My Stepmom's Daughter Is My Ex (2022) s01e01 Episode Script
The Former Couple Refuses to Say... 'It's things like this...!'
1
Where are you going, Mizuto-kun?
Right back at you. Where are
you going, Yume-san?
Oh? I thought you two were headed out.
We were just about to leave.
For that bookstore
on Karasuma Street, by chance?
A little bird told me you like to read!
So you two must be headed to the same place.
Yume only ever goes to the
bookstore or the library, after all.
M-Mom, please!
I trust you'll take care of her, Mizuto-kun.
S-Sure thing
All righty then. You two get along, okay?
Take care!
Why did you say yes?
You heard her.
She didn't give me much choice.
Why should I have to tag along
with someone like you?
Whatever. I don't want you
tagging along, either.
I always hated how passive you are.
Stupid geek!
And I always hated how selfish you are.
Stupid nerd!
Irido
That curry was so good!
The Former Couple Refuses to Say
"It's things like this!"
I'm glad you liked it.
Thanks for the meal.
Of course!
Thanks for the meal.
I'm so glad they seem to be getting along.
You're telling me.
To suddenly get a housemate
of the opposite sex at that age
I guess that sort of thing
doesn't matter much nowadays.
Well, looks like I was worried over nothing!
Families come in all shapes
and sizes these days.
Just because they're stepsiblings
doesn't mean they can't get along.
Here you go, dear.
You get it, don't you?
Why thank you, Yuni-san.
Get what?
We mustn't do anything to upset them.
I know that.
I'll take what happened
between us to my grave.
Excellent.
Look who's all high and mighty.
Since when were you this bossy?
If I wasn't like this before,
then it's certainly your fault
that I'm like this now.
Huh?
Got a problem?
Apparently their daughter's
gonna start living on her own.
Yeah?
Yeah, and I heard
Beyond All Limits
I've completely reached my limit.
Something's Wrong
Is something wrong?
How much longer do you plan on calling
me by my given name like it's nothing?
You're using my given name too.
That's better than you using mine.
Not much we can do now
that we share a family name.
What would you suggest I call you?
That's obvious, isn't it? It's perfect.
What is?
"Onee-chan."
Huh?
We're siblings now, so addressing me
as your older sister makes perfect sense, no?
Hold it, hold it, hold it.
You're the older sibling?
Gimme a break. It's the other way around.
I'm the older sibling here.
Let me put this simply, since your
brain cells seem to be off duty right now.
Listen well.
Our society considers the
firstborn child to be the eldest.
That's premise number one.
I was born before you.
That's premise number two.
Therefore, I am the older sibling.
It's the logical conclusion. You follow?
But if memory serves, weren't we
both born on November 3rd?
So we're the same age, correct?
By the day, perhaps,
but that's not everything.
You must also consider the time of birth.
Time of birth?
I asked Mineaki-san in order
to settle the matter.
I was born at 11:04 AM,
while you were born at 11:34 AM.
In other words, I was born
thirty minutes earlier.
You with me?
Didn't Japan used to consider the firstborn
twin to be younger in ancient times?
But we're not twins.
We're not even siblings in the first place.
Hey, wait a second
We consider the firstborn
to be the eldest now anyway.
Just go along with it, would you?
Thought you could fool me?
Whatever. I'm the older sibling. QED.
Case dismissed.
I'm going to be the older sibling.
The thought of being your
little sister creeps me out!
Same here!
I'd take anything over
being your little brother!
Wait, hang on.
What?
Glaring at each other won't get us anywhere.
At times like this, any reasonable person
would settle things with a game.
Irritating choice of words, but you're right.
In that case
How about this?
We've both accepted the fact that
we'll have to hide our previous relationship
and act like any normal stepsiblings would.
We've both been doing well so far,
but either one of us may yet slip up
and do something out of line, no?
So whoever screws up first loses.
So whoever first acts in a manner
unnatural for a stepsibling
Little Brother
becomes the younger brother or sister?
Little Sister
Little Brother
Little Sister
The sense of competition
engendered by such a rule
should also help inspire us
to better hide our past.
So do these rules apply even
when our parents aren't around?
Of course.
Also, that's per slip-up.
The winner gets to decide how the
younger shows it every time.
I guess there'd be no point
if it was sudden death.
Okay, let's go with that.
Then
The game starts now.
Wai—What are you doing?!
Oh, what's wrong?
Isn't this normal sibling behavior?
I get it now
It seems he's finally realized the true
nature of the rules I laid out..
Even if it's an obvious provocation,
I'm not allowed to show
irritation over any action
that would be considered
normal among siblings.
Such a reaction would fall into the
category of "unnatural for a stepsibling."
In other words
This was just a ploy to get under my skin!
Stupid girl She proposed
those rules just for that?!
She's twisted!
This is bad.
My own personal Pandora's box is right there!
That drawer contains things
I can't let anyone see!
What do I do? What do I do?
What do I do? What do I do?!
Forgive me
I can't bear to fight with you any longer.
If I've upset you, I apologize.
I'll even get out of your sight.
So please
Can we put this behind us?
Irido-kun
Yup, you're out!
Siblings don't call each
other by their last names.
B-But you're out too, aren't you?
Wanting to bury the hatchet is completely
normal for siblings, don't you think?
Now then, since this is the first round,
let's keep it simple.
Just say it.
H-How should I say it?
However you'd like.
O-Onii-chan
Well, you've learned your lesson.
Now you know not to mess with me.
You may fancy yourself a
hardcore mystery fan,
but you and I simply aren't
on the same level up here.
You never
used to be this mean to me back then!
There, there.
You're right. I'm sorry.
Onee
Nee-san.
Th-This is the part of you I
I always hated how you flip-flop like that!
Stupid Onii-chan!
You both look wonderful!

We're walking to school separately

That goes without saying.
Anyway, shouldn't you be more
focused on making friends?
This is your high school debut.
My high school debut?
I'm the only one in the entire school
who knows you used to be a total nerd.
It's the perfect time to reinvent yourself.
Don't you worry, Mizuto-kun.
I have a secret weapon up my sleeve.
Rakuro High School Entrance Ceremony
Now for the opening address.
Rakuro Private High School's
entrance ceremony is about to begin.
You were so cool back there, Irido-san!
You didn't seem nervous at all!
That's not true. I was a
nervous wreck on the inside.
Really?!
Yup.
You little
Rakuro High School Entrance Ceremony
And now a word from
our first-year representative,
Irido Yume-san.
Coming!
Lured by the warmth of the spring breeze,
the cherry blossoms start
to bloom on this
You must have aced the entrance exam
if they made you the student rep, right?
How much did you study?
Not much is what I'd like to say,
but honestly, I studied day and night.
I still don't feel like
I'm truly free from it.
How on earth does this girl
have better grades than me?!
You little
Attendance
Take your seats, everyone.
Orientation
I'm gonna start orientation.
Irido!
What junior high did you go to?
Nagimi Middle. Why?
Huh. You play video games?
No, not really.
Gotcha.
Wh-What's going on?
Just thought it might be fun
to play together if you did.
Why are people flocking to me now?
Um
So anyway
Is it true you and Irido-san are stepsiblings?
They really caught me off guard with that.
But that girl
Did she really tell everyone
we're stepsiblings?
Even if they would've
figured it out anyway
You know that Irido-san girl?
She's a real cutie, isn't she?
Yeah.
A cutie? Give me a break.
I'd go to the optometrist and get
my eyes checked if I were you.
It was love at first sight.
So your plan is to get close
with the younger brother, right?
If I went to her directly,
she'd just shoot me down.
So she told people I'm younger, huh?
That girl
It'll be smooth sailing if I can get
to her through him, y'know?
But her brother was such a killjoy.
Maybe he just thought
you were annoying?
Whoa, harsh!
I see what's happening.
So they mean to use me as a
stepping stone to get to her, huh?
Irido
What do you want?
Aren't you upset?
They're looking down on you.
You mean those guys that swarmed me?
They don't have the guts
to speak to me directly,
but they assume you're a pushover,
so they're using you to get to me.
I hate people like that.
Don't let it bother you.
They're not worth the time.
But then you'll—
What about me?
Nothing
I see.
My Stepmom's Daughter is my Ex
What is she doing?
Hey
What is it?
Didn't we agree to walk
to school separately?
What on earth is she thinking?
Rakuro Private High School
Hey! It's Mizuto-kun.
Let's hang out.
Oh?
Sorry, you two.
Mizuto and I are talking right now,
so would you mind not getting in our way?
Irido-san?
Y-You two aren't—
You are brother and sister, right?
Indeed.
Sorry for having a brother complex.
What was that?
Just now
Irido
I'm gonna buy it and come home
Mom
Today
Sorry, Yume. I think I'm gonna be home late today. It seems like
Mineaki-san is gonna be late too, so tell Mizuto-kun for me, will you?
Looks like Mom and Mineaki-san
will be home late tonight.
Should I make something to eat, then?
You can cook?
A little.
It was just me and my dad, after all.
And you
You're terrible at it, right?
Well, what are you gonna make?
I'll see what's in the fridge
and decide from there.
Okay, what do we have?
Eggs and fish That'll need prepping.
What else?
Breasts, huh?
B-Breasts?!
Hmm?
Got something against chicken breast?
Oh No, not really.
Hey
Hmm? What is it?
About this morning
The sensation on your arm
from when I hugged you
You should wipe it from your memory!
Huh?
Oh, yeah, I'd already forgotten about that.
I see!
Infuriating! So infuriating!
Absolutely, truly, and utterly infuriating!
You'd already forgotten, huh?
Are you trying to say mine are forgettable?
There must be some way
to break through his indifference
Japan Sinks
I'm out now.
All right! That worked better than I expected.
I—You—What gives?!
I'm in my own home, you know?
It's not that big of a deal.
No, but I'm here, so
Oh?
So what if my brother's here?
Or, don't tell me
Mizuto-kun, are you the kind of bad boy
who'd sneak a peek at his stepsister
with lusty eyes?
He's getting redder by the second.
He turned away, but I can tell he's looking.
Guess I'll switch legs.
Ha, he looked! He definitely
looked! So easy to read.
To think the guy who's always
acting so cool-headed
would lose his composure like this.
O-Oh no! It's gonna It's
H-He's gonna see!
Huh, wait.
Hold on a sec. It looks like I'm
trying to seduce him, doesn't it?!
I think I got too carried away!
Japan Sinks
W-Wait
I know you were just trying to mess with me,
but didn't you realize this might happen?
You're usually so reserved,
but every now and then, you go and
do something outrageous, don't you?
Like this morning.
If you act like that at school,
you're gonna lose the reputation
you've made for yourself.
But you're family now.
I can't stand people looking
down on my family like that!
Thanks. I appreciate it.
Don't you have something to say?
I genuinely thanked you, didn't I?
D-Don't mention it!
I'm gonna go get in my pajamas—
The Bottom of the Sea
Ayai.
S-Stop The rules
I don't mind
losing today.
Mineaki-san, I'll hold the door,
so would you be a dear and bring that in?
Wh-What do we do?!
Just hide!
Hide? But where?!
Oh, sure!
Uh
Is it all right if I leave
everything in the corridor here?
Yeah.
Here!
Huh?!
We're home!
Oh? You alone, Mizuto?
Welcome home, Dad, Yuni-san.
Yume-san went to bed already.
Oh, okay.
Really? Aw, I brought back gifts.
Just now, if our parents hadn't come home
I was finally getting used
to how things are.
What was I thinking back there?
I'd almost gotten over the past.
It's things like this
It's things like this
Irido
That I can't stand about him!
That I can't stand about her!
My Stepmom's
Daughter is
My Ex
Where are you going, Mizuto-kun?
