Nobody Knows (아무도 모른다)

Don't worry. You'll go down slowly.

I don't want to do it.

Why? Are you scared?

You still need to do it.

Are you not going to do this in case of an emergency?

I can't do this.

Fine.

Make sure you remember everything you learned today.

Okay.

- Please let her go. - Okay.

- Be careful. - Hyun Jung.

Yes?

If you want to survive, do it.

If you want to live.

Hey.

- Are you okay? - Yes.

- Good job. Please help her out. - Okay.

You just saved Hyun Jung.

It's not time to be proud.

It's your turn.

Get ready. All right.

It looks scary.

- Watch and learn. - Okay!

Be careful.

Get ready and step forward.

Mr. Lee.

What in the world are you doing here?

Eun Ho...

What about him?

He didn't get pushed by someone.

To live...

To survive,

he jumped off himself.

He knew it wouldn't reach the ground.

Although he knew it,

he wanted to live.

That's why he jumped off.

What on earth was chasing him?

He's just a 15-year-old kid.

Your nails got longer.

Ko Eun Ho...

We should kill him once he opens his eyes, right?

That boy jumped off from this height to live.

Of course, he's too young to be killed.

Still,

he's out of my control,

and he's the result made by Ms. Cha Young Jin.

- Don't you think so? - Sang Ho.

Things are getting messy.

We shouldn't have kept him alive in the first place.

Is that when things started to go wrong?

Or...

Gosh. Mr. Jang.

I didn't expect to see you here.

I heard...

you've been away for a few days recently.

Where have you been?

You went somewhere nice all alone?

How have you been?

If you lock the doors like that, how will you get out?

Don't worry. I already have a way.

Have you been well?

Yes.

You look well.

Where are you going?

I'm not going anywhere.

We haven't met for a long time. We need to talk.

Let's save it for later.

You'll only get hurt if you run in a rush at your age!

See you later.

Mr. Jang.

Mr. Jang!

Doo Seok.

I lost him.

Me?

I'm locked in.

Yes.

What's his name?

Ko Eun Ho?

Ko Eun Ho.

Ko Eun Ho.

Go after that boy.

If he has the stuff, Ki Ho will have to come see him again.

Why don't you let them go?

They've had enough.

Were you still here?

What should I do with the boy?

He saved someone's life, so he deserves an award.

Here at the Shinsung Middle School,

I've seen light and darkness today.

It's not here.

Good job.

"I stood before a mirror several times..."

"and imagined how I would change..."

"if life tramples over me."

"I put my fingers in my mouth..."

"and opened my mouth to the sides, grimacing my face and thought,"

"would I look like this?"

It looks quite fun.

Come on, Mr. author!

You can't close the book this way.

He shot himself to death...

He had such a vain hope.

No wonder he ended your life that way.

This is how I would have written it.

"I must save them."

((I can't tell you. But please help me.)

He's quite daring.

Hee Dong, where do you think it went wrong?

Well,

if I didn't lose Ki Ho...

You scumbag.

If you got the bag as soon as Eun Ho left the emergency room,

it would have been over by now!

What's wrong was...

Eun Ho's mind.

His kindness ruined our plan.

If I were to go back in time, I'd tell little Eun Ho...

that ill will always comes back as ill will,

but goodwill doesn't always come back as goodwill.

Being evil is clear, but being good is...

complicated...

and it often betrays you.

Come in.

Hello.

Thank you.

When is your brother leaving the hospital?

In two weeks.

Come and get a haircut later.

I won't charge you.

I'm sorry.

For what?

For being friends with Eun Ho.

Was it when he was seven years old?

He helped an old man collecting waste paper.

I didn't like it, but I let him because I thought he'd quit soon.

Then that old man...

kept bringing Eun Ho around to make him work.

My mother was pretty insignificant.

This is what she always said.

"Everyone will look down on you if you're kind. Be spiteful."

But she's right.

They look down on you if you're kind and you'll suffer losses.

Although Eun Ho did suffer losses,

at least he's got a friend.

I'm sorry.

I should be...

sorry for Eun Ho...

for being his mother.

He had never spoken ill of you.

I'm sure he never said good words about me.

I'm sorry.

My gosh.

He jumped off on his own.

He jumped off on his own.

Do you think Eun Ho rappelled down?

When I first heard that he fell from here,

I thought it was a miracle...

that he was still alive.

But if you fall from this height,

it's like a car crashing head-on into a cement wall...

at 95 km per hour...

without a seat belt or an airbag!

But since it was that high,

he must've thought he had a chance of surviving,

so he untied his belt.

But even at that height...

Mr. Lee.

- Yes. - If he rappelled down,

it couldn't have been this life line.

Why would there be a life line that's far shorter than the height?

Right.

You're right.

Even if the rope was cut,

this rope must've been tied here...

when the employees of the hotel found him, right?

It must've been impossible to unfasten the safety rope...

without leaving a trace after he fell and before he was found.

That means he didn't fall because the life line was defective.

I'm sure the culprit didn't expect...

Eun Ho would use the life line to go down.

There's no reason for them to place a life line that's too short...

for this building in the first place.

It was replaced after the incident.

To destroy evidence, the culprit replaced the life line.

But he made a mistake of replacing it with a shorter one.

Then do you think...

there's another criminal...

among the insiders of the hotel?

If the criminal was working in the hotel,

that explains why he had to bring him from the abandoned building...

to the hotel.

That's why it's strange.

Why would he commit a crime...

at his workplace?

And this is a hotel.

Ms. Cha.

If you're hiding something from me,

please be honest and tell me.

There's more, isn't there?
