Nobody Knows (아무도 모른다)

We'll continue learning...

about the energy sources today.

As for the sources of energy, there are three major nutrients...

and two micronutrients.

The three main nutrients include carbohydrate, protein, and fat.

And two types of micronutrients are vitamins, minerals, and water.

These aren't directly used for energy,

but they're necessary to maintain our lives...

Why did you do that, Eun Ho?

Are you not scared of me?

I might go find you.

Thank you.

Dong Myung never bullied me.

So Dong Myung behaved that way...

just because you two are close?

Yes.

We're not friends.

I always got things from him.

How are we friends?

At the school I worked previously,

I had...

a victim and a perpetrator of school violence in my class.

Will you keep your mouth shut?

Fine. Do as you want.

You won't believe me, will you?

You won't believe me no matter what I say.

I only listened to the victim...

and transferred the perpetrator to another class.

I didn't try to find out what actually happened...

to those kids.

I didn't want...

to make the same mistake again.

- Yes, Mr. Lee. - I will send you...

the date of the class when Eun Ho drew...

the angel in his notebook.

- Okay. - Ms. Cha.

Are you with Eun Ho now?

I am.

- I'll head there now... - Where are you now?

I'm still at school.

I'll go there, then.

Hello. I'm Kim Tae Hyung, Eun Ho's caregiver.

- Hello. I am... - You're his neighbor, right?

Yes.

And you're a detector of the SCS.

And...

you're Eun Ho's friend.

- Did Eun Ho's mom tell you? - No.

I heard it from Chairman Baek.

Oh, I heard he had it in his bag,

so I'm reading it for him. Have you read it too?

Is it okay to read it to a teenager like Eun Ho?

I'm sure he's already read it.

Right.

He's no longer a kid as he's 15.

- I'll get going. - Okay.

Take care.

He is still a kid.

- Sorry? - He's only 15.

Okay.

Yes. Go ahead.

Detective Cha had been here until a while ago.

She left the hospital to go see Eun Ho's teacher.

How is his condition?

He's half-unconscious, so I can't wake him up.

But he reacts to strong stimuli.

It won't take long, then.

- Keep your eye on him. - I will.

Ki Ho,

he prayed for a long time on his knees.

Whom would he have prayed for?

That kid saved my life.

You appeared out of nowhere and asked to help you hide.

And now you want to see him?

I put a too heavy burden on him.

I need to get it back.

You have something to get back from him?

Yes.

Why? You need to find Ki Ho?

Of course. He's our family.

Moreover,

I have something to get back from him.

Ki Ho,

won't I get in trouble by hiding you?

"Behold, I come quickly."

"My reward is with me,"

"and I will give to everyone..."

"according to what he has done."

The Lord is with me.

If you help me,

things will be straightened up,

and you'll be given a big reward.

Only you can save yourself.

Only after you save yourself first,

you need to ask just one thing from him.

Forgiveness.

You're here. What did you find?

The CCTV at the main gate captured him.

It's Jang Ki Ho.

It'd be impossible to find him outside.

Ki Ho knows this neighbor like the back of his hand.

Rather, you should ask...

the townspeople about his whereabouts.

Is there anything that bothers you?

Cha Young Jin and Lee Sun Woo recently act together.

It's quite annoying.

Dong Myung recognized Choi Dae Hoon in the picture.

He said he's been watching Eun Ho and Min Sung as it'd seemed...

there'd been something going on between the two.

But Eun Ho didn't tell him no matter how many times he asked.

Then,

Min Sung and Chauffeur Choi harassed...

- Eun Ho together? - The one who harassed the other...

isn't Min Sung, but Eun Ho.

He said...

he'd just scare him.

But...

I don't know why Uncle Dae Hoon died.

Say it so that I can understand.

One of my classmates was badly hurt.

And...

- he threatened me. - He threatened you?

Why would he threaten you?

The test paper you got for me.

He saw it.

What's his name?

- Ko Eun Ho. - Ko Eun Ho?

That fatherless kid?

If Eun Ho was harassing Min Sung,

that gives Min Sung and Choi Dae Hoon...

a motive to harm Eun Ho.

But...

why did Choi Dae Hoon...

bring Eun Ho to the hotel?

Eun Ho being attacked and falling from the roof might not be related.

Why did you come all the way here...

to tell me all these?

If Min Sung was being bullied by Eun Ho,

why didn't he tell his parents or you?

Is Min Sung a student that would let Eun Ho bully him?

There must've been Min Sung's fault...

that only Eun Ho knew about.

So...

you want me to find that out, right?

You said you want to know what happened to Eun Ho.

I'll excuse myself.

Ms. Cha.

Are you asking me for help?

No.

I'm going to reveal the secret of Min Sung as a detective.

As a teacher,

you'll decide on your own which choice you will make.

Hey, you're late.

Let's see.

This guy tried to buy it,

and this guy tried to sell it.

Do I know them?

He's our regular, and he used to work for you.

- He worked for me? - Doo Seok.

Bring me a cold drink, will you?

- You... - Doo Seok.

- Yes. - You can go home now.

Yes, Doo Seok. You can go home now.

That's okay. I want to see the faces of these scumbags.

I'm getting thirsty.

- Hee Dong. Should we drink beer? - Yes?

- I'd love some beer. - White wine for me.

White wine it is.

I'm fine.

Let's eat.

Fine. Eat this one.

Thank you.

What is it?

It's delicious.

Slow down then.

- I can do it. - Wait.

I think I found it.

SBS E11 'Nobody Knows' "School Exam" -♥ Ruo Xi ♥-

Here's your white wine.

- Thank you. - Beers for us.

And for you...

What's your plan?

I'm thinking.

Just let it slide. The police are after them.

It'll be troublesome if things go wrong.

And we should focus on finding Jang Ki Ho for now.

- Am I wrong? - Sea squirts don't have brains.

- What? - I mean,

they do have brains at first.

But when they're fully grown,

they find a safe place and eat their own brains.

That's gross.

Sun Ah,

I don't want to live as a sea squirt.

Sang Ho.

Choose just one if you have to. I'm tired.

Sure.

Shall we?

Which one will it be?

- Yes. - I think we found the trafficking.
