Friendly Rivalry
Hand over
Teacher Do-hyeok's phone.
If I don't hand it over,
you'll probably kill me, right?
Is Je-hyun a hostage?
Why is everyone
so bruised and battered?
I miss Je-hyun a lot
and I miss you too.
Don't say that.
Where have you been
all this time?
Dad knows about your relationship
with Teacher Woo, right?
That's why Dad killed Teacher Woo.
Do you have proof?
The video on the phone.
Even if it establishes a motive for murder,
it's only circumstantial evidence.
What about direct evidence?
Me.
I'm a witness.
Is that why you won't go home?
You have no idea
how terrifying Dad can be.
So give me Teacher Woo's phone.
You already searched it.
I don’t have it on me.
What do you plan to do
with the phone?
Will you really
keep your promise?
Je-yi
If this keeps up,
I'm really going to lose my mind.
Teacher Woo’s family deserves
to know the truth too.
Calm down first.
This is a decoy phone.
I’ll give you Teacher Woo’s phone.
Just reply to my message.
I won’t tell anyone I saw you.
Don’t worry.
I've set up an encounter.
With who?
With who?
You really can't reach Su-jin?
Damn it,
where the hell is she?
How come no one knows
anything about her?
Hey, Woo Seul-gi.
Are you listening?
Hey, Woo Seul-gi.
Hello?
Why aren’t you saying anything?
Hello?
What’s wrong with you?
Damn it.
I'll call you back later.
I heard you want
to apply for med school.
Seul-gi, have you ever seen
a dead body?
I got lost.
I'm sorry.
These are all
unidentified bodies.
Abandoned, with no relatives
looking for them.
Well
In order to perfect my surgical skills,
I come here to practice every day.
Isn't this
illegal?
They had no money for burial.
Even funeral homes rejected them.
I was kind enough to take them in.
I even dressed them up
and made them look presentable.
Isn’t that a good thing?
These corpses are a huge headache
for the district office.
Mass burials and such
Do you know how much taxpayer money that costs?
So pitiful.
She seems to have been
living on the streets after leaving the orphanage.
Lord, there is a lost lamb here.
Even though her body has perished,
may her soul rest in peace in God's kingdom.
If you want to study medicine,
you can't be afraid of blood and organs.
You'll definitely have to deal
with these things in the future.
But first, you need to behave
and get into university smoothly.
Je-yi.
Please, come in.
This is a detective
from the police station.
He's here to investigate
what happened on the school festival day.
Even though you're all busy studying,
please cooperate as much as possible.
Beom-su didn't have many friends.
She wasn’t being ostracized.
Our school doesn't ostracize people.
She just didn’t want
to socialize with others.
I often saw her
taking medicine.
How would I know
what kind of medicine it was?
I'm sure she wasn't
in good condition.
That day,
she was sweating a lot.
And drinking a lot of water.
Her eyes were bloodshot, too.
So I wondered
if she wasn't feeling well.
I don’t know anything.
(Medical Report)
I’m a victim, too.
I'm relying on the harp for university admission,
but she injured my hand, and now I can’t practice.
I’m screwed.
Beom-su said
she didn't make it into the top 20.
If there were no transfer students,
she would’ve made it.
So she felt it was unfair.
The transfer student
was the one who got stabbed.
Woo Seul-gi.
You must be busy.
Thank you for coming.
I just have a few questions.
The other students said
you are the closest to Seul-gi.
Is that true?
What is it that
you really want to ask about Seul-gi?
Why don’t you take a break?
You inherited
your father's stubbornness.
I’m in my final year
of high school.
Even getting injured
is a luxury.
Alright.
But remember,
don’t accept her apology too quickly.
Last time
when there was a guest at home,
you came back, right?
He was from the hospital.
Trying to settle with me.
Thanks for telling me.
Woo Seul-gi.
Wait.
What?
Hello, Principal.
Woo Seul-gi is at school.
What should we do?
Yes.
She’s right here
next to me.
I didn’t expect
to see you so soon.
But is it okay
without a guardian present?
This student has been
in an orphanage since childhood.
We’re aware of that as well.
First of all,
this is their crucial senior year.
Yet an incident like this has disrupted
the school’s academic environment.
I deeply apologize, Principal.
I have a guardian too.
Hello, lawyer.
The meeting is at six, right?
(Lawyer)
Wouldn’t it be better if I accompanied you?
I’ll go alone today.
If anything happens on the way,
please contact me immediately.
Alright, thank you.
No problem.
(Seul-gi)
Why is Teacher Woo’s wife at school?
I am Woo Seul-gi’s guardian.
As you all know, this incident has
seriously damaged the school's reputation.
Who was reckless enough
to call the police?
Principal,
that’s a strange thing to say.
There was a victim in this case.
The person who committed the crime
should face legal consequences.
Fortunately, Woo Seul-gi
wasn’t seriously hurt.
She returned to school
right away.
This was an issue the school
could have handled internally.
Yet it was unnecessarily
blown out of proportion.
I find that very regrettable.
I hope that before resolving the issue,
you sincerely apologize to us.
Forcing her to directly
confront the perpetrator
That’s too much
for her to handle.
You’re really going too far.
Wait a moment.
Who is the perpetrator?
Aren’t you being
a bit extreme with your wording?
Is there anyone here who doesn’t know
that Beom-su stabbed Seul-gi?
There were dozens,
if not hundreds, of witnesses.
The case hasn’t even been formally investigated yet.
Please be mindful of your words.
And if we only look
at the incident’s outcome
Although Beom-su made a mistake,
the reason behind it lies with Seul-gi.
Beom-su.
Tell them yourself.
Beom-su, it’ll be fine.
Just tell the truth.
Seul-gi was the one who told me.
I was really struggling
because my midterm results were bad.
She gave me those pills.
She said mixing them
would make me feel better.
Hey, Kim Beom-su.
When did I ever say that?
Woo Seul-gi.
Is this true?
No.
I never gave Beom-su any pills.
Seul-gi
If this is true,
we can’t just let it go.
What are you people
trying to do right now?
Seul-gi, let’s go.
No.
I didn’t do anything wrong.
Why should I leave?
I never gave Beom-su any pills.
Are you saying
our Beom-su is lying?
Woo Seul-gi,
you did sell drugs.
You even told me
how to mix cocktails with them.
Beom-su.
What kind of pills
did Seul-gi give you?
Teacher
She gave me
six white pills.
She said if I took them
with a pink pill, I’d get high.
If there’s drug dealing in school,
this is a very serious matter.
It must be thoroughly investigated.
Did she sell drugs
to other students as well?
I thought it was just a rumor.
Turns out, it all started
after the transfer student arrived.
I told you,
it wasn’t me!
I recently checked students' belongings.
I also interviewed some students.
They said they’ve been hearing
these rumors a lot lately.
Lately?
If it’s true, then it must’ve started
a long time ago.
We will immediately convoke
the School Violence Committee.
To discuss whether Woo Seul-gi
should be expelled.
The facts haven’t even been confirmed.
How can you expel her already?
The one who should be expelled
isn’t Seul-gi, it’s Beom-su.
How could you expel the victim?
It wasn’t me!
You’ve been denying it
from the start.
Do you know
who the real dealer is?
I’m with the
Gangnam Police Department.
Is Woo Seul-gi here?
We received a report
and must investigate.
Did you steal drugs
from J Medical Center?
What did you do
with the stolen drugs?
Did you sell them
to other students for money?
Why?
It wasn’t me.
Well, we’d like to believe you.
But we have evidence.
On the day of the health checkup,
you were caught on surveillance cameras
near the hospital’s pharmacy.
That was…
You wandered all over the hospital
looking for the pharmacy.
"I have something you need."
"Want to come get it?"
Did you sell the stolen drugs
to Kim Beom-su at the school festival?
She drank the cocktail recipe you gave her.
That’s what caused this whole mess.
If you confess now,
we can be more lenient.
Don’t you want to go to university?
It was Yoo Je-yi.
Yoo Je-yi?
She’s the one
selling drugs for money.
It wasn’t me.
It was Yoo Je-yi.
Hey…
Have you heard?
Beom-su went crazy
because of the drug’s side effects.
I heard Woo Seul-gi
was the one selling drugs.
- Damn it.
- So she’s the victim now?
- I thought something was off.
- Don’t you think it’s kind of cool?
I’ve never heard of anything
like this before.
Wasn’t Beom-su originally
planning to stab you?
Not Seul-gi.
Seul-gi.
Jo A-ra.
Come talk to the teacher.
What did you talk about
with the homeroom teacher?
How does it feel to have Woo Seul-gi,
whom you trusted so much, rat you out?
What nonsense.
Woo Seul-gi said the one who sold drugs
to Kim Beom-su wasn’t her, it was you.
So?
What did you say?
Are you still curious
about that?
Hey.
I never should have gotten
involved in this.
You have a father who can cover
everything up, even if things go wrong.
I could never compete with that.
I was an idiot
for trusting you.
That student’s name
is Woo Seul-gi?
Yes.
The school has been
in chaos over this.
It’ll be resolved soon.
Please don’t worry.
Of course, it should be.
Please make sure the other students
remain calm and aren’t affected by this.
I’ve been doing my best.
Let’s go.
I’ll take you home.
I have plans.
Then let’s talk.
Say it here.
Let’s talk another time.
I have nothing to say to you.
I’ll call you later.
I…
I don’t feel guilty at all,
Yoo Je-yi.
It wasn’t me.
Why should I take the fall for this?
What did I do wrong?
It’s always been like this.
Because I’m the easiest target.
In your eyes…
Am I just an ant you can step on
without ever fighting back?
Did you really think
I’d just let you crush me?
That’s right.
You did well.
Seul-gi.
Wow, look!
Seul-gi’s boyfriend is here.
Boyfriend?
Looks like he came
to carry his girlfriend’s bag.
So sweet.
Did you tell your classmates
I’m your boyfriend?
Then why don’t you pick up
your boyfriend’s calls?
I wasn’t ignoring you.
I was in class.
So? Where’s the medicine?
Did you really resist taking it?
A stab wound
must hurt quite a bit.
I can still endure it.
Whatever.
How have you been getting your meds
since coming to Seoul?
At first, I wanted to get a prescription
like I used to.
But Seoul is different from the countryside.
The regulations are strict.
Are you done with the useless talk?
Get to the point.
I bought them
through social media.
Social media?
By the way,
what was that business plan you mentioned?
Oh, that.
I looked into the market around here.
But I heard it’s all controlled
by some high school girl.
Do you know who she is?
How would I know?
I’m going to take her down,
then we’ll take over the market together.
What do you think?
Aren’t you ranked first in school?
That’s perfect for advertising.
“Taking these pills
is how I got so smart.”
That’ll be our slogan.
How’s that?
Pretty good, right?
So
Stop dodging the question
and just answer.
Who have you been dealing with?
(Consortine Seller)
Try placing an order.
Right now?
These accounts disappear
all the time.
They’re afraid of getting caught.
(KST 27)
(KST 27mg, 30 pills. Okay?)
(KST 27mg, 30 pills. Okay?)
Give me your account
and password.
Are you really going
to make Seul-gi a criminal?
Even if Seul-gi says a hundred times
that I was the one selling drugs,
no one will believe her.
And even if they do
it’s just a daughter messing around
with her dad’s hospital meds.
No one will say anything.
So take this chance
and stop selling drugs to students.
Dad’s been patient
for long enough.
To me, it’s just a joke.
But for Woo Seul-gi,
it could ruin her future.
I thought that’s what you wanted.
Why would you think that?
She was caught on camera
loitering outside the pharmacy.
She was always
an eyesore anyway.
Thanks to you, Je-yi,
we can finally get rid of her.
I know you had someone steal
Teacher Woo Do-heok’s phone.
There was something inside
that gave you a reason to kill him.
Something very interesting.
Oh?
“Seul-gi's dad is a predator
who assaulted students.”
If you want to brand Woo Seul-gi
with that label
then go ahead.
Now that I think
about it, Je-yi
You have
a pretty cruel hobby.
I guess I'll just have
to ask her myself.
See if she was really assaulted.
I’ll call Yoo Je-na.
(Choi Kyung)
She’s disappeared.
How would I have her number?
Though it looks like
even Dad doesn’t know where she is.
A series is a formula that
sums up the terms of a sequence.
When a series converges,
the limit of its general term is zero.
Now, let's look at
the contrapositive statement.
The contrapositive states
that the limit of the general term…
(Troublemaker)
We’ve arranged the meeting.
(Troublemaker)
6 PM at Gangnam Station, locker #4.
Alright, that’s the end of the explanation.
Let’s move on
to question 14.
"Payment is only accepted afterward.
6:30 PM sharp."
"Please be on time."
"Payment is only accepted afterward.
6:30 PM sharp."
"Please be on time."
Which one of them is it?
(Password?)
(1732)
You better hope
I don’t catch you.
Alright, that’s it for today.
Make sure to review.
Teacher, I have a question.
Damn it.
Where did all the stuff
in the clubroom go?
I got rid of it all.
What do you mean?
I sold everything.
To who?
Answer me.
Stop yelling.
Are you crazy?
You’re the crazy one.
Getting so chummy
with that country bumpkin.
What if Woo Seul-gi
set this up?
What if she’s working with the cops
to clear her name?
What if they’re trying
to catch the real dealer?
Then we’re all screwed.
Don’t worry.
I already reported it to the police.
What?
- Got it?
- Yeah.
If you have more questions, ask me.
Thanks, teacher.
This is the police station, right?
I’d like to file a report.
Woo Seul-gi will be caught
red-handed.
She will go to the
Gangnam Station locker.
(Seul-gi’s phone, Maebong Station)
I also planted drugs in her backpack.
The evidence is airtight.
Hey, Yoo Je-yi!
Where are you going?
Give me back my phone!
(Yoo Je-yi)
"The number you dialed is unavailable.
Please leave a message after the beep."
(Seul-gi’s location: Gangnam Station)
(Yoo Je-na)
Sis.
(Yoo Je-na)
I’ll give you Teacher Woo’s phone as promised.
Meet me now
at Gangnam Station, Exit 4.
I suggest you come
before I change my mind.
(Gangnam Station, 05:53 PM)
(Seul-gi’s location: Gangnam Station)
Damn it.
(Yoo Je-na: OK)
(Gangnam Station, Exit 4, 06:00 PM)
(Locker)
(Exit 4)
Driver, please stop here.
(Locker)
Damn it.
(New message)
(Unknown Number)
I’ll be there a little later.
I’ll bring your husband’s phone.
Please wait.
Hello?
(consortine000: Switched to Gangnam Station, Exit 8 locker)
Damn it, this dealer is so paranoid.
The location changed.
(Switched to Gangnam Station, Exit 8 locker)
Stay calm and act natural.
Seul-gi, don’t look back.
Just head straight to Exit 8.
Sis, you’re heading
toward Exit 4, right?
I put the phone in the locker.
(Locker)
Damn it.
Je-yi.
Thank goodness
you’re okay.
How much longer
until you reach the Exit 4 locker?
Let’s get out of here first.
Excuse me.
Wait…
Wait, let go of me.
Don’t do this.
Let go of me!
(Ambulance)

Hey.
I never should have gotten
involved in this.
You have a father who can cover
everything up, even if things go wrong.
I could never compete with that.
I was an idiot
for trusting you.
That student’s name
is Woo Seul-gi?
Yes.
The school has been
in chaos over this.
It’ll be resolved soon.
Please don’t worry.
Of course, it should be.
Please make sure the other students
remain calm and aren’t affected by this.
I’ve been doing my best.
Let’s go.
I’ll take you home.
I have plans.
Then let’s talk.
Say it here.
Let’s talk another time.
I have nothing to say to you.
I’ll call you later.
I…
I don’t feel guilty at all,
Yoo Je-yi.
It wasn’t me.
Why should I take the fall for this?
What did I do wrong?
It’s always been like this.
Because I’m the easiest target.
In your eyes…
Am I just an ant you can step on
without ever fighting back?
Did you really think
I’d just let you crush me?
That’s right.
You did well.
Seul-gi.
Wow, look!
Seul-gi’s boyfriend is here.
Boyfriend?
Looks like he came
to carry his girlfriend’s bag.
So sweet.
Did you tell your classmates
I’m your boyfriend?
Then why don’t you pick up
your boyfriend’s calls?
I wasn’t ignoring you.
I was in class.
So? Where’s the medicine?
Did you really resist taking it?
A stab wound
must hurt quite a bit.
I can still endure it.
Whatever.
How have you been getting your meds
since coming to Seoul?
At first, I wanted to get a prescription
like I used to.
But Seoul is different from the countryside.
The regulations are strict.
Are you done with the useless talk?
Get to the point.
I bought them
through social media.
Social media?
By the way,
what was that business plan you mentioned?
Oh, that.
I looked into the market around here.
But I heard it’s all controlled
by some high school girl.
Do you know who she is?
How would I know?
I’m going to take her down,
then we’ll take over the market together.
What do you think?
Aren’t you ranked first in school?
That’s perfect for advertising.
“Taking these pills
is how I got so smart.”
That’ll be our slogan.
How’s that?
Pretty good, right?
So
Stop dodging the question
and just answer.
Who have you been dealing with?
(Consortine Seller)
Try placing an order.
Right now?
These accounts disappear
all the time.
They’re afraid of getting caught.
(KST 27)
(KST 27mg, 30 pills. Okay?)
(KST 27mg, 30 pills. Okay?)
Give me your account
and password.
Are you really going
to make Seul-gi a criminal?
Even if Seul-gi says a hundred times
that I was the one selling drugs,
no one will believe her.
And even if they do
it’s just a daughter messing around
with her dad’s hospital meds.
No one will say anything.
So take this chance
and stop selling drugs to students.
Dad’s been patient
for long enough.
To me, it’s just a joke.
But for Woo Seul-gi,
it could ruin her future.
I thought that’s what you wanted.
Why would you think that?
She was caught on camera
loitering outside the pharmacy.
She was always
an eyesore anyway.
Thanks to you, Je-yi,
we can finally get rid of her.
I know you had someone steal
Teacher Woo Do-heok’s phone.
There was something inside
that gave you a reason to kill him.
Something very interesting.
Oh?
“Seul-gi's dad is a predator
who assaulted students.”
If you want to brand Woo Seul-gi
with that label
then go ahead.
Now that I think
about it, Je-yi
You have
a pretty cruel hobby.
I guess I'll just have
to ask her myself.
See if she was really assaulted.
I’ll call Yoo Je-na.
(Choi Kyung)
She’s disappeared.
How would I have her number?
Though it looks like
even Dad doesn’t know where she is.
A series is a formula that
sums up the terms of a sequence.
When a series converges,
the limit of its general term is zero.
Now, let's look at
the contrapositive statement.
The contrapositive states
that the limit of the general term…
(Troublemaker)
We’ve arranged the meeting.
(Troublemaker)
6 PM at Gangnam Station, locker #4.
Alright, that’s the end of the explanation.
Let’s move on
to question 14.
"Payment is only accepted afterward.
6:30 PM sharp."
"Please be on time."
"Payment is only accepted afterward.
6:30 PM sharp."
"Please be on time."
Which one of them is it?
(Password?)
(1732)
You better hope
I don’t catch you.
Alright, that’s it for today.
Make sure to review.
Teacher, I have a question.
Damn it.
Where did all the stuff
in the clubroom go?
I got rid of it all.
What do you mean?
I sold everything.
To who?
Answer me.
Stop yelling.
Are you crazy?
You’re the crazy one.
Getting so chummy
with that country bumpkin.
What if Woo Seul-gi
set this up?
What if she’s working with the cops
to clear her name?
What if they’re trying
to catch the real dealer?
Then we’re all screwed.
Don’t worry.
I already reported it to the police.
What?
- Got it?
- Yeah.
If you have more questions, ask me.
Thanks, teacher.
This is the police station, right?
I’d like to file a report.
Woo Seul-gi will be caught
red-handed.
She will go to the
Gangnam Station locker.
(Seul-gi’s phone, Maebong Station)
I also planted drugs in her backpack.
The evidence is airtight.
Hey, Yoo Je-yi!
Where are you going?
Give me back my phone!
(Yoo Je-yi)
"The number you dialed is unavailable.
Please leave a message after the beep."
(Seul-gi’s location: Gangnam Station)
(Yoo Je-na)
Sis.
(Yoo Je-na)
I’ll give you Teacher Woo’s phone as promised.
Meet me now
at Gangnam Station, Exit 4.
I suggest you come
before I change my mind.
(Gangnam Station, 05:53 PM)
(Seul-gi’s location: Gangnam Station)
Damn it.
(Yoo Je-na: OK)
(Gangnam Station, Exit 4, 06:00 PM)
(Locker)
(Exit 4)
Driver, please stop here.
(Locker)
Damn it.
(New message)
(Unknown Number)
I’ll be there a little later.
I’ll bring your husband’s phone.
Please wait.
Hello?
(consortine000: Switched to Gangnam Station, Exit 8 locker)
Damn it, this dealer is so paranoid.
The location changed.
(Switched to Gangnam Station, Exit 8 locker)
Stay calm and act natural.
Seul-gi, don’t look back.
Just head straight to Exit 8.
Sis, you’re heading
toward Exit 4, right?
I put the phone in the locker.
(Locker)
Damn it.
Je-yi.
Thank goodness
you’re okay.
How much longer
until you reach the Exit 4 locker?
Let’s get out of here first.
Excuse me.
Wait…
Wait, let go of me.
Don’t do this.
Let go of me!
(Ambulance)
