Nobody Knows (아무도 모른다)

The story you made up actually happened.

You're saying you killed a person...

because of my lie 19 years ago?

Not yet!

I have something to tell you.

- Now? - Ms. Cha.

What were we talking about?

Eun Ho, call me back when you get this.

Let's go.

Now!

- Who are you? - I'm Eun Ho's homeroom teacher.

Eun Ho got into an accident and is currently at a hospital.

There are traces of violence on his body.

Those aren't because of the fall.

- He fell from a hotel. - Millennium...

How did you know that?

Detective, I'd like to check it too.

I need to know what happened to Eun Ho.

Ha Min Sung. He goes to Shinsung Middle School, right?

He's in my class.

All these can't be a coincidence.

Eun Ho found money at the bathroom in the hotel.

He suggested that we split the money.

Yesterday morning,

you said Dong Myung was in Eun Ho's class, right?

It's this way.

I've seen this...

when I was little.

Seo Sang Won.

What did you just say?

I heard you said: "Seo Sang Won."

- Am I right? - Yes.

Why did this drawing remind you of him?

He's the murderer of the stigmata serial murder.

I saw this at church when I was little.

Sun Woo.

I hope...

you will...

be selected by the angel in the future.

What happens then?

A miracle will happen.

That pastor was Seo Sang Won.

They were blessed instead.

They were scared when I chose them,

but at the last moment,

they were happy.

So I invited you and waited for you.

To show a miracle to you...

that has remembered me...

and looked for me desperately.

Where did Eun Ho see this?

Detective Cha?

Wouldn't he have seen it at school?

Shinsung Foundation was created by New Life Church.

I don't think so.

Our school has never done any activities...

related to religion since the current chairman.

How long has it been since you came to this school?

I came here at the end of last year.

- But... - You're...

- a science teacher, right? - Yes.

May I know when that note was taken?

It was about a month ago.

I'll check the exact date and let you know.

Okay.

Which class is Dong Myung in?

He's in the next class.

- Yes. - I just sent Dong Myung's...

communications data and the map of where we picked up his last signal.

It's near Myungin Hospital in Yeonhui-dong.

- Okay. - When he registered his phone,

his father was the guardian, so we also have his father's number.

The number you have dialed is not in service.

Detective Cha!

Take a look at this.

(Mother, me, older brother, and mother)

Can I have the phone number of Dong Myung's mother?

I don't have it.

What's the occasion?

I'm looking for Dong Myung.

He said he was going home yesterday, but he just disappeared.

Do you...

know anything about Dong Myung's younger brother?

Hello?

Ms. Kim?

Is this about Eun Ho's accident?

The vice-principal was investigating...

I mean, he was looking into it.

He also told me to find out if Dong Myung was...

bullying other students.

Especially, Eun Ho.

Dong Myung's father is serving his time in Seoul Southern Prison.

- On what charge? - Fraud and blackmailing.

Dong Myung's brother is in his aunt's house.

Here's the number.

- Did you make a call? - No.

The last signal of her phone is near here.

I'll give you a call when I find him.

No, wait.

- You'd go there alone? - You have to stay at school.

No, I have to see with my both eyes if Dong Myung is safe.

I'll give you a call.

He suddenly disappeared when he said he was going home!

I should have asked where he was going,

not if he was going home.

Though I've seen for myself what is home was like,

I was inattentive.

You just wanted to look away from it.

I also acted the same way when I first saw Eun Ho.

And I'm not going to look away any longer.

You can face Dong Myung as a detective.

And I'll stand by him as a teacher.

Organize this.

All right?

(Choi Dae Hoon's route on the day of the incident)

Yes, Detective Cha.

I checked Kim Chang Soo's house and his office,

but there weren't any traces.

- And the hotel's security camera? - Well...

The person in charge isn't picking up.

And?

- Can't they give us the footage? - For now.

They want the letter of cooperation first.

Those jerks.

Is the security manager we called last time in charge?

Yes.

But his phone is turned off.

Ms. Yoon is there, right? Put her on the phone.

Yes. Hold on.

Here.

Yes, Detective Cha.

Can I ask you another favor?

Sure. Tell me.

Yes.

All right.

Yes, Detective Cha.

She hung up.

She wants us to search...

Choi Dae Hoon's house for now.

Why would she ask you to do that?

You're coming with me?

I was going to hire a caregiver anyway,

so thank you.

I will pay for the expenses separately.

Haven't I told you that I'll take care of Eun Ho?

I'm really grateful,

but why would you offer all this for Eun Ho?

Taking responsibility for the accident.

Isn't that enough?

It's a very good attitude.

You're right.

You should beware of excessive favors.

Most human beings don't deserve a free lunch.

However,

Eun Ho deserves it.

He saved a person.

If it wasn't for Eun Ho,

he would've become ashes by now.

Goodness, what am I saying?

Actually,

I was raised by a single mom too.

Well, those were...

rough times for my mom and me.

That was inside Eun Ho's bag.

Why did he have a children's book?

I'm wondering the same thing.

Apparently, he read it when he was little.

Apparently?

Who said that?

The police who lives on the upper floor of my house.

You have a good neighbor.

- Tae Hyung. - Yes.

Come.

Have you read this?

- No. - You should read some books.

Good. Read this to Eun Ho.

Take it.

Have you read it, Chairman Baek?

Yes.

The friendship and compassion of the boy and the woman...

who weren't blood-related were impressive.

Welcome.

He didn't come here.

Dong Myung wasn't far from here yesterday.

He didn't come.

Then do you know any place he might be during the night?

You're not even Dong Myung's homeroom teacher.

Why are you here?

He must be in serious trouble this time.

When the detective called and asked for him,

I didn't think of it much.

But seeing a high ranked detective...

come to look for him, he must be.

Did you get the number of the detective who called?

Yes. Wait a second.

Here it is.

(Incheon Police Station, Shin Min Chul)

It's the detective we saw at the hospital, right?

How did he know Dong Myung and called?

Why did he ask for Dong Myung?
