Friendly Rivalry
Je-yi.
I was wrong.
I'm sorry.
Was this also my dad’s doing?
No.
If you tell the truth,
I'll give you that thing from earlier.
Really?
Yeah.
I even failed at
stealing a phone.
Your dad doesn’t trust me anymore.
Did you steal Seul-gi's dad’s phone?
I stole it, but then
it got snatched away.
Someone took it.
Choi Kyung,
were you even listening just now?
I remembered something
from the school festival.
Beom-su was rambling,
saying she saw Je-na.
But when I asked her,
she turned pale with fear.
Your dad must have
asked her about it.
So I know that you guys
still haven’t found Je-na.
And I thought, as long as we use this as bait,
you’ll definitely take the hook.
Sorry.
Damn, you're really greedy.
Yeah, I’m totally money-hungry.
Isn’t it because I carry designer brands
that you guys treat me like a person?
Isn’t it because I have money that
you maintain this fake friendship with me?
Look at her,
she’s drowning in insecurity.
Did you really do all this
just to buy designer brands?
No.
My family went bankrupt.
Oh, come on,
now you're using your parents as an excuse?
I’m serious. I haven’t had
any allowance for a long time.
Our house got repossessed,
I can't even get inside.
I sold my harp just to get by.
I’ve become a beggar.
At least make up a better lie…
Then where do you sleep?
At a jjimjilbang.
(Translator's note: Korean public bathhouse)
You sleep at a jjimjilbang?
Who are you fooling?
Have you even been there?
Satisfied now?
You all probably think I deserve it
and are enjoying the show.
I just…
You’re so pretty.
You don’t look like someone
who sleeps at a jjimjilbang.
Be extra careful late at night there.
Have you eaten?
I stole your dad’s phone, you know.
And you're worried about me?
You're so damn annoying.
Thanks for being honest with us.
But why does Je-yi’s dad
need my dad’s phone?
What’s in it?
How would I know?
So…
You guys are looking
for her sister, right?
How could that old guy
possibly know Je-na?
He was at the school festival too.
What?
You and your sister really
do look alike.
Wait.
If you like the patches,
go find her.
No wonder your voice sounded familiar.
You're the one who gave me
the fentanyl patch, right?
Hey, Woo Seul-gi,
explain yourself.
Don't drink this.
This guy definitely spiked it.
Fine, you druggies
have fun on your own.
I'm leaving.
I originally thought
she was a guy.
Then I realized she was a girl,
and I felt awkward.
Seoul people are really something…
That girl Su-jin didn’t just steal drugs.
(Lee Min-ju)
She also took all the fake IDs
used to get prescription drugs.
That bitch left me with no way
to send someone to pick up the meds.
So?
You're still here?
So my sister has your fake IDs?
Looks like Su-jin
sold the IDs to Je-na.
Does your sister
take any medication?
She has narcolepsy.
She takes wakefulness-promoting drugs
like modafinil.
Oh? Or is she just
heavily addicted to drugs?
Why are you asking?
Can we talk in private?
That day at Gangnam Station…
You saw Je-yi’s sister, didn’t you?
We have to find her
to catch Su-jin as soon as possible.
Before that, answer me.
The high school girl dealing drugs
in the Gangnam business district…
It’s her, right?
If she’s gone,
we can sell drugs freely.
And you’ll be number one at school.
Want me to make her
disappear quietly for you?
Just kidding.
Why so serious?
I saw her sister taken away
in an ambulance.
At the time,
it looked more like a kidnapping.
Do you know
where that ambulance went?
Hello?
What?
Did you find Yoo Je-na?
I don’t want an autopsy performed.
Okay, I understand.
After all, a handwritten suicide note
was found in the hospital room.
Je-yi.
(J Medical Rehabilitation Center)
What happened to her face?
She fell from a mountain.
It looks like
she landed headfirst and hit a rock.

(Magnolia Hotel)
Hey, pass it over.
Here…
Throw it.
Nice!
Woo Seul-gi is out.
Hey.
Go easy on Seul-gi.
Hey, apply it carefully.
Don’t just smear it everywhere.
Well, your toenails are shaped weird.
Yellow nail polish.
Burn scar.
– Could it be…
– Seul-gi.
Did Je-yi’s sister really
commit suicide?
No.
I heard she already had
a brain tumor.
She was so sick. How could she have been
dealing drugs at Gangnam Station?
Some say she was pushed off a cliff
deep in the mountains.
What? So it was murder?
Who did it?
I heard…
It was Je-yi.
What the hell are you doing?
– What’s your problem?
– Are you crazy?
– She’s totally lost it.
– What the hell?
Stop!
Hey, Woo Seul-gi!
Why not set your goals higher?
(Korean University Rankings)
Try applying to Korea University’s medical program.
Back in your second year,
didn’t you want to be a doctor?
Me?
Je-yi and Seul-gi may be
ranked first in the school,
but they’re still under investigation,
so we can’t rule out their involvement in the crime.
The school won’t waste its one principal’s recommendation
just because of an ongoing investigation.
I think you should give it a shot.
Alright.
Thank you, teacher.
There’s a lot you need to prepare.
Get to work quickly.
Okay.
Just keep doing what you’re doing.
Stay out of trouble
and be a model student.
You get it, right?
Yes.
Good luck.

(Yoo Je-yi)
If the teacher simply ignores what happened,
I can go on living.
Otherwise…
my life would end
right here.
Please don’t give up on me.
Alright. As a teacher,
I will never give up on you.
So you…
You promised me, okay?
Sister.
Je-yi.
I knew it wasn’t thrown away.
Je-yi.
So it wasn’t just a rumor.
My dad was sleeping with a student.
I heard from A-ra that
you have my dad’s phone.
You saw what's in there, didn't you?
How did you
decipher the password?
I tried everything and couldn’t get in.
The day you went missing.
July 13, 2010.
Give it back now.
I lost it.
I originally thought my sister took it.
Do you know
the story of Cain and Abel?
The brother who killed
his sibling out of jealousy.
The Bible story.
All this time,
I always thought
my sister was going to kill me.
But…
In my dreams,
I was the one
who smashed my sister’s head to bits.
Looking at her lifeless body,
I felt strangely at peace.
Honestly, I truly hoped
that the police would arrest my sister.
Because that was
the only way everyone could survive.
I understand.
Je-yi.
This isn’t your fault.
I really never thought
that one day…
she’d just die like that.
She was such a coward.
There’s no way
she would’ve killed herself.
I never expected my dad
would take her away.
Really.
So, do you masturbate at school?
– Ye-ri!
– What? It’s not a big deal.
I do it all the time.
But since it's the day
before the exam,
it’s the perfect situation
for misunderstandings.
Right?
(Delete)
More importantly,
what surprised me more is that
you knew about Je-na and Mr. Woo’s relationship
and still kept quiet all this time.
That girl Su-jin
didn’t just steal drugs.
She also took all the fake IDs
used to get prescription drugs.
Looks like Su-jin
sold the IDs to Je-na.
"The number you have dialed is not in service.
Please check and try again."
Hey, stop crying and get out.
I need to clean up.
You should get a tattoo too.
I’m going to.
Is that Choi Su-jin?
No way.
That’s impossible.
(Drug Rehabilitation Center)
Miss… Are you okay?
Is that you, Su-jin?
You said she had
a burn scar on her foot, right?
I still remember her.
She said that scar was
the only thing keeping her going.
Something about how
having the scar…
Her parents were bound
to look for her.
That’s why she wanted to quit drugs.
Where is she now?
She left the rehab center.
Did she reunite
with her family?
No way.
After she got a little better,
she moved back to
the goshiwon where she used to live.
(Translator's note: goshiwon is a small single-room)
Is there any way
to find out the goshiwon’s address?
What exactly did Je-na hide here?
Beom-su clearly said
it was around this area.
Why didn’t you tell anyone else?
Who would’ve thought
Je-na would die?
I bet you just wanted to keep it for yourself
and sell it to Je-yi’s dad.
Damn it.

(Magnolia Hotel)
Excuse me, I’m looking for
the resident of Room 208.
She’s dead.
– What?
– She already passed away.
When did it happen?
About a month ago.
She owed a ton of rent
and never left her room.
When I opened the door to check,
she was dead inside.
What bad luck.
It was a huge hassle for us.
She had no family or friends.
I had to go to
the police station multiple times.
But today,
I finally got all the rent she owed.
What a relief.
You said you got the rent?
Who paid it?
Some guy who looked like
a thug or a troublemaker.
Said he was her brother.
Not only did he pay the rent,
he also went around settling
all her outstanding debts at local stores.
Je-na completely lost it.
Isn't this the last year's hardest
math question from the CSAT?
(Translator's note: CSAT is the Korean SAT)
