I asked you.
I told you to stop.
Don't cross the line, all right? Know when to stop.
What?
Me? I'm like your guardian angel who just woke up from a nap.
Unconditioned reflex.
If an object suddenly appears, you instinctively shut your eyes.
It's an innate response to stimuli.
Knock it off, you nutcase,
or you're really going to get hit.
I said knock it off.
Don't tell me what to do.
What are you doing?
No! Put it down!
What are you doing now?
Jeez, Teach.
I was trying to stop them from fighting,
and I was almost put in danger.
I am really sorry.
Quick! Apologize!
Now!
WEAK HERO: CLASS 1
JEONGJIN SEOUL HOSPITAL
Yes.
Yes, we just got to the hospital.
Yes, we'll talk it through.
Don't worry.
I'll let you know.
What were you thinking?
Ma'am, please calm down.
Why are you alone? Where's your mother?
I'm sorry.
I don't need your apology. Just bring your mom.
I have no mom.
There's always something.
I'll be sending you to juvenile detention for sure!
Got it?
Yeong-bin made another kid
put this on my neck.
What is that?
- That's-- - A drug.
It's a drug.
What's this fucking bullshit?
You have proof?
Fuck, can you prove I did it?
You still don't get it.
This is your bag, right?
FENTANYL PATCHES
You do realize this isn't just a school violence issue now?
I think Yeong-bin should transfer to another school.
If this gets out…
Well…
Let's just let it slide.
Hey, Si-eun!
What's wrong with your hands?
I got hurt in gym class.
Let me see.
Did you pass out again?
No, I don't do that anymore.
Hey, kid.
Now you're fighting with your classmates?
Hey, it's fine.
Men are supposed to fight as they grow up.
I've been there too.
It's not like that.
Did you at least get to throw a punch?
Fine, I get it. Rest up.
Puberty, huh?
Hey, fucker.
See me after class.
You caught me off guard, you bastard.
You're gonna fucking die today.
Let's do it now.
Crazy asshole.
That son of a bitch. Seriously.
- Should we stop them? - Looks like a fight.
You guys
aren't good at learning, are you?
The fuck you say?
If your memory is bad…
you need to review more.
Pavlov's dogs experiment…
Ring the bell.
Give a treat.
The dog salivates.
Ring the bell.
Give a treat.
The dog salivates.
Only ring the bell.
Let's stop.
I'm asking you.
Do me
a favor.
He's totally fine and not hurt at all!
Hey, Si-eun, how'd it go?
Did you totally lay out those assholes?
Do I know you?
Are we close?
What? Where did everyone go?
I told you to watch yourself.
What is it?
Nice chance for a nose job.
Who was it?
A classmate.
How much will you pay me?
How much do you want?
Fuck, are you rich?
I wish I had your dad.
"Please help me."
"Sir."
Say it.
"Please help me, sir."
Please help me.
Sir.
How come we keep crossing paths?
Were we married in our past lives?
Where are you going?
Home.
What?
Home!
From cram school?
Yeah.
I'm sorry.
Now you're sorry?
If you are, then buy me some food later.
I'm off. See you later!
I'll take these two.
Delivery's here!
Delivery is here.
- How about some candy? - Yes, please.
Keep it quiet, okay?
BYUKSAN HIGH SCHOOL
FACULTY SHOWER ROOM
It's lunch break.
Yeah.
I'm good.
I'm buying.
What's with that look?
I won't eat.
I didn't expect anything fancy,
but I've already paid for my school food.
Then don't eat.
Bon appétit!
So…
why do you sleep at school?
I come here right after work.
If I go home, I'll oversleep.
Grandma says even if I don't make it into college, I shouldn't skip school.
Do you like listening to music?
You always have earbuds in.
It's rude.
- I get annoyed. - What?
I wear them so people won't talk to me.
You're fucking weird, man.
Look who's talking.
Hey.
Why's Si-eun not in trouble?
I heard
that Yeong-bin had fucking fentanyl.
- Really? - You're exaggerating.
It's true. They're gonna cover it up and move on.
But why are they hanging out together?
I know. They're like best friends now.
Su-ho is a damn MMA master. I heard he almost became a pro fighter.
His counterpunch is fire.
Yeah, he's freaking good.

They're my crew.
He's my cousin.
A rich fucker.

Dickface.
Me?
Fucking harsh.
Hey.
When is the kid out?
Yeon Si-eun!
You're not staying to study?
You going to cram school?
Yeah.
Which one?
Daemyeong Academy.
I'm thinking of going to a cram school. How do you like it?
Should I go too?
You don't need to suck up to me.
And I won't accept an apology.
Let's do it quickly!
You spooked me.
What? Class is over?
Yeah.
I feel left out now. It's really upsetting.
- Couldn't you jerks have woken me up? - You said not to.
Did I?
Then wake me in ten.
Is this him?
Are you fucking kidding?
Aren't you guys ashamed? This is wrong.
I need to go study.
Nothing personal.
It's just business.
Hey, that's Yeong-bin, right?
- Whoa, scary. - Fucking savage.
Right, that's Yeong-bin's cousin.
Ahn Su-ho.
Ahn Su-ho!
Jeon Yeong-bin,
he's dragging Si-eun off.
Jeon Yeong-bin.
He's dragging Si-eun off.
And?
What?
No, please help.
You have to help.
I heard you know martial arts.
We aren't that close.
How close do you need to be to help?
Go find a teacher.
I have to work.
I'll pay you.
Double what your job pays.
Thank you, sir. Let's go.
Let's hurry, valued customer!
What's up? Get on.
Look out for him.
Go be the lookout.
Wow.
I'm really fucking bored.
Are you little kids?
Gil-su is calling. End it quickly.
Seriously.
His hand.
Rip off the prick's hand
so that he can't study.
Three on the left.
Beat them down quickly.
Two on the right. Conditioned reflex. Deal with them later if needed.
I need to get the drop on him.
Just end it quickly.
What is this?
Fuck!
Move.
Hey!
I'm sorry.
I underestimated you.
Out of the way.
Son of a bitch! Fuck you!
Fucking bastard! Dumbass!
Dumb piece of shit! Son of a bitch! Fuck!
Hey.
Grab his hands.
Son of a bitch.
You fucker.
Know your fucking place.
Fucking moron.
Hey, you okay?
Who's this punk?
Are you okay?
Don't leave me hanging.
Let's call it a day.
Yeah?
Hey.
Hey, grab that asshole.
Fucker!
Tap out, fucker.
You're going to die.
Hey!
Good job.
Anyways.
Aren't you embarrassed, ganging up on him?
If it were me, I'd die of shame.
Seok-dae.
What are you doing?
Do your job.
Hey.
Looks like he is embarrassed.
That's enough for today.
He's leaving.
Hey, Gil-su called.
Hurry, let's go!
Seriously?
Jeon Yeong-bin.
Stop it.
I said stop.
Let's go.
Let me see. Oh, it's really scraped up.
I really worked up an appetite.
Let's go eat.
I know a good place.
It's on you, right?
What's up? Get on.
- I need to go to cram school. - Come on, man.
You can't even muster up a thank you to your saviors?
I said I know a great place.
I'll pay, so eat what you want.
Sorry I'm late.
Oh, Su-ho, you're so late!
- Yes. - Did you eat?
- Not yet. We'll eat later. - Oh, that's too bad.
I was late because of you guys,
so help out.
You're Su-ho's friends?
Hello.
It needs to shine!
Where did you learn to wash so well?
Your mother must be so proud. Such a precious boy!
There's one more box.
You have two jobs?
I do deliveries three times a week.
Not every day.
Isn't it hard?
It is what it is.
I work as a mover on weekends.
Why?
Do you respect me now?
Welcome! Come on in.
Finish this up.
What can I get you? Take your time.
So…
about the mock test…
I'm really… sorry.
Yeong-bin threatened me.
And I really didn't know what it was.
I know.
It's fine.
Damn, I'm starving.
Is it better that way?
- To die for, yeah? - Oh, it's hot.
So hot!
Okay, then!
Si-eun, one for you too?
Eat it in one big bite to really taste the meat.
You eat it.
Man.
No one's ever regretted listening to me.
Say, "Ah."
"Ah!"
Did you wash your hands?
Dammit.
This dude knows nothing.
Hands make the food taste better.
It's fine. "Ah!" Come on.
"Ah."
How is it? To die for, right?
Yeah?
Right?
It's really tasty.
Right? You'll have to come back!
- Can I? - Yeah.

I'm a real estate agent, but--
Next, I'm going to talk about indeterminate equations.
These are a core part of high school mathematics,
and it's a concept used in all areas of mathematics.
We'll take a closer look today.
Now, indeterminate equations.
So why do we call this an indeterminate equation?
It's an equation that doesn't have a fixed solution.
Why is it like this?
There isn't just a single solution,
and it's hard to say that one of them is the answer.
To solve this equation…
Fucking bastard.
