So you add this to C and then do cosine A...
Cosine A?
Cosine A...
This is cosine...
Keep it down!
Quiet!
Okay then...
-Stop there! -What's your problem?
Hey!
Stop there!
Okay...
And the cosine of A...

Have you eaten?
Jihye, did you miss mom?
When I think about it...
The greatest dilemma of my life...
...has always been whether to go or not.
Let's go with mom, okay?
She doesn't want to.
It's only because you've scared them.
I scared them?
Jihye.
Are you scared of daddy?
You're drunk all day long. Of course she's scared of you.
I'm their father.
That's nonsense.
A father should act like one.
Jihye, come to me. Come here.
-Come to mom. -Where are you going?
Let go of her!
Where are you taking her?
Jihye! Jihye!
Jihye...
Jihye.
Are you going with her?
Tell me. Do you want to go or not?
Huh?
Yeah. Jihye, you decide...
Should I go or not?
Mom or dad?
The choices I had to make were...
...much more serious than what flavor ice cream I wanted.
It was like do you want blue tissue paper or red tissue paper.
Will you go?
What?
Will you go to this?
So sorry.
Where were we?
That not everyone can go.
That's right.
Not everyone can go to this.
It's only to those who excel in English.
They feed you and give you a place to sleep for a month.
2,000 dollars is just plane fare.
Talk to your parents about it...
...and tell me as soon as possible.
-Yes. -Yes.
Jihye.
Yes?
We always go on about public education but these chances don't come often.
So try your best to go.
When it comes to speaking,
you can't beat girls like Seongyeon.
You can't help that.
Oh, dear. What am I saying?
It's just that I really want you to go.
Go on now.
Thank you.
No thanks. I've got this.
What is that?
Mom told me not to eat from the cafeteria.
She's too fussy, right?
Do you want some?
It's okay.
Oh, yeah.
Jihye, are you going to this?
I don't know yet.
It is extremely affordable.
Is it somewhere like the Philippines?
It's England.
England?
Oh, England!
England...
Wasn't that your dream?
What dream?
Do you want to go to this together?
Let's consider it a cheap holiday.
You're going to your auntie in the US.
Forget it. I'm sick of the US.
Let's go together.
Let's go.
We're going, okay?
I'm going to tell my mom.
So noisy!
Me?
No.
The cicadas?
Shouldn't the government do something about them?
They're not even harmful.
They are harmful.
They cause noise pollution.
I'd prefer cockroaches.
Oh, God.
My friend parked it there.
This is no valet parking.
-Why leave his keys? -I don't drive.
I'll give it back to him. Give them back.
Tell your friend to come and get them himself.
Stop talking nonsense.
I said no motorbikes allowed.
Kill me and take it if you want.
You don't even care about me. Why cause a fuss now?
I won't tell you again.
Tell your friend to come and get them.
Yes, chief?
Yes, I can do it.
By 8:30?
To the convention centre?
Okay.
010...
6998?
Okay, I'll see you tomorrow.
What's this?
Mom.
Do you have 2,000 dollars?
2,000 dollars? For what?
What a waste.
Why does a high schooler need to go abroad?
That's not it.
Kids even younger than me go on these.
Can't you turn that off?
You have to pay for everything anyway.
Look, it's almost for a month.
2,000 dollars is pretty much just airfare.
In university they send you on these for free.
But to get into university...
I have no money because of graduate school.
Ryu Jihye.
Did you leave money with me? Why get mad?
I didn't get mad.
You've done fine without things like this.
Yes, I have so far. But I can't anymore.
What's the use in me doing my best?
How can I beat kids that have been traveling overseas since they were little?
Some families take out loans for their child's education.
You're so busy with your studies you don't even give me a chance!
Your application forms.
Don't forget the documents written here.
It's not a program run by our school.
So they're quite strict about due dates.
-Yes. -Yes.
"I want to experience the wider world and expand my knowledge."
Go away.
Move, I need the computer.
I have to do this now!
Get off by the time I've had my shower.
I'll kill you if you don't.
Jerk!
Hey...
Cockroach! Cockroach!
-Look, cockroach! -You kill it.
Please kill it for me.
Please. Hurry up.
-Move. -Hurry it up.
-Wait. -Come on.
What do I get in return?
You can use the computer. Go and kill it.
The cockroach doesn't make a sound even to the point of death.
It's fortunate for both humans and cockroaches.
Since they make no noise, they can coexist with humans.
If cockroaches cried like cicadas...
That cockroach was as big as my hand.
You saw it, Jihye. Tell her.
I wondered why you were awake at this hour.
Talking about cockroaches at the table.
We need to call the exterminator.
It was just one cockroach.
Why call the exterminator?
One cockroach means there are thousands.
They're all hiding around here.
Do you know how sly they are?
-Just tell them to keep hiding. -What?
What crap is that?
How dare you?
Don't speak like that to your mother.
Dogs go woof woof. Cicadas buzz.
They all make distinct sounds.
But cockroaches don't make a sound.
They must've evolved that way to survive.
It's only a bug.
That's enough. Just eat your food.
If they made a sound,
it'd be easy to know where they were.
This is why we have bugs.
How did humans survive?
They make the most noise of all.
You brat.
-Don't eat then. -Even a dog wouldn't eat it.
How dare you!
Why are you so rude?
Jihye, why aren't you wearing your uniform?
I told you it was our school anniversary.
I have to make a passport.
Really?
I'll give you my card later. Use that.
Money doesn't solve everything.
Underage kids need a guardian.
That's during my works hours. How can I go with you?
It's okay. You're all grown up. You don't need a guardian.
Just call me if there's a problem.
How did they survive...
...without becoming extinct?
So you need your father to come with you since you're on his family register.
But...
It's been over 10 years since they divorced.
And I've lived with my mom this whole time.
I haven't even contacted him.
I understand your situation...
But according to the records your mom is just living with you.
Without your father's consent, I can't issue your passport.
Actually it wouldn't be an issue, if your father had passed away.
Mom.
They say I need a guardian on my register to make a passport.
What does that mean?
I'm on dad's family register.
So I can't make a passport without him.
We don't even know where he is. How can we get his permission?
I already told them.
-They say it has to be... -Let's talk at home.
Mom... Mom!
Ryu Jihye!
What on earth is going on?
Mom...
Don't you know dad's number?
Not even his address?
Even the loan sharks don't know that.
Geez...
Why did you put me on dad's family register?
He said he wouldn't pay for child support unless I did. What choice did I have?
Didn't you know this would happen?
Just wait a few more years.
When you're an adult, this won't matter.
What about my passport?
It can't be helped.
It's not like we can change the law.
Mom.
Doesn't dad have family or siblings?
Or even friends or a work place.
You've never cared about your father and now you ask those things?
What choice do I have?
I can't make a passport without him.
Forget about your passport.
Will you die if you can't go overseas?
He's of no help to me.
It'd be better if he were dead.
Ryu Jihye!
Mom was right.
I've never once cared about my dad.
Much like a cockroach,
he was ever silent in my life.
Father, fatherhood, these words
never existed in my life.
And that never affected my life.
However...
Someone who's been haunted by a cockroach,
never forgets that experience.
What are you doing in my room?
What are you doing?
-Cockroach... -What?
-I came in to catch a cockroach. -Where?
-Right there.
-Where? Where? -Right here.
-Where? -It's over there.
Hey, kill it first.
Hey, get out here.
Kill it! Hey!
I can't, it went under the bookshelf.
You catch it. Hey!
Get out here.
Hey, kill it!
Hey!
This is the service center.
Is that the Dongnim Service Center?
Yes, that's right.
Does a Ryu Jeongcheol work there?
Can I ask who you are?
I'm Ryu Jeongcheol's daughter...
There's no one by that name here.
Hello?
Get out here!
You're dead meat.
Get out.
What do you mean?
Why can't you make a passport?
Thing is...
-It's a little complicated... -Forget that.
How will you go overseas without a passport?
Don't you know the documents are due tomorrow?
Are you sure you even want to go?
At least bring a receipt for your application for a passport by tomorrow.
Understand?
Teacher, the thing is...
-Oh, hello, ma'am. -Hello.
You're here on management committee work.
-Yes. -I'll escort you.
Jihye? Ryu Jihye?
Excuse me? Yes...
I've heard so much about you.
Sorry, but who are you?
I'm Seongyeon's mom.
Wow, how did you recognize her?
I was a little unsure...
But I saw her name tag.
I've heard so much about her from you.
I acted like I knew her.
You were shocked, right?
No.
I would've done the same thing.
Since you're the first friend she's had, she's always talking about you.
I never did that.
I've heard about your situation.
Your family register issue is no problem.
I'll sort it out so you can make a passport.
I've spoken with the teacher. So don't worry too much.
I don't know how to thank you.
There's no need for that.
We were worried about Seongyeon going alone.
It'd be good for us if you went with her.
How come you're so mature, Jihye?
You don't seem the same age as Seongyeon.
Are you the oldest child?
No, I have an older brother.
Really? You have an older brother?
How old is he?
20.
He must be in university.
I should ask him to tutor Seongyeon.
Yes.
Let's have lessons together.
Your mother is really amazing, Jihye.
She's raised such wonderful children.
That's right.
When I take on violence and assault cases,
most kids come from single parent families.
You've been really raised well.
Let's eat.
Eat up, Seongyeon.
Taste the salad.
(Mom)
See you.
Bye.
Later.
-Hello? -Why didn't you pick up?
-Are you home? -No, I just got here.
Do you know what happened today?
I'm going insane because of your brother.
I'm at the police station.
How come?
Why do you think?
He assaulted someone.
Again?
I'm going insane.
I think we'll be late so go to bed.
Have you had dinner?
-Excuse me. -I ate.
-Yes... -Seongyeon's parents...
I'll call you later.
Hello?
You're home?
What happened? Didn't it work out?
They say the other party started it.
But your brother beat him to a bloody pulp.
Does he think he'll go to juvie for the rest of his life?
So what's going to happen?
We have to reach a settlement, what else?
At least they're not pressing charges, right?
It's better than going to court.
I wouldn't care if it were a few dollars.
Yes.
This will cost less than paying for a lawyer.
Did the other party ask for that much?
Forget my graduate school, we can't even afford a rice cooker now.
Then...
What about my program fees?
You can't go because of your passport anyway.
I can make a passport now.
Seongyeon's parents are helping me out.
It can't be helped now.
We can't let your brother be an ex-con.
Gosh.
I'm really tired. Let me get some rest.
If he's committed a crime then he's a criminal.
What?
Why does he cause all the trouble and I suffer the consequences?
Geez.
Ryu Jihye, are you insane?
Why are you being a problem right now?
You're the one who cause so much trouble!
She's doing it again. Open this door.
-Open the door. -What are you doing?
-I'll kill you. -Stop that!
-I swear I'll kill you. -Are you crazy?
Get out here.
Hey, go away.
-I'm going to kill you. -Be quiet!
Go to your room!
Teacher.
Oh, what's the matter?
I...
I don't think I can take part in that program.
What?
Are you kidding me?
No, the thing is...
Something came up at home.
Something came up?
Exactly what happened?
I...
I can't pay for the program fee.
I guess it can't be helped then.
Okay.
Get going.
Why? Did the teacher tell you off?
She just said okay.
Oh, by the way...
Please tell your parents I'm sorry.
They put a lot of thought into it for me.
It's okay. You don't need to be sorry for anything.
Did something happen at home? Is it really bad?
It's nothing big.
Just...
My mom has to use that money elsewhere.
Is it because of money?
Then I'll tell my dad and...
Am I acting like a brat again?
I just really want to go with you.
I know.
I'm sorry I can't go with you.
Jihye, what time do you finish?
Want to eat out with mom today?
Hey, Ryu Jihye.
Who's that?
-My sister. -Sister?
She looks nothing like you.
How old?
What's her name?
-Let's just get going. -Okay.
Wow, she's pretty.
Hello?
Hello, is this Jihye?
Yes, who's calling?
Jihye, it's me, your dad.
Has my daughter been well?
How many years has it been? Hearing your voice, you've all grown up.
How...
How did you find my number?
I heard you called my friend.
I called the number that was recorded.
Is something up at home?
It's nothing.
I just wanted to know how you've been.
The heavens finally answered my prayers.
What?
I left you and your mom...
...because of debt and squandered my life.
I went from here and there,
and my health deteriorated so much...
...that I asked my friend for a favor to work at his shop.
You know the Dongnim Service Center?
I'm living there at the moment.
Are you sick?
I...
Jihye, I...
I have liver cancer.
Are you listening?
Yes.
I've been punished for all my wrongdoing,
so I wanted to die with my family beside me.
I prayed that so much.
And then you called me.
Thank you so much.
Thank you, Jihye.
Yes.
Please tell mom to live with me again.
Okay?
That's what you want too, right?
You want to see me, right?
Yes.
Did you sleep early last night?
I saw you didn't even eat dinner.
The rice stinks.
Then you should eat instant noodles.
I asked if you wanted to eat out and you didn't reply.
Why did you divorce dad?
You're making me lose my appetite.
Are you talking about going overseas again?
No!
Can't I even ask why you divorced?
We lost everything to his greed.
We divorced when we were steeped in debt.
I stood surety for him and only paid that back when you were in junior high.
So you divorced because of debt?
If it was just debt,
I would've earned the money.
He was an alcoholic.
You were growing day by day and he got drunk day by day.
I thought he'd die of alcohol poisoning.
I guess he hasn't died yet.
You speak so harshly.
What? What's so harsh?
Who cares? He's a stranger.
Consider yourself lucky you were too young to remember.
Look at your brother.
We just weren't a good match.
Even the fortune tellers said that we'd die if we lived together.
-Hello. -Hi.
Ryu Jihye.
-Going to class? -Yes...
Come to the staff room after this class.
Excuse me? What for?
We received word from the department of education,
and they'll offer full sponsorship to a few based on their grades.
Really?
I'll tell you the details later. Drop by the staff room.
Okay.
It's this one, right?
Department of education. English qualifying exam question book.
This is the right one.
How exciting!
So we can go together if you take this exam?
No...
I have to come in the top three in this.
Unbelievable.
Sure you can go?
It'd be easier just to pay.
It's better than being impossible.
I'll buy this for you.
To cheer you on so we can go together.
Why? Am I being a brat again?
No.
I'm just thankful.
What?
You said that.
What's wrong?
Oh, nothing.
Let's hurry before we miss our bus.
Hey, Jihan.
Isn't that your sister?
No.
Jihan, this is your sister.
Hey, it's your sister, Jihan.
What's this?
Who are you?
Jihan had a sister?
You're cute.
How old are you?*
Want me to carry your bag?
She's not my sister.
As if. She looks like your sister.
I'll carry your bag for you...
Let's go...
What's with those guys?
They're just a bunch a thugs.
I know.
-Hello? -Is this Jihye?
-It's me, dad. -Oh, yes...
Who is it?
Is something wrong?
I don't just call when there's a problem.
I just called to hear your voice.
I see...
Did you tell your mom and brother about me?
No, I've been too busy to talk to them.
I know you're busy,
but it's up to you for our family to reunite.
Okay?
Yes.
I'm at school at the moment...
Oh, right.
I'll call you later tonight.
Who was that?
Just a friend of my mom.
You must be really uncomfortable with them to have to lie like that.
I'd better get off.
Do you get off here?
Yes, for my dad's office.
He promised to have a date with me after work.
Want to come?
It's okay. You have fun.
-Okay then, I'll see you tomorrow. -Bye.
Mom, why aren't you calling the exterminators?
Hurry up and call them.
What's wrong? Another cockroach?
It was a cricket.
It was a what?
Cricket!
Crickets aren't harmful.
I don't care. I don't want to see them.
What's wrong with you?
It's not even a cockroach. Why are you making a fuss over a cricket?
They make too much noise!
Geez!
Hey, Ryu Jihan.
Long time no see!
Looks like everyone's here today.
Every time you turn up, it gets big.
You still don't have a bike?
Hey.
After going to juvie, his mom's really strict.
I'm a loser at home.
I know.
You're a total loser.
You're scared of even your little sister.
She's not my sister.
Then why do you get so worked up?
I'm pretty sure she's your sister.
What's wrong with you? Quit it with that.
Let go of me.
Hey, it's really funny.
Hey.
Are you embarrassed of us?
It's not like that.
Then what is it?
Do you get bashed at home if you say hi to your sister?
Or you think we'll mess with her?
What a man you are.
Hey, that's enough.
Hey.
You know your sister?
I wouldn't have her even if you gave her to me.
Hey!
You lost your mind?
Hey! Stop that. That's enough.
Stop that!
You'll kill him.
Stop!
Hey! Stop that!
Stop that, you fool!
Go sit down.
-Go sit down. -Are you okay?
She hit you the hardest.
I'm okay.
Of all people, how come you didn't do your homework?
I'm just a little out of it these days.
Aren't you studying too hard for that exam?
Don't overdo it.
Dad said he'd buy us dinner.
Let's go to his office together.
Today?
I don't think I can...
Let's go.
He wants to talk to you about the register issue.
Okay then.
It's really nice here.
He's taking a long time.
Thank you.
When will dad be finished?
An old client suddenly visited.
He should be finished now.
Here he is.
Thank you so much, sir.
-That guy... -Take care.
-Isn't he that thug? -Go on and say bye.
Bye.
You're here.
Jihye's here too.
Jihye, what are you doing here?
Jihye!
I'll get going then.
Oh, bye.
Ryu Jihye.
What is it this time?
Another assault?
And why are you here?
I told you Seongyeon's dad is a lawyer?
I told you so many times but you wouldn't listen.
Why did you have to come here?
Hey, Ryu Jihye.
How dare you shout at mom?
Don't play the older brother. It's despicable.
What? Are you insane?
What? Going to hit me too?
Go on then.
We're at a lawyer's office, so go ahead.
Ryu Jihye, stop that!
You're so embarrassing.
I wish you weren't my family!
Cockroaches.
A family of cockroaches.
A cockroaches family that even makes loud noises.
And I've lived in that family of cockroaches...
...thinking that I'm human.
But when my mom hit me, I realized it.
I was the cockroach in my family.
Having to remain silent all the time.
A cockroach.
Where is she?
The number you have dialed is unavailable.
Ryu Jihye, where have you been?
Why didn't you pick up your phone?
Stop right there.
You made me worry so much. How can you keep silent now?
I'll just remain silent.
I'll remain silent and out of your way.
Just leave me alone.
Hello.
Hello?
Jihye? It's me, dad.
Yes, speak?
What?
Why's my daughter being so cold?
You didn't even pick up earlier.
I was busy.
I have a really important exam tomorrow.
I see.
Did you tell mom about me?
No, mom's been busy too.
And your brother's staying out of trouble?
Yes.
Is that all you have to tell me?
I'm a little upset.
Tell me some details.
I need to know how you guys are living,
so that it'll be easier when we live together.
Are you drunk?
No, the thing is Jihye...
I'm really sick.
I need you to convince mom and your brother,
so that we can live together before I die.
I may end up dying alone...
Dad.
I'm sorry but I'm really busy right now.
I have a really important exam tomorrow.
Hello?
Jihye, don't live like that.
What?
Jihye, don't live like that.
Jihye,
don't live like that.
Not like that.
I'm hanging up.
Jihye, don't live like...
Jihye, don't live like that.
Don't live like that.
Jihye, don't live like that.
Don't live like that.
Jihye!
Aren't you going to eat this?
-I can't. It's all melted. -Give it here.
Did you do well on your exam?
I failed.
Liar.
You always act like you did bad on exams.
When did I?
I was sitting behind you for the entrance exam.
Don't you remember me asking how you did?
How can I forget that?
I met you for the first time...
...and you boasted that you did well.
You said you did really badly.
And you got a higher score than me.
I really failed this time.
There we go.
Here.
By the way.
I can't lie about things.
I say so when I like something.
I say so when I don't.
I say so when I enjoyed something.
That's why I was an outcast.
But, Jihye...
You hide too much.
You don't have to be like that.
I'm like this but you don't run away.
Do you think I'll run away?
So did you do well on your exam?
I told you I failed.
You have it.
What's going on?
Why was your phone off?
I told you I had that exam today.
I left it at home.
Why? Did something happen?
What is it?
Dad...
He passed away.
He was lying dead on the street.
He had no phone or anything.
So they contacted you guys since you're on his family register.
What about the funeral?
It's at a hospital in Changwon.
So we're heading there right now?
We don't know if we'll go yet.
We don't know what's going on there either.
What do you mean?
Since we're on his family register,
we might inherit his debt.
Let's think about this first.
Let's think about it till tomorrow and decide.
To go or not to go...
What choice did I make back then?
When I was young, it's not like I hated my dad.
But I wanted to go with mom.
Like mom said, he was always drunk.
And if he ran out of alcohol late at night,
he turned into an entirely different person.
Plus at dad's house...
-It's a cockroach... -You kill it.
There were too many cockroaches.
So many that my brother still is scared of them.
Hurry, hurry.
Hey, it's my dad.
-Hello. -Oh, it's you, Jihye.
Get in. I'll give you a ride.
No, it's okay.
Wait, Jihye...
About your family register...
I think you don't need to do it anymore.
I'm sorry for your loss. You must've been shocked.
It's okay.
Jihye.
You haven't gone to the funeral, right?
Where are you going?
Stop it.
Should I go or not?
Jihye?
At that moment, I looked at my brother.
No one asked my brother.
He just kept silent the whole time.
And in the letter...
...that my dad sent my brother,
there was nothing about him.
It was all about me and mom.
Was it because of the noisy cicadas?
My brother had no expression on his face.
But I thought he was crying out...
Don't go.
Why are you here?
Mom's waiting.
Hurry up.
Ryu Jihan.
You going home?
We have to hurry to get there in time.
I'll be back soon.
Hey!
Geez.
Have you all thought about it?
Seongyeon's dad said...
...to write a refusal of inheritance.
Dad had a lot of debt besides from the banks.
He said it'd be best if we didn't attend the funeral.
Hey, Ryu Jihye.
That refusal or whatever.
Let's write it tomorrow.
Happy?
I'm going out.
He should've stayed alive.
If he'd left after causing me so much pain...
He should at least have a good life.
Why cause me so much pain to the end?
Why?
What are you even sad about?
We've lived fine without him.
We'll continue to be fine without him.
We can live fine without him.
Dogs go woof woof.
Cicadas buzz.
All three of us cried in different ways.
My mom and brother...
...cried in their own ways.
But I couldn't hear them.
That's because I'd been blocking my ears.
Why are you being a problem right now?
You're the one who cause so much trouble!
I think my dad's final words were...
Telling me to open my ears now.
Just as the cockroaches survived...
...because they don't make a sound.
Humans cry in order to survive.
Each in their own way.
What's this? Why doesn't it finish?
Is it broken?
We bought it recently. Why would it break?
Move, move.
Mom, have you seen my passport?
What?
-Where did I put it? -You lost your passport?
-I'll check your room. -Hey, your bag.
-Bag? -You had it on the table.
Oh, dear.
Geez.
Where is it?
I found it! It's here.
I told you to pack it yesterday.
Mom, I have to leave now.
Did you call the taxi?
I'll take you. Eat first.
I'll eat at the airport.
Hey, eat the rice I made.
You made rice?
Sis, don't forget my gift.
The rice isn't even cooked.
I'll just go.
I can cook it in the microwave.
I can't trust you with anything.
At least I tried.
Hey, eat first.
It's burning.
Mom, I have to leave now.
-Eat first. -It's ready.
Eat some ham at least.
-It's hot. -It's your favorite.
-It's nice and warm. -Eat some ham.
He can't even use chopsticks.
You have to cool it more.
Just eat it.
It's hot.
You ate it all.
It's salty.
It's tasty.
-It is? -Yes.
Hey, the rice is ready.
