybe people are also
just like pets in a similar way.
-They're pets?
-Yes, they are.
I need you to know that
you're a very special person just like me.
See, normal people like our mom,
they just don't understand who we are.
We're special to this world.
I'm gonna tell you something important.
It's a cool secret.
So I'm actually from the future.
You know that?
You don't know
what I'm saying, do you? Hmm?
Someday, uh, you'll understand everything.
And when that time finally comes,
uh, you will know what I'm saying.
In the meantime,
you have to hide yourself for now
until the time is right, okay?
Hide myself for now?
Just remember
that the most important thing
is for you
to be able to blend in with everyone.
It's only for the time being, all right?
Do not let anyone know
how special you are, Chan-yeong.
Learn to mask yourself and just wait for
the right moment when opportunity knocks.
Soon, it'll be easy for you.
One day, you'll understand.
I'll be finding my own specimens
to collect very soon.
Wanna tag along this time?
Let's find a pet that we both can preserve
into a specimen together, okay?
SAEMMUL CONVALESCENT HOSPITAL
He has good days, and he has bad days.
Now, on a good day, he sometimes
speaks a few words here and there.
But when he's having a bad day,
it's all just gibberish.
He'll even have seizures.
Just a moment.
Hello, Mr. Oh Chan-hui.
My name is Han Jun-hee.
So, I'm here today
because I have something to ask you.
Do you remember
what happened back in 1998?
Specifically to one of your classmates?
Her name was Kwon Min-ju, and, uh, she was
a third year at Noksan High School
and was found murdered that year.
Do you remember anything?
Can you hear me?
This is really important, sir,
so please answer me
if you understand me.
Do you remember what happened to her?
Was it you or your younger brother?
I need to know who killed her, huh?
Just answer the question,
and I'll go, okay?
I can…
hear everything.
I was present the first time
that we all…
…caught a specimen.
I saw and heard everything.
I could do nothing but watch her.
I was just an audience member, hmm?
Do you remember when I told you
that I was going to collect a new specimen
and that you could tag along with me,
so we could do it together?
What do you think?
Isn't this specimen pretty?
Make sure you hold
the light right there, hmm?
Mmm? Be quiet or you will get hurt.
Now, if you listen carefully
to my instructions,
this will all be over soon. You got it?
Let her go.
Let her go.
It…
it wasn't me.
I didn't do it!
Let her go! Let her go, huh?
I wanted to help her, but I couldn't.
It wasn't you.
It was Oh Chan-yeong,
your younger brother.
He was the one
who killed her that night, not you.
It was all Oh Chan-yeong, wasn't it?
Am I right?
Kwon Min-ju?
You're alive?
How are you here?
I didn't do it. Min-ju!
I didn't do it!
It wasn't me!
I had no choice, okay?
Min-ju, I swear.
They forced me to do it, huh?
I never wanted to do anything like that.
I would never hurt you Min-ju.
-I'd never hurt Min-ju, okay?
-All right, Chan-hui.
-They made me do it, I swear.
-It's okay.
It's okay. It's okay.
Calm down. It's all right.
So now we know who it was.
Oh Chan-yeong killed her
and not Oh Chan-hui.
Oh Chan-hui was forced to watch
his brother kill my niece Kwon Min-ju.
"They." What did he mean by "they"?
Who else could've been there
other than his brother, do you think?
What is it?
It's because of what you told me
earlier tonight.
Now I know exactly what happened
to me and my brother back then.
When I was back in the past,
the murder hadn't happened yet.
Oh Chan-yeong had yet to travel back
into his brother's body.
It wasn't until I told him everything.
That's when Chan-yeong discovered
he could travel back in time.
Ah. What have I…
I'm the one
who told Chan-yeong everything.
Then, that means
Si-heon and Min-ju are dead
all because of me. Oh!
There deaths were not your fault.
You didn't kill them, okay?
You didn't murder anyone.
Oh Chan-yeong is
the real murderer here, Jun-hee.
We have to catch him.
We need to find him
to get the cassette player back.
That's the only way
we can save Min-ju and Si-heon.
Um, hello?
What?
Hey, you said you've caught
Oh Chan-yeong already?
Yes.
We have him in custody.
We found him in a motel today.
Sir, by chance, at the time of the arrest,
do you know if
he was listening to music
on a cassette player?
How did you know about that?
Well, it's mine,
and I want it back if that's okay.
Please give it to me. I need it now.
Uh, after forensics sends it back to us,
it shouldn't be a problem
to return it to you.
We'll have it for you soon, okay?
That being said, the tape player
isn't in good condition right now.
Oh Chan-yeong.
Oh Chan-yeong!
Ah!
Hey, don't let him go. Grab him!
Not yet. It's not time yet.
Why? Please let me go!
EVIDENCE NUMBER 23-01
-Hey, it was you all along!
-Whoa! Whoa! Whoa!
-Hold on.
-It was you from the very start, huh?
-You're the killer! You killed Si-heon!
-Hey, you can't be doing this.
-Bring Si-heon back!
-Stop it!
Why did you do it? Why? I need to know!
No, Han Jun-hee!
You've got things all mixed up.
You should've asked yourself
something first.
How have I, Han Jun-hee, caused the murder
of Kwon Min-ju in the past?
Did you ever think about that?
Hey, come on.
You still don't get it?
You were the one responsible
for Kwon Min-ju's death, you see?
It's all because of you she's dead.
