One of the suspects had mixed...
...Aioken poison in the drink
but the man began to gulp...
...the drink without any suspicion.
He was twirling in pain
vomiting white foam.
Suddenly...
What's wrong?
Hey, Teu-In. Teu-In Tak.
What's wrong with you man!
What? What is it?
What is it? Get out of the way.
What's wrong with him?
What happened?
Don't know. He just fell.
Hurry. Call for ambulance!
Yes, sir.
A person passed out.
This is Insu High School.
Yes, sir.
Hey, you. What are you doing?
Can't you see he's passed out?
Hey, Teu-In.
Open your eyes.
What's this fuss!
Teacher, what happened?
- You, did you call?
- Yes, they're on their way.
Teu-In! Come on!
Snap out of it.
Are you alright?
Are you alright?

Two weeks later...
Teu-In's dead.
Really? He's really dead?
That's what I said.
- Teu-In's dead.
- Teu-In's dead?
For real?
- Come on!
- If you're lying you're gonna get it.
That's why no one was
allowed to see him.
My God. He wasn't
that nice but still.
I can't believe
that he's really dead.
Does it make sense
that he's dead?
Did the principal said that?
What? So the school will close?
One wasted life.
I envy him.
So I don't have to think
about suicide and all.
How can you say that now?
Yo, Do-II kwon.
Are you calling it a day?
Yeah. I'm beat.
Try to run regularly.
And avoid watching those
things at night, huh?
Ah! Jung-Hoon!
Jung-Hoon! We love you.
Hey, hey. Is it them again?
Wave and make the girls happy.
Show them your smile.
Cute little gals.
- Jung-Hoon!
- Jung-Hoon!
- Jung-Hoon!
- Jung-Hoon!
What?
Call me. I'm Do-II.
- What is he?
- Is he sick?
Looks like a tadpole.
- Just a geek
- What did he do?
Gosh... he gave me his number.
You read them all?
- You stayed up all night again.
- Yeah.
Got any other book?
Nothing.
You're worse than me.
Umm... how about reading romance
like other girls your age?
Who do you think killed him?
Teu-In's case.
Why do you think that.
The principal clearly said...
crime
butchers innocence
to secure a throne
and innocence struggles with all its
might against the attempts of crime
Robespierre.
Urghhhhh.
Yup, you're one tough girl.
A curtain witch.
Everyone freaked out the
moment they saw me.
Are you alright?
What happened?
Can't you see?
General Gae-Sun...
Why you curtain witch.
Got any new books?
Are you really alright?
Waist
Dude!
Move your ass like this...
Definitely hot.
- Let me see him, too.
- No, he's mine.
- Don't even think about him.
- Why, is he yours?
- He's mine.
- Why?
We're gonna get married.
Well, I've known him
for years.
- Don't kid yourself.
- Look. Just look at the picture.
Hey, Tae-Gyu kim!
What was that?
Sick pervert.
Did you wear your
mom's underwear?
Jung-Hoon! Jung-Hoon
Do something.
Give it here now.
Delete the picture.
What?
I said delete the picture.
Whoa. What did you say?
What?
What did he say?
Who do you think you are,
shit-head to tell me what to do.
Are you her man
or something, shit-head!
Mad dog! Mad dog's coming!
What's all the commotion?
What.
Did you fight?
Huh?
I asked you if you fought?
Answer me!
Get up.
Does this place look like
k1 ring to you?
Does it look like a k1 ring
for fighting!
Answer me!
I said answer me!
You damn...
You will be doing service
for the class.
Jung-Hoon clean the class
for a week
and Tae-Gyu, since I love you
for the year.
Did you get that?
Answer me!
Yes, sir.
Shit.
Urgh, That Tae-Gyu kim.
Hey, Do-II kim!
What're you doing there?
Shh! Hurry hurry
She's a killer.
You wanna be like Tae-Gyu kim?
- No way, man.
- Uh?
You know that girl in your class
with hair like a curtain
like this.
Hey hey she's coming out.
I knew of her quality
way ahead of time.
Geeze... her body's a killer, isn't it?
Yo, Jung-Hoon.
Hey!
What're you doing?
Get down!
? Hey listen Mr. Boy
With your sexy lips
? Now tell me love
you feel for me
? Come on like a man
? Words filled
? with boring pride
young men with bright future
? thoughts that
move one's heart...
Stop it, punks!
- Hey, Tae-Gyu.
- Tae-Gyu.
You alright?
I just wanna kill all the
filthy dogs.
My God
Didn't we barely save Teu-In
who was dying that day.
Didn't we? My God.
I got the doctor to keep
his mouth shut.
I said that Teu-In reacted to
peach allergy.
But how can a student
drink a beverage with poison
at the school?
Doesn't this mean that someone
has a grudge on him
and wants to kill him?
Am I wrong?
Am I overreacting?
I will investigate carefully
so no one will suspect.
Do it right, please!
And do you know what
day today is?
School commissioner is
visiting our school.
If things go wrong,
this school will close down.
Am I wrong?
Ratio r of geometrical series...
Pervert! Do you enjoy
sneaking around?
Da... Da-Jung Lee?
Then, there're others?
I must not be the first victim.
I didn't sneak
It just showed.
And to be honest
I didn't enjoy it!
You didn't sneak. It just showed.
And you didn't enjoy it.
What's with you these days? Huh?
Fighting and text messaging
during class.
What is it?
I'm the one who used...
Who's Do-II?
You saw with Do-II?
What did you see.
I don't like it.
You want a nice bite?
Huh?
So pathetic...
- Is your class over?
- Yes,
Mr. Guk-Man, you got to find
a nice lady and get married.
Are you seeing anyone?
Why? Do you have
a lady for me?
I know a load of ladies.
That's why I'm the ladies bank.
Girl bank...
But, Mr. Guk-Man.
Yes.
If you want to date and get married
you got to invest in yourself.
Invest?
What's that you're wearing?
Is over ten years, right?
Take that old style to the grave.
Any normal women
will run away from you.
Mr. Byung-Soo.
Do you know why students
call you MBC?
Margarine, butter, and cheese.
Totally greasy.
Totally greasy?
Which son-of-bitch...
Which son-of-bitch said that?
Which one?
- Sujin, hurry.
- Ok.
You got a damn strong stomach.
Of all girls, you sneak
on the curtain bitch?
Wasn't it? The curtain.
So did you get a good look?
You didn't, didn't you?
I got a picture of her.
Wanna see? Huh?
Perverted punk.
You mad, man? Huh?
So, what you gonna do?
You're gonna kill someone.
Look at those eyes.
Wanna kill me?
Do you wanna kill me?
Go ahead.
If you can, punk.
Get out.
Whoa.
You must really like curtain.
Uh-oh. I already
got her.
Jung-Hoon!
Go ahead!
You're not worth it.
Today is the our son passed.
Come home early.
You're out.
What? You didn't go to class?
It's PE time and you put
me on class duty.
Don't you know that the school
commissioner is coming today!
Go to class now!
Yes.
Jung-Hoon Han!
Yes?
If you get tired of things
just run.
No matter how hard it is
clock still ticks.
Ah... right.
Geeze. You really got me.
Hey. Tae-Gyu kim.
Hey!
Hey. Tae-Gyu kim.
Welcome.
Nice to see you.
Please.
No... It wasn't me. I didn't kill him.
No. No. No.
Da-Jung, it wasn't me.
I didn't kill Tae-Gyu.
I know.
Commissioner, as you can see
students are the utmost importance
in our school.
That's what we believe.
You know?
Ok. Let me call 119.
And our school's pride number one
in nation Jung-Hoon Han
is the result of perfect team play
between faculty and
the students.
Number to 119.
Even at this moment,
our students are taking
one step closer their dream.
Hey! What are you doing!
Face it.
You are number one suspect
to the murder of Tae-Gyu kim.
I understand.
Since we don't have much time
let's look around the school first.
Of course.
Let's then...
Is your fingerprint on it.
Huh? Yeah...
I wonder who fought with
Tae-Gyu the last?
Well, it wasn't actually a fight.
Suspect, victim, and witness
Then the criminal?
You just said I didn't kill him.
It's not me.
I didn't kill him!
Do you think people will just
say, Ok we believe you?
Now, make your choice.
What?
Either get arrested
as a murder suspect and endure
all the questionings or join me in
finding the killer in the fourth period.
And reborn as the school's hero.
How can we find the killer
when we don't know who did it.
Plus you're not a detective...
Can I trust you?
Listen.
The killer knew
there will be blood
so he changed into raincoat
and students slippers
and approached
Tae-Gyu from the back.
Wait...
Why students' slippers?
Are you really first in nation?
That's to corner you as the killer.
Oh
The killer approached Tae-Gyu
from behind,
covered his mouth and
stabbed his chest and
to make it look like you did it he
stabbed several times from the front.
So the blood
splashed to the front
and got on the net book
that was laid on the desk.
And I'm... positive that
you're not the killer.
How?
There is no trace of splashed
blood on your shirt.
Yeah. I told you it's not me.
But, Tae-Gyu's net book's gone.
The killer is still in the school.
How do you know that?
If he left the school
after the killing
he would be the suspect.
It's probably someone who knew
about you and Tae-Guy's recent fight.
You're not worth it.
A student?
Or... teachers?
Then the killer wouldn't
have thrown away
the raincoat and the shoes
in the area.
Oh... now you're thinking.
So, how about it?
Finding the killer
in the fourth period?
Yeah, let's find the killer together.
Then... take it off.
Take what off?
Do you want to tell everyone
that you killed him?
Oh...
Hey! What are you looking.
I'm not sneaking.
It just showed.
Honestly... I didn't enjoy it.
Go wash.
Uh?
If you're done changing,
go wash.
Oh... yeah.
Why would the killer take the
inet book and cell phone?
Are you done washing?
Yeah.
We got less than 40 minutes.
We need the contact list
of all students.
Then... the computer lab?
It was General Yi Soon-Shin
who I wanted to have
a cup of tea with.
And he was the person I wanted
to kill the most.
Who dares to run during class?
It's locked. What do we do?
Wait.
Hey, where did you
learn to do that?
Several readings will do.
Uh? There's password?
Isn't the mad dog
the computer teacher?
Wait
Try ROTC29.
Bingo!
Let's download it.
Please leave a message
after the beep.
It's done.
Don't worry.
Just trust me, alright?
I can't live... a moment without you.
You know that?
Text message me when you get
this message.
I will protect you with my life.
I'll see you later.
Love you.
I will have every student
text message me.
I'll make it look like
the school commissioner sent it.
No one knows
my number anyways, right?
Curtain head.
Text me if you know any
teacher or student late to class
this is regarding school inspection.
Need your support, School Commissioner
Da-Jung...
why are you helping me?
Don't disturb me.
I'm busy.
Thanks.
Now look.
Article 8 shows the social
aspect of Old Joseon.
Two, two, three, four.
Five, six, seven, eight.
Next motion.
I don't see Da-Jung.
She got out earlier
and must've went back to class.
Who gave permission to go
to class.
Go and bring Da-Jung.
Yes, sir.
Two, two, three, four.
Why me.
- Run!
- Yes.
Message should get there.
Considering all possibilities
it's likely to be a teacher
than a student.
You mean a student late to class
ten or twenty minute late
can't carry in a strange bag?
Hey hey, you there.
Then if it's a teacher?
It won't matter if he's late
to class after the killing
and if he doesn't have class
he can just go to the faculty room
and leave the bag in his drawer.
Then what's next?
The faculty room.
Da-Jung Lee.
Da-Jung, the PE teacher is...
Sick, what are they doing?
Why in my class.
Shit.
Where did she go?
We don't have much time.
Yeah, let's go.
- It's the computer lab.
- Really?
Our computer lab
runs on academic purpose only
and is locked
when there is no class.
Kids can see so many
things on-line.
Yes, they can.
Mr. Han, please open the door.
Yes, sir.
It must be class time.
Ah, yes...
Teacher!
What is it, Jung-Hoon?
The commissioner
wants to see you.
The principal told me to get you.
Really?
Where are they?
Uh... but the dumpster.
What's he doing there?
I think he wants to
talk about the school sanitary.
Yeah? That's quite far.
But why are you not in class?
I got called on, too.
You know.
I'm number one in the nation.
Yeah... right.
Ok. You may go.
Yes.
Sea in a big picture is
made of gulf and peninsula but
there is also rocky sea...
rocky sea is the land that's
protruded to sea
and is open to strong waves
therefore marine animals...
Hey! Crazy bastard.
If you are the school commissioner
I'm Brad Pitt.
Why that Jung-Hoon!
Everything's deleted.
MBC probably deleted everything
that can be an important evidence.
You!
What're you doing?
There's a tool that recovers
recently deleted files.
All we got to do is...
Hey! Jung-Hoon Han!
Bring that net book and cell phone.
You should know better than take
someone's properties.
These aren't yours anyway.
What?
Didn't you hear me?
Punk.
Hey, you punk.
Bastard.
Come here.
Hey...
Stop right there!
Stop!
And living and non-living organisms
have symbiotic relationship.
You two stop!
Stop!
Stop!
There's lithium, natrium, calcium,
magnesium, aluminum in gold.
Now we take the substance
in gold and...
Call me! My name is Do-II.
Jung-Hoon's acting
little strange today...
Aren't you his friend??
Let's look out for him...
That flying nightingale
why you two are lovely
To where would this
lonely body fly to.
Now, let's take a look.
Jo-Ga Hwang is recorded in
Part 4 of traditional korean poetry
and Book 13 of Samguksagi
Teacher!
I'm sorry but...
I have a stomach ache...
Go. Get out.
Thank you.
Stop!
Punk!
Stop!
Yes, the school is very big.
Have some cold water.
Hey, hey, You!
What. Who were they?
Ah, yes, they're our
school's track team.
And their teacher.
Jung-Hoon.
Jung-Hoon couldn't have...
No, Jung-Hoon.
Stop!
Stop, punk!
Wait.
Shit.
Those rats...
Where did they go?
Ah!
Da-Jung, Da-Jung
What's wrong?
My leg fell asleep.
Are you alright? Does it hurt?
School commissioner?
Don't shit me.
Uh... message!
What's it say?
Something's fishy...
It stinks...
Check out somewhere else...
head of the school
Nothing.
Does it still hurt?
- Get on.
- What?
Get on.
No, I'm heavy.
Hey, Da-Jung.
You can't walk in like that.
We can take a break
once we get to the roof.
Hurry!
Alright.
Uh? A message.
What does it say?
Don't shit me... drop it.
Why?
It's nothing.
Uh? Are you alright?
Why are you running around
during class?
Well... I had to go
to the bathroom.
Anyways, did you see
Jung-Hoon on the way?
No, why?
Get to your class, punk.
Why this punk...
Sorry.
I'm fine. It's nothing.
How's your leg?
I think it's alright now.
Hey, punk!
Give me that...
net book!
Why do you need this?
You are mistaken.
I didn't do such a thing.
We'll find out...
after the investigation.
Investigation?
Just...
hand me that net book.
And we'll talk about it later.
Just hand it over!
This net book!
Is an important evidence.
Gosh. You got it wrong.
It's not like what you think.
I just...
Just give me...
that net book!
I'm sorry, teacher.
You punk.
Net book...
Do-II
How did you get here?
Go!
Where?
Run away! I'm your friend
so I can understand.
Go! Get out!
Run away!
Hi!
Uh? You are...
Ms curtain?
Uh? What is it?
Isn't this MBC
and Ms Hong Ju-Hee?
Isn't she married?
Uh? I think it was
MBC's cell phone.
You said everything's taken care but I'm
worried... Is everything alright? Juhee Hong.
- MBC and Ms Hong...
- What?
Stay.
MBC and Ms Hong were going
to the motel
and Tae-Gyu saw them.
Tae-Gyu got the sight
on his cell phone camera
and made several threats.
We caught the killer
in the 4th period.
Nice job, Da-Jung.
And Do-II, thanks a lot.
You were a great help.
Yeah! We did it.
We caught the killer
in the 4th period.
We... did it.
Now, bring our school's pride
Jung-Hoon Han.
He acted strange earlier
but talk to him and bring him.
- Yes.
- Hurry.
Then... it's all over?
Is MBC really a killer?
Da-Jung.
I'll go back to the class
and open the curtains.
Do-II, keep that net book.
It's a very important evidence.
- Don't worry about it.
- Thanks pal.
Jung-Hoon!
Nothing... see you later.
Is it Jung-Hoon?
Teacher...
Being number one
is hard, isn't it?
Can't hang out with friends
and no time for yourself.
Can't get enough sleep.
I know it's hard to meet
everyone's expectation.
Uh... teacher.
My son died today
many years ago.
Had he been alive, he would've
grown to be a fine young man.
This is all my doing.
I killed Tae-Gyu.
You didn't do anything wrong.
I'm mad dog, after all.
You and Tae-Gyu were fighting
and I tried to stop you two
and killed Tae-Gyu
by mistake, alright?
Jung-Hoon.
A moment's mistake can
ruin your life.
You have a whole
future ahead of you.
I'm fine.
I'm fine so when the
forth period ends
you just quietly
just quietly quietly!
Stay quiet!
I killed Tae-Gyu...
What is it?
Da-Jung.
I knew it was too easy.
Hey, where's Da-Jung?
Yo, Jung-Hoon. Jung-Hoon.
How about MBC...
Do-II, wait. He may not
be the killer.
What? Not the killer?
If he was trying to make
Jung-Hoon the suspect
he didn't need to hide
the net book and the cell phone.
MBC simply took the net book
and cell phone to
hide the evidence of their affair.
Then, there was another reason
for someone to want to kill Tae-Gyu.
Who are you trying to kid!
Going behind my private life.
Tae-Gyu!
If the drink that Teu-In drank
belonged to Tae-Gyu...
You like the librarian that much?
She gave this.
The librarian?
It must be someone who has
plenty of time and accomplice.
Teu-In.
I have something to
ask you.
Who... are you?
The curtain?
He always talked about
Sang-Mi at the library
that she's pretty but a bitch.
And if I asked him if
he knew her well
he laughed like a mad man.
I think she's pretty...
He's taste for girls
is way strange.
Make the deposit as
promised by tomorrow, got it?
Da-Jung?
You look so pretty like that.
But...
isn't it class time?
Who do you think is the killer?
Who do you think?
Mr. Guk-Man was late to class today
and ended early... He's such a loser.
What're you doing here!
Isn't it PE time?
What're you doing here?
This this...
Oh, apple.
Da-Jung.
Who do you think
is the killer?
Crime
butchers innocence
to secure a throne
and innocence struggles with all its
might against the attempts of crime.
Robespierre.
When I saw this
in my dad's study
I was just 9th grade.
Even if you were a poor college
student, you film this trash?
Why my dad? Why?
And you have the nerve to
show up!
Why... did you film this trash!
Do you know what loneliness is?
You return home all tired
and the only thing that greets you
is the flickering light.
It's worse during the holidays.
Do you know that?
It get less Lonely being
at school teaching.
But what I really can't stand is...
even the ugly ones
take me as a fool.
Teacher, it's not too late...
But one day
an angel appeared in front of me.
She's always nice and good to me.
Goes to the movies with me
and holds my hands...
It's so pretty.
And I couldn't forgive the
punk who troubled her.
I want this happiness...
to continue.
Be... be... be... behind you!
Kids! Come out now.
Or I'll get angry.
You shouldn't be lingering
in the library.
How did you know that
I was in the library?
Li (for Library)
Run!
Thank you.
Mr. Guk... Guk-Man.
What are you doing?
Mr. Principal!
What's going on?
Will you explain? My God.
Teacher.
It's... over.
It's... all over.
H... Hi?
Yeah, Hi!
How... are you?
Are you feeling alright?
What do you mean...
I can't think clear.
Does... it still hurt?
You know in gangster movies
they get stabbed and are fine.
That's... really a bullshit.
If you get stabbed
it hurts like hell.
You are exaggerating...
Were you studying?
Yeah... but I can't seem
to concentrate these days.
Then... don't.
Jung-Hoon!
This week's class duty
Jung-Hoon Han, Da-Jung Lee
Director Sang-Yong Lee
