Good luck
Good luck
(College Entrance Exam, Good Luck)
Good luck
Je-na…
Oh, Ye-ri.
Je-na, you are the hope of Chaehwa Girls' High School.
(Seniors, it sucks to be you today! Good luck on the CSAT!)
Je-na, you are the hope of Chaehwa Girls' High School.
Wishing you high scores on the exam!
We'll be cheering for you.
Good luck!
Th-Thank you…
Hello?
Je-yi.
I've always been afraid of you.
- Je-na, good luck.
- Good luck.
(Korea University)
Especially those deep,
dark eyes of yours.
(Mathematics Exam)
Your face, as if you knew everything
and were mocking me…
It drove me insane.
It's all your fault, Yoo Je-yi.
Being labeled as the one who can't surpass
her younger sister is maddening.
No one else could
possibly understand.
I just wanted to beat you
and regain Dad’s love.
When Dad found out
about my relationship with the teacher…
He praised me
with the gentlest voice.
It was a kind of praise
I had never received before.
I heard you have a daughter
who went missing thirteen years ago.
(Missing Child Search)
Stop looking for her.
Why? Why did you suddenly
change your mind?
Didn't we agree to keep searching
until this year?
Why are you so determined
to find that child?
Because if you find her,
you might agree to have a child with me.
Whether we find
Seul-gi or not…
We are not having children.
You should give up.
(Missing Child Search – Name: Woo Seul-gi)
Woo Seul-gi…
(Je-yi, I’ve always been afraid of you,
especially those deep, dark eyes of yours…)
No…
I’m not asking
for your help for free.
I’ll pay you.
I don’t need it.
Just pretend you never said anything.
I’ll help you find your daughter.
Let’s each do our best…
As fathers.
(Dad directly found Teacher Woo's weakness:
Woo Seul-gi… The daughter he lost long ago.)
Did Je-na know the teacher had a missing daughter,
and use that against him on purpose?
(Je-yi, I'm running out of money. I’m homeless every day…
Only now do I realize how lucky I was before.)
I swear, I didn’t go around
talking about it.
(Reporting on behalf of Dae Jun-dong)
Hello…
(I heard that Teacher Kim Seon-yeong from Chaehwa Girls' High
is on the college exam question committee. Is that true?)
Hello?
Teacher…
Teacher Kim Seon-yeong
violated the confidentiality agreement
and was removed from
the college exam question committee.
Ah, my father is
omnipresent and omnipotent
(Yoo Tae-jun)
I found your daughter.
(Student ID – Woo Seul-gi,
Gyungsun High School)
(J Medical Center)
(Parent-child relationship probability: 99.98%)
(Under construction –
Unauthorized personnel prohibited)
You don't want this video
to be sent
to the daughter you haven't seen
in 13 years, do you?
Teacher, please hand over
your phone.
(Turning off)
(Mathematics Conference Room)
(t is a real number,
assuming the line x = t…)
(College Entrance Exam D-1)
The plan is simple.
Just memorize the toughest problem,
and find a way to leave the exam site.
(Central Operating Room)
Friendly Rivalry
Lord of the living and the departed,
our beloved Heavenly Father.
Today, we gather for
the funeral of Yoo Je-na,
who, after long suffering from a brain tumor,
has been called to your presence,
and entered Heaven before us.
Born from the earth
and returning to the earth,
We believe this life, given and taken by You, our Father,
now reaches its destined rest.
Since all the family members are here,
it's time to close the coffin.
Although the physical body of our dear sister
Yoo Je-na disappears before our eyes,
we trust that on
the glorious day of the Lord’s promise,
she will rise again from death,
reunited with us
in a new and beautiful body.
Today, we part ways for now,
even if it is only a temporary farewell…
Yoo Je-yi.
You think so too, don’t you?
What?
This body is not Je-na's.
Look, there's a burn scar here.
Did your sister
have a scar like this on her foot?
Your father seems to have
quite an interesting hobby.
He collects unclaimed bodies
and uses them for surgical practice.
She was my senior
at the orphanage.
Choi Su-jin.
I heard that after she died,
no one claimed her body.
So the morgue storage fees
became ridiculously high.
But I also heard that the district office transfers
such unclaimed bodies to your hospital.
And Choi Su-jin…
Used to live right next
to your sister.
Is this really just a coincidence?
Now I get it.
My dad is a doctor
and a family member…
so I'm sure he went straight through the process
from pronouncing death to confirming identity.
And there was even a suicide note.
It’s perfect.
What are you going to do?
Are you really going to let
Choi Su-jin become your sister?
Yes.
Then Je-na will disappear
from this world forever.
If my dad’s plan is
to turn my sister into a dead person
and allow him to continue
committing crimes,
wouldn’t that actually
work in our favor?
If we disrupt Yoo Je-na’s funeral now,
my dad will definitely come up with a new plan.
Because he never knows
when to give up.
He cannot know that
we are aware of this.
Let’s go.
If you want to leave,
go by yourself.
There’s no way
I’m walking away from this.
I…
I’ve read your sister’s diary.
She wrote down in detail…
About how my dad died.
I need to find evidence.
Forget about
the evidence for now.
You’ll get caught
before you even find it.
Follow me.
I’ll buy you some time.
Hurry.
(Back Entrance)
(Building C – Endoscopy Center Main Hall)
Are you the young miss?
My mom said this isn’t
exactly a joyous occasion.
It wouldn’t be good
if a VIP’s identity got leaked.
She asked me to turn off the surveillance cameras
before my sister’s burial.
I’ll check with the director.
No need.
It’s my mom’s request.
That’s why she sent me.
Where did you go
during your sister’s funeral?
Then where were you
when she ended up like this?
Smile.
That’s what you do best, isn’t it?
Oh, right.
Today, you should be crying instead.
You’re a doctor, yet
you couldn’t even save your own daughter.
Who would trust you
with their life after this?
Well, when fragile children leave first,
for their parents, it’s almost a relief.
Je-yi, you’ve grown up.
I heard you’re good at studying.
But how will you handle this
in your senior year?
This is the most crucial time for you.
Only for those
who cram at the last minute.
I won’t fall behind just because
I stopped studying for three days.
How did you end up
with a kid just like you?
Thank you for the compliment.
(Je-yi, Dad knows everything…
Was the last thing the teacher left me a gift or a curse…?)
(J Medical Center Director –
Yoo Tae-jun)
Je-yi.
Dad knows everything.
Who is good…
And who is bad.
What’s wrong?
Can’t figure it out?
Want me to help you?
Are you here to show off?
This isn’t the time
to be staring blankly at the problem.
I don’t need your help.
Get out.
Get out!
I told you to get out…
Get out!
I must not cry.
Dad doesn’t give gifts
to children who cry.
("I must not cry. Dad doesn’t give gifts to children who cry.")
This sounds like a Christmas song lyric.
What could the gift be?
Did Je-na have something she wanted?
I don’t know.
Yoo Je-na is like my dad:
she loved birthdays, Christmas,
and anniversaries.
If it was the day before
last year’s exam…
November 15.
On this lonely, abandoned road ♪
I feel an unbearable urge to cry ♪
The reason I love you in secret ♪
Seul-gi, no.
Madam
Yoo Je-na.
A woman’s intuition is sharp.
Even when I wanted
to ignore everything…
(Teacher, this keychain feels like my guardian angel
– Je-na)
I couldn’t unsee it.
Because that child…
Was always lingering around us.
(I’ll bring your husband’s phone over. Please wait.)
All the unusual things
that happened after your father died
At first,
I thought it was all
that child’s doing.
(Yoo Je-na is dead.)
But then I realized…
Maybe Je-na was trying
to tell us something.
Please make way.
(J Medical Center Funeral Hall)
Framing you for stealing medication was
just a ploy to pressure me into settling.
Wait…
Did you agree to settle?
No.
I told them
I would never settle.
And they had the audacity to say
it’s because I’m a stepmother.
Do you think the same?
No. I think you did the right thing.
Where are you going?
Please keep this safe.
And don’t let the lawyer leave.
Hold onto her.
Seul-gi…
Me?
(Parking Lot)
Damn it, you scared me!
What are you doing?
You knew, didn’t you?
Knew what?
Don’t try to fool me.
I know you paid off
Su-jin’s rent and debts.
So what?
You came to attend
Su-jin’s funeral, didn’t you?
If no one had done anything,
she wouldn’t have had a funeral at all.
She would’ve just remained
in a cold storage forever.
At least now, she gets to ride a hearse with flowers.
That’s lucky, isn’t it?
You should try to move on too.
Do you really think that?
If you’re even remotely human,
seeing Su-jin end up like this
should at least make you feel guilty.
Yeah…
If you were human,
you wouldn’t have let us touch the drugs in the first place.
Hey, let me out of the car.
You’re not doing this
just for Su-jin, are you?
This X-ray can’t be used as evidence.
Why not?
Why wouldn’t it work?
Even if, as Seul-gi claims,
there were exam questions inside the body,
removing them surgically
wouldn’t have directly caused death.
Although he failed to inform the family of
the patient’s condition, which is medical negligence,
it doesn’t prove it was
the direct cause of death.
So trying to argue that
he had murderous intent…
Would be a stretch.
There are hundreds
of vinyl records there.
He killed people…
While listening to music.
He could have listened
while saving lives too.
Have you listened
to the recordings?
Yeah.
It’s a song by Lucid Fall,
Je-na’s favorite artist.
Completely insane.
So just like the diary said…
Je-na really was taken
into the operating room.
But there’s no surveillance footage
from the operating room.
So without Je-na's
personal statement in court,
or proof that the diary
is in her handwriting,
the only witness is now gone.
What are these?
Letters I’ve been receiving
since my husband died.
The sender knew about Je-na
and my husband from the start.
This person might be
willing to testify.
Maybe they were
the third person in the operating room.
Or someone from
the exam site or the school.
If they had decisive evidence,
why wouldn’t they have written it down?
They chose to
stay anonymous for a reason.
Even if we find them, convincing them
to testify will be difficult.
When’s the next court hearing?
Why do you ask?
I get that you want
to hold on to hope.
But as I just said, these pieces of evidence alone
won’t prove murder.
Unless we can bring
the dead back to testify.
(Crayons)
Stop playing detective.
Focus on your
college entrance exam.
If I were the defense lawyer,
I’d have plenty of questions
for the key witness — which is me.
But you don’t seem curious at all.
Then again,
pro bono medical lawsuits never interested you.
Yet you pretend to care about your client,
acting like a good lawyer.
- Choi Kyung
- Same with me.
Pretending to be a good mother,
a thoughtful parent…
Such a fake act.
Aren’t you curious how I knew
about Teacher Woo Do-hyeok and Yoo Je-na?
Yeah.
I’m not curious at all.
You probably don’t know,
but I love masturbating.
That day,
I was at school for that too.
Masturbating in the classroom the night before an exam
helps me relieve my anxiety.
And I just happened to stumble upon
Teacher Woo and Yoo Je-na together.
I wanted to expose them, but if I did,
they’d ask why I was at school at night.
I couldn’t answer that,
so I had to keep quiet.
All this time, I kept thinking
how great it would be if Je-yi was ruined.
If she disappeared,
I’d be number one.
She was the reason I never got attention.
It was so frustrating.
When I saw Je-na
at the school festival,
I told her this:
"I know everything.
If you don’t tell the truth…"
"I will."
But then Je-na died.
It felt like I had killed her.
I was terrified.
And you, as my mom,
all you ever did was pressure me to study.
Yoo Je-na’s death
has nothing to do with you.
Nor does the death of Teacher Woo Do-heok.
You will never have
to testify in court.
So never tell anyone
what you just said.
Understand, Choi Kyung?
That’s advice from
both your mother and your lawyer.
(Crayons)
(Business Hotel)
Unnie, you’re here!
Don't you have any zolpidem?
You mean sleeping pills?
I’ll ask around.
Don’t sell them to anyone else.
Sell them all to me.
I’ll pay you well.
Okay.
Go buy me some cigarettes.
You can keep the change.
Thanks!
Welcome.
What? What’s wrong?
I was just thinking
you and Seul-gi are exactly alike.
Why compare me to her?
I’m way prettier than her.
No matter how I look at it,
doing business with you is a loss for me.
Last time at the nightclub,
didn’t you take all the Concerta pills for yourself?
You saw Yoo Je-na at Gangnam Station,
but you never told me.
If you can’t even trust
your own partner…
I might as well
run the business myself.
I’d be a more reliable partner
than some high school girl.
So, can you get me Zolpidem?
If J Medical Center cooperates,
getting Zolpidem is no problem.
Just wait.
But why would a rich, model student like Je-yi
be selling drugs to classmates?
Don’t try to understand her.
Her brain is wired differently from ours.
Stop lumping me in with you.
It’s annoying.
Madam, how much
for our meals together?
One more plate of sundae, please.
(Translator's note: blood sausage)
That’ll be 5,000 won
with the sundae.
Thanks.
Anyway, be careful.
He's scarier than you think.
He killed Seul-gi’s dad too,
didn’t he?
Make sure you keep your promise.
I’ll contact you again.
