Friendly Rivalry (2025) s01e09 Episode Script
Episode 9
1
Actually, Je-na already
knew all the answers.
Time's up.
From now on,
for every wrong answer,
you'll get as many slaps
on the palm.
But rather than
hitting her sister,
she'd rather take
the punishment herself.
I can't live like this anymore.
I'm leaving you.
I told you,
divorce is not an option.
You need treatment.
Sister
Stop this endless bullshit.
We should just divorce.
What about the children?
I'm taking Je-yi with me.
That won't do.
Je-yi is meant
to inherit the hospital.
I'm willing to give up on Je-na.
Sister, your foot is bleeding.
Je-yi, let's get ready
for kindergarten.
Yeah.
At such a young age,
just to avoid
being abandoned by her parents,
she put in
so much effort.
Here, you eat.
She believed that
by being a good child,
the family would stay together.
This is the typical
"good daughter syndrome" of Korean eldest daughters.
Je-yi, wait for me.
Je-yi, let's go to school together.
However,
when Je-na realized
her sister
no longer needed her,
she began praying
to God for something else.
"The Lord is our refuge
and strength,
an ever-present help
in trouble."
"So no matter what
just give me a terminal illness."
"Let Dad, Mom,
and my sister all pity me."
"Please, help me."
- Je-na
- What happened to her?
What's the cause?
There's no specific cause
for narcolepsy.
Are you sure
it's narcolepsy?
It's hard to say.
Let's have her take the medication first,
and monitor her condition.
Thank you.
You must be busy studying.
And yet,
you brought Je-hyun to see me.
If you collapse on the street again
like last time, that would be bad.
Take Je-hyun with you.
No way.
Do you not realize
how dangerous exhaustion can be?
I don't need
Je-hyun with me.
Je-yi, you stay with me instead.
I have to go to cram school.
Forget it.
Give Je-hyun back to me.
Je-hyun, let's go…
Daughter,
how's your condition?
I'm not as drowsy anymore.
I feel more energetic.
I think I'm getting better.
Good thing the medicine is working.
You must have struggled a lot
with your narcolepsy symptoms before.
I didn't even know.
I was disappointed seeing you
dozing off while studying.
As both a father and a doctor,
I completely failed, didn't I?
I'm formally
apologizing to you.
It's okay, Dad.
There's no need to apologize.
You don't have to blame yourself.
Now that
we know the reason,
you can focus better
on studying than before.
As long as you improve in math,
I believe you can be
the top student in the entire school.
You can’t let Je-yi
take all the glory, right?
This is a situation that Je-na
did not expect to see.
Dad will now give you
his full support.
In our last lesson, we covered
the graphs and definitions of exponential functions.
Now, we are going
to move these graphs.
What are some ways
to move them?
There’s translation
and symmetry, right?
Okay, let's translate this graph
The so-called "support"
he promised
actually meant
a tighter surveillance.
It was a complete monitoring.
So, for exponential functions…

Je-na,
if you're still not feeling well,
you can leave early.
Or would you like
to rest in the nurse's office?
- Teacher.
- Yes?
This Korea University keychain
can I have it?
I feel like if I have this,
I'll get a perfect score in math
and be the top student in the school.

Je-na, why are you here now?
Yoo Je-na.
(Grade 2)
You…
You didn’t call my father, did you?
No, not yet.
Are you okay?
Then, what do you plan to do?
I'm still considering.
If the teacher simply ignores what happened,
I can go on living.
Otherwise, my life would end
right here.
Are you threatening me?
No, I'm just stating the facts.
And I will accept
your punishment.
Let me ask just one thing.
Is this your first time
doing this?
Yes.
Je-na, I think, you are very smart,
kind, and beautiful.
And you have integrity.
Can I ask why you did this?
Please don’t
Give up on me.
What did you say?
Please don't give up on me.
Alright. As a teacher,
I will never give up on you.
So you…
You promised me, okay?
Friendly Rivalry
Sister?
Je-yi?
What are you doing here?
What do you mean?
I should be asking you that…
So, you already know?
Dad killed Teacher Do-hyeok.
What?
That's Teacher Do-hyeok’s phone, isn’t it?
Hand it over.
What are you doing?
Is she crazy?
Yoo Je-na.
Who’s there?
Are you a student
from the boys' high school?
What are you doing here?
Hey.
Seul-gi!
What's going on?
There’s so much blood.
What do we do?
Call an ambulance!
What should we do?
"This is a school-wide announcement."
"Today's school festival has ended."
"All students should return
to their classrooms immediately."
"Parents and other visitors,"
"please proceed to the auditorium
and await further instructions."
"Repeating once more."
"Today's school festival has ended."
"Everyone on campus must follow
the school's instructions."
"Students, please remain calm
and return to your classrooms."
What's going on?
What happened?
Seul-gi got hurt.
Seul-gi?
How did she get hurt?
How bad is it?
Where is Seul-gi now?
Your dad took her…
Do you need my help?
Damn it,
where are the bandages?
Sit down first.
Kim Beom-su,
get yourself together.
Answer my question properly.
Have you been drinking?
Or…
were you on drugs?
Contact Beom-su's parents.
Get the school’s legal team here.
- Now.
- Got it.
We're still assessing the situation.
- Please don’t worry.
- No.
Wait a minute.
It’s not on our school.
Stop for now.
Nobody answer the phone.
Seoul people are really…
Hello.
(Emergency Center)
A student from our school was just brought in, right?
What’s the patient’s name?
Where is the director now?
Are you just going
to stand there?
Je-yi, do you want
to try suturing?
Once you seize the opportunity
and get a taste for it,
your goal of getting into medical school
will become even clearer.
In the first year of medical school,
we started practicing sutures on pig skin.
But pig skin is too thick, inconsistent in quality,
and frustrating to work with.
It didn’t have the texture I expected.
Then, in the second year,
we used donated cadavers.
It was our first time
suturing real human tissue.
You have no idea how soft and elastic
human skin feels when being sutured.
That night,
the tingling sensation
in my hands kept me awake.
But maybe because your friend
grew up in an orphanage,
she doesn’t have enough
fat in her skin.
There’s no elasticity at all.
Malnutrition during growth
can cause that.
But since she’s your friend,
I’ll be extra careful
so she won’t have a scar.
Can you pass me
the forceps over there?
Damn it.
It's not just marijuana
that's banned.
E-cigarettes are also prohibited,
Gu Chae-ryeong.
Understood?
Teacher, that’s just stomach medicine.
If you need it,
get it from the nurse’s office.
Don't bring it to school yourself.
Vice class rep.
Open all the lockers
at the back.
Teacher, what about the students
who aren’t in their seats?
Should we break the locks?
Leave it for now.
(Woo Seul-gi, Yoo Je-yi)
You still have the habit of taking patients
to surgery without the family's consent.
Were you planning to inform us
only if something went wrong again?
Was killing my husband not enough?
Now you're after my daughter?
Do you even deserve
to be called a doctor?
I want a hospital transfer.
If you can find a hospital
that will accept her at this hour, go ahead.
But since the suture procedure just ended,
there’s a risk of infection.
You’ll have to sign a waiver
before transferring.
Move patient Woo Seul-gi
to the VIP ward.

What do we do now?
What?
Where exactly are you?
Did you see my message?
This is worse than we thought.
Why are you panicking?
Did you stab Seul-gi?
No, it was Beom-su.
She was high on drugs
when she stabbed Seul-gi.
What if they find out
we were selling drugs?
"We"?
I told you never to do
in-person deals.
You were the one who ignored me
and sold to Beom-su directly.
Why drag me into this?
Watch your mouth.
No matter what,
I was only selling.
You were the supplier.
Think carefully.
The only person who knows
the drugs came from me…
is you.
But the number of people who received your origami cranes
and dealt with you in person is much higher.
Isn’t that right?
Stop panicking
and don’t act recklessly.
Just do as I say
and stay quiet.
This will all blow over soon.
(Jo A-ra)
There’s one more person who knows.
Woo Seul-gi.
You gave the drugs
to her yourself, right?
Can you trust her?
If she speaks up,
we’re both finished.
(Seul-gi's Location - J Medical Center)
I always knew you weren’t smart enough
to rank first in school.
But Choi Kyung,
are you really this stupid?
Why bring this up now?
What’s your problem?
You’ve seen how the school
is handling this.
Someone literally stabbed a student,
and all they want to do is cover it up.
The evidence is clear.
Of course,
the police should know.
Don’t say a word
about this outside.
- Mom…
- If you act recklessly,
and it affects your college entrance,
I won’t let it slide.
Listen to me.
Understand?
You call yourself a lawyer,
but you’re not even ashamed?
I understand the law too well,
that’s why I’m doing this.
Get out.
Damn it.

Why do all of you look down on me?
You all just have fun without me.
Why are you always lying?

(@tmstehrrr: There were self-harm photos, do you think there’s someone behind it?)
Seul-gi, are you okay?
Your wound must hurt.
But the sutures were done well.
You’ll recover quickly.
It’s stuffy in here.
Want to go outside for some air?
I also brought Je-hyun.
Hey, what’s wrong?
Sometimes,
I imagine Je-hyun dying.
What?
I’m afraid I’ll be too sad
when it actually happens.
So I try to picture it beforehand
to prepare myself.
Lately, I’ve been imagining…
what it would be like
if you died.
Have you seen my phone?
What?
Not this one.
I'm referring to my dad's phone,
which has disappeared.
How did that happen?
I hadn’t even managed
to unlock it yet.
So,
you knew my dad too?
I never took his class.
But…
I don’t think
he was a good person.
Why?
There were rumors that
he slept with students.
No way.
I’ll pretend I never heard that.
Why?
Isn’t that actually a good thing?
If your dad had been a great person,
wouldn’t that make things even worse for you?
What are you saying?
You’re really pathetic.
Not everyone lives like you,
Yoo Je-yi.
You’re not dead.
You’re still alive and well.
You're doing drugs with the hospital director's daughter
and ranked first in school.
Are you getting special treatment
at the hospital?
The internet is blowing up with the secret behind
Chaehwa High’s high college acceptance rates.
I have a great business idea.
Want to hear it?
You know,
I’m stuck in the hospital right now.
That’s why
I’m calling you in a hurry.
Start collecting
some painkillers over there.
But you really
can’t reach Choi Su-jin?
Damn it,
where the hell is she?
How come no one knows
anything about her?
Hello?
Woo Seul-gi.
Are you listening?
Hello?
Woo Seul-gi.

I’m calling you in a hurry.
Start collecting
some painkillers over there.
But you really
can’t reach Choi Su-jin?
Damn it,
where the hell is she?
How come no one knows
anything about her?
Hello?
Woo Seul-gi.
Are you listening?
Hello?
Woo Seul-gi.
