Stop right there.
The moment you open that door, I will call...
that younger sister of yours whom you love so much.
Come on, seriously?
Did you really love her or what?
I guess you did.
I'm getting a little mad.
What should I tell her first?
"Don't worry, honey."
"Moo Young says he loves you."
"He'll love you until the day he dies."
"You want to know why he dumped you when he loves you so much?"
"Because he's your brother."
"Oh, dear. You really didn't know anything."
"Don't tell me..."
"you slept together without knowing any of it."
"Oh, my."
"Did you really?"
(The Final Episode)
Kim Moo Young.
Did you...
really do it?
Why did you do that...
- to a person? - I'm not here to talk about that.
Then what?
Jin Kang...
can live just like right now, right?
- Jin Kang? - Yes.
Just like right now...
and from now on.
What are you talking about?
Does today's incident have something to do with Jin Kang?
No, it's not that.
Thank you.
I came here because I wanted to tell you that.
What are you thanking me for?
Thank you for protecting...
my younger sister, Yoon.
Your younger sister Yoon?
Yoon.
Jung Yoon?
Are you saying that Jin Kang is your younger sister?
No, that's not true.
Who said that?
Why is Jin Kang your younger sister?
Jin Kang isn't... You don't have a younger sibling.
You're the only child Kang Soon Goo has.
Who sad something ridiculous like that?
That wasn't true then.
Why are you asking me when you already know?
That's right.
Yoo Jin Kang is...
your biological younger sister that you've been looking for so much.
She's your real younger sister.
What is your name?
Yoo Jin Kang.
What's your resident registration number?
900407, 2819518.
What is your relationship to Kim Moo Young?
I was his girlfriend.
I am his girlfriend.
Manager Yoo.
You're going to Dowon Police Station to get Jin Kang, right?
Yes.
I think you should also know about this.
About what?
Jin Kang knows...
that she's not your biological sister.
What?
She said she knew since she was in middle school.
When did you know that Kim Moo Young killed Jang Se Ran?
Are you sure that he really killed her?
Do you think he didn't, then?
No.
I don't think he did.
Wake up.
Do you still think that Kim Moo Young is a suspect...
because they keep calling him the suspect in the news?
Kim Moo Young is already the killer here.
We already decided to disclose his personal information to the public.
(Seoul Dowon Police Station)
Jin Kang!
I told you that you didn't have to come get me.
Get in the car.
Didn't they give you a hard time?
No, I just answered what I knew.
Jin Kang knows that she's not your biological sister.
She said she knew since middle school.
What am I supposed to say if you say that?
I feel so bad that I don't know what to say!
Puberty?
I never went through puberty.
I feel so apologetic toward you...
even if I only looked at your face or your backside.
I felt so ridiculously bad,
that I could barely breathe all throughout my adolescence.
Jin Gook.
Yes?
If everyone says it's true, then it's true, right?
What do you mean?
About Kim Moo Young.
Everyone is saying that Kim Moo Young killed her.
Jin Kang also knows about...
Kim Moo Young's dad and you.
Jin Kang knows about Kang Soon Goo?
Sorry. I was the one who told her.
But I had no choice.
She'd already heard half of it from someone else.
Jin Kang.
Your real name...
is Jung Yoon.
Han Jung Yoon.
I'm sorry that I couldn't tell you sooner.
Let's find Moo Young first.
Then I'll tell you everything...
that you need to know.
Okay.
Get it together, Miss.
Do you really still think that Kim Moo Young is the suspect...
because they keep calling him that on the news?
Kim Moo Young is already the culprit now.
You should ask your older brother, Yoo Jin Gook,
about what happened...
between him and Kim Moo Young 25 years ago.
Your brother didn't hate him.
He felt apologetic and afraid, is all.
Your brother...
caused that person to die.
Who is Jin Kang, then?
If she's not my younger sister,
why is Jin Kang in my memories...
and why is she in the drawing I did of my family?
Because you treasured her.
Because you treasured her and loved her more than family.
- I did? - Yes.
Jin Kang's real name is Han Jung Yoon.
She had a name, but her birth wasn't even registered...
until she was four years old.
Because Jin Kang's parents were too obsessed with their cult.
Her parents dragged your mother into the cult,
and your mother even secretly took the deposit from your house...
and ran off with you in tow.
So that's why...
Dad did that to Mom.
That's right.
And he killed Jin Kang's parents.
Jin Kang is...
the daughter of Han Jong Soo...
and Park Jung Hye, whom your father killed.
JIn Kang can continue to live on without knowing this, right?
About the past.
Promise me...
that she'll continue to be able to live as she is now.
That's good, then. I'll be going now.
Turn yourself in.
Turn yourself in. That's the only way out for you.
I'm so angry.
I feel like somebody toyed with me so much that...
I can't bear it.
I need some time to think about this.
Moo Young.
It's not your fault, Mister.
It's not your fault...
or Doctor Yang's fault.
You can't win against me anyway.
You've never been able to because of your guilt toward me.
Give me just three days.
I'll be in touch after three days.
(Written Will)
No, Moo Young. No!
Jin Kang.
What are you doing there?
Why did you do it to him?
What?
Why did you stab him?
What?
You said you didn't hate him, but were sorry to him.
You should've apologized then.
You should've asked for forgiveness if you were afraid.
How could you...
stab him with a knife?
Okay.
Right, I was wrong.
You were wrong.
Right.
He isn't the person whom you used to know.
He told me that he wanted to start afresh.
So there's no way he killed her.
I don't buy it.
I'll never believe it unless I hear it directly from him.
Jin Gook, I...
It isn't like a cold.
It isn't like something that gets better after suffering a little.
I...
I don't think I can live without him.
I might end up dying without him.
Don't worry.
I'll...
find him. I'll find him no matter what.
Don't worry. Don't you worry.
I should've stopped him from leaving by any means possible.
I saw how his anger and disappointment...
all turned to self-hatred...
when he found out that his father was a murderer.
If he committed a murder,
he wouldn't be able to bear it anymore.
That is why I must find him.
I'll find him.
Okay.
I'll look into places he might go once again.
Thank you, doctor.
Chairman Jang Il Gun...
who lost both his eldest son and daughter...
couldn't hide his deep sadness.
He left the airport without answering any reporters.
Jin Kang.
Jin Gook isn't home.
I know. I stopped by the office and came here to see you.
I wondered how you were doing.
I'm fine.
Did you change the door passcode by any chance?
- No. - Let's change it now.
Why?
I was frustrated because he always said...
he'd change it without actually taking an action.
Now, I'll finally be reassured.
Are you done?
Yes.
It isn't about your personal information like birthday, right?
So Jung, is it because of Moo Young?
What?
Actually,
he came to the house.
The house? My house?
Yes, twice in secret.
Once, he came with a gun.
A gun?
It's not going to happen, but just in case.
Don't tell me it's because my brother did that...
to his father.
When?
The day when you worked overtime and told me to come over for dinner.
(I'm working overtime today, so can you go have dinner with Jin Gook?)
(So Jung)
What time do you finish work today?
10pm the earliest?
- The police have four shifts? - Yes.
They work in four shifts regardless of weekends.
Most police officers are busy even on their day-offs.
But it's not the case for my brother.
He rests no matter what.
When are his day-offs?
The 4th, 8th, and 12th of this month.
Multiples of four.
Then he must work in the daytime today.
You're here because of Moo Young, aren't you?
Then again, I was shocked when I watched the news report too.
Do you think...
he killed Jang Se Ran?
What about you?
I can't believe it.
I think he did.
He does whatever he puts his mind to it.
If he has the will, he's capable of even worse things.
What's so important about grocery shopping?
- You said you wanted to start anew. - And?
Then you should live in a warm house.
A warm house smells like warm rice.
Thank you for the food.
They're having difficulty investigating the case.
But you think he's no longer Kim Moo Young...
because he killed someone?
At least,
he doesn't harm those who did nothing to him.
The investigation is currently...
I'm sorry, but can you take me to the Dowon Police Station?
The police announced that they'd strengthen...
the search and seizure investigation on NJ Group.
There he comes.
- Hurry. - He's coming out.
Please tell us the progress.
- Look here. - Please say a word.
Director Choi, this is Yoo Jin Kang.
Director Choi, what did you say to him?
Director Choi, you know what happened.
What did you tell him?
Where is he?
Director Choi.
(Chairman Jang)
Yes, Chairman Jang.
You two were neglected.
The grown-ups were obsessed with religion...
and you were the one who took care of Jin Kang.
You meant the world to her.
That's probably why she stopped talking when you disappeared.
She didn't say anything for the first three months with me.
She'd sit on the floor and stare at the gate all day.
When the sun went down, she'd start crying.
She'd never stop crying.
Even after she started opening up to me,
she'd follow him whenever she saw a boy about your age.
What's wrong?
It's okay. It's all right.
You did it.
You planted love in her heart.
I hope that's true.
But I can't believe it.
The burn on your right shoulder...
is the evidence.
I shot your dad, and he fell.
After hearing the gunshot,
Jin Kang came in from the yard.
She didn't know what was going on.
While running, she bumped into the heater.
And the boiling kettle fell from the heater.
You protected her...
from the boiling water.
With your tiny body.
That's why your burn is bigger than hers.
I feel proud...
of my ugly burn now.
I'm sorry.
After all you did for her...
Why are you crying?
Are you crying because you're sad or because you're happy?
Because I'm happy.
What are you happy about?
The sky.
The sky?
Yes.
It's so beautiful.
Why didn't I know before?
There are...
so many beautiful things in the world.
Yes.
That's right.
A long time ago,
we were here.
We were?
And I was very nice to you then.
- Really? - Yes.
If I tell you everything, you’ll want to pay me back.
Pay you back?
Sure, I will.
So...
stay with me for a long time.
Moo Young.
I went to my house.
Your house?
You mean the house your family lived in when you were little?
Yes.
Where is it? How did you find it?
I just stumbled upon it.
In a forest.
In a forest?
Yes. It looks like a picture.
Like a picture?
(Mount Geumah Mortar)
It's a lie.
I was just hoping to find a house like that in that forest.
What's with you?
I was so happy because I thought you really found it.
Would it have been nice if I really found it?
He found the house.

(Seoul to Haesan)
(Departure at 05:35)
("Tragedy brought by fanaticism")
("He killed 3 devotees and committed suicide")
The Mount Geumah murder case. November 1, 1993.
The criminal, Kang Soon Goo.
Victims, Lee Mi Young, Han Jong Soo, and Park Jung Hye.
He had a grudge against his wife...
for running away with their son after getting in a cult.
He found out the hideout and killed his wife and the married couple.
The criminal Kang Soon Goo died on site...
from Haesan Police Station Constable Yoo Jin Gook's shooting
Kang Soon Goo's son Kang Sun Ho got burned...
and was sent to Haesan Hospital.
Han Jung Yoon, the daughter of Han Jong Soo and Park Jung Hye,
also got burned and was sent to Haesan Hospital.
Jin Kang?
(Mount Geumah Mortar, 5:35pm Mugunghwa train)
(Mount Geumah Mortar)
The number you have dialed is not available at this moment.
Hello?
You're Detective Yoo Jin Gook, right?
Yes, that's me.
I'm a friend of Moo Young.
Yes, please talk.
Moo Young told me that I had to call you three hours later.
But I was too anxious.
He told you to come to the place where you first met Kang Sun Ho.
He said you would know if I just told you that.
To tell the story that I want to tell,
I will have to quickly end the story that I must tell.
I don't think that the things you said were wrong.
If not having a heart makes you a devil, I really didn't have a heart.
I don't know the reason.
I always thought that people were strange.
They became happy because of strange things,
became sad because of strange things,
and became angry because of strange things.
Kim Moo Young, you know what this means, right?
- What do you know? - I hated people some days,
and they entertained me some days.
I bothered the things that I wanted to bother,
and observed the things that I wanted to observe.
If someone started a fight, I fought.
- Take this and leave. - At that moment,
I wasn't even interested in Yu Ri or Seung Ah.
- Don't get caught. - In the end,
I knew that I would win.
Jin Kang told me to become a good person.
Promise me that you will become a good person.
Teach me.
I wanted to become a good person,
but I became a murderer.
I'm sure that no one will understand me, but I want to say this.
I'm regretting it.
Regret?
Are you writing a letter of apology?
If I got ruined,
I thought I would be the only one ruined.
It's my fault. I'm asking you a favor.
Please don't bother them.
I really felt that I was a human that day.
I killed someone when I felt like a human the most.
I realized my life was over because of that.
Yoon!
I'm hungry.
Are you hungry?
Wait a minute.
- Don't let us sin. - Don't let us sin.
- Please let us become one. - Please let us become one.
Yoon, how many peanuts do you want to eat?
How incredible. You came all the way here.
I had something to ask you.
You got this because of my brother, right?
Yes.
So that you could kill my brother.
Yes.
You brought it all the way to our house, right?
Yes.
And the reason why you asked me what time he gets off late shifts...
and the time he was relieved from his shift...
was all because of that, right?
Yes.
Did you really intend to kill him?
Yes.
But I couldn't kill him because someone came.
That's why you broke up with me, right?
Because my brother...
caused your father to die.
Yes.
Is there anything else besides that?
What other lies...
do you have prepared for me?
What are you actually hiding...
while saying "Yes, yes"...
with that wicked look on your face?
There's nothing like that.
What are you doing?
I'll die if I do this, right?
That's not a toy.
Exactly.
Stop being annoying. Give it here.
I feel bad...
because my brother caused your father to die.
So I'll die instead.
Give it here.
Tell me that you won't die.
Give it here.
Promise me that you won't die.
Stop it.
Are you out of your mind?
Do you really want to die?
No.
I want to live.
I want to live on together with you.
- Kim Moo Young. - Leave.
I won't go alone.
Your father killed my parents, right?
I got scared after hearing that.
About the fact that my parents passed away like that...
and that it was your father's doing, too.
That's how I found out how this feels.
When you found out...
that my brother killed your father,
this is how you must have felt.
That's why you said that to me, right?
You're just you.
What?
No matter what happens,
you're just you...
to me.
To me, you're just you.
I killed someone.
You can just turn yourself in.
You can receive your punishment and start over.
I've already come too far.
And I can't go back and change it.
I just...
want to die.
You really are terrible.
You truly are inconsiderate.
What will become of me, then?
What am I supposed to do?
Go back.
To where?
To the time before you met me.
Even though we've been together from the start?
This is me.
If you die, I'll die too.
I was only here because of you from the very beginning.
So I can't go anywhere without you.
Do you really want to die...
despite my saying this?
No.
I want to live.
Jin Kang.
Jin Kang!
I love you.
I love you too.
Jin Kang...
No...
Bye, Mr. Yoo.
Please don't be sorry to me now.
25 years are enough.
(To Mr. Yoo Jin Gook)
November 22, 2018.
(From Kang Sun Ho)
From Kang Sun Ho.
PS.
(In the afternoon one day)
In the afternoon one day,
I missed something and started my journey.
I walked, walked, and walked again.
I bumped again and again...
I'm sorry. Are you okay?
Then I met Jin Kang.
I'm sorry.
I knew it.
What did you know?
I knew you weren't so pretty.
Hey, do you know me?
- And... - No, not at all.
I started to breathe again.
You're here.
Yes, I'm here.
