Perfect Number

It stopped raining

It's a bit cold today, Yoon-Ah

What are we going to do with this?

Oh, no

Hope it's not dead

"No, it's not. Leave it, I'll take care of it later"

- See you - Ok

See you

GOOD MORNING Take-out

Good Morning Lunchbox to go, right?

Yes

It's our new dish Please try it.

Oh...

thank you Have a good day

Good morning!

One Hand Roll, please

the Good Morning Lunch guy who comes in every day

I think he likes you

You noticed it too?

You know how guys are just so attracted to me

You surely can talk

Why don't you go on a date with him?

You know I have Yoon-ah

What about her? She's in middle school

She won't oppose if you get married

I won't see anyone until Yoon-ah gets married

And I don't really like dorky guys

the nth triangular number is n(n+1)/ 2

the proof of this formula S is sigma K equals one to n

n- 2, n+1...

Who the hell cares about those stupid formulas?

Why don't you play it?

Don't just pick chords

What?

If that's a note C

If you play the twelfth fret What note is it?

It's a C, an octave higher

If you play a C and G together, what do you get?

That's a C chord

that's correct

It's also called the perfect fifth

because it's perfectly consonant

Music is

It all sounds different to our ears

But it's only a matter of how to assemble

chords in consonance

Of course, notes like C, D, and E already have existed

Like numbers 1, 2, and 3

the person who found out the relationship

between these individual notes and made formulas called chords

- Is Pythagoras - Doped-goras

this triangular number we are studying right now

Pythagoras discovered it

I'm home

Auntie...

Yoon-ah!

- What's wrong? - I feel sick

Sick where? Oh my goodness

Hold on

Yoon-ah

Excuse me!

- What's wrong? - I'm not sure

Doctor

What are the symptoms?

Her breath is irregular Fast and slow

She's having a cardiac arrest

Clear the airway and prepare CPR

- Yoon-ah! - Please step aside

Lift your head

You alright?

Ma'am this is medicine...

the man you came with left it for you

Oh

Good Morning Lunchbox to go, Right?

Yes

It's the hospital bill you paid last night

Please take it

Yes

this lunchbox is the interest

Yoon-ah likes math unlike other girls

You're a math teacher, Right?

Yes

What was that?

Nothing

- there's something - You told me to date him

thought you said you don't like dorky guys

Something must've happened

Is he free-diving?

Beginners should never try it

Yes

Fucking asshole

Son of a bitch

You laughing? Die, bitch!

Die asshole! I'm going to kill you

Asshole! Don't laugh!

Is that you, Yoon-ah? Where's your key?

Thought I couldn't find you?

Fucking bitch

You bitch

thought you could run away?

You sleep well?

Thought you can live without me?

No fucking beer?

Get up and sit down, you bitch

Girl, I went all overtown

every bar and club in Daejeon

Leave us alone please

Leave you alone? Fuck me.

Auntie, your daughter's home

Hi, Yoon-ah

You've grown up beautifully

Your daughter'? That's some fucked up family tree

Come in. Go inside

Come say hello to your uncle

You little bitch!

Don't yell at her

tomorrow, I�LL wire you every penny I have

Yoon-ah

Let me see your face

- Wow, very scary - What are you doing?

Go away

Look at her boobs

Just leave! Damn, leave her alone!

What? Let's have fun

this is nice and fresh

I'm going to kill you

Oh yeah? Let's die. Let's do that

Alright, fucking kill me

Stay still

Fuck yeah

You fucking bitch

Fucking slut

Fucking bitch

Yoon-ah

Fucking bitch! Move

Come here bitch!

"- Stop! - Come here, fucking bitch"

Let go of me

- Auntie! - Where you going, bitch?

Stop! Don't hurt her

Fuck

Is this funny?

Oh my god

Auntie

He must be dead

Who is it?

It's next door

Hold on, please

Don't come out

Yes?

Umm...

Are you alright?

What?

Yes. I'm fine

I heard some noise

A roach

there was a roach

Did you kill it?

What?

The roach

Oh, yes

I killed it

I see

Auntie

Are you going to call the police?

The police?

No

I will turn myself in

I have to turn myself in too, don't I?

What are you talking about it?

Why?

I hit him first

And I held him so he wouldn't move

Don't even think about it

No way

You were in your room

You didn't see anything Got it?

I think I can be of help

It won't be too late to call the police after you hear me first

Who is he?

It's my ex-husband

He tortured my aunt everyday

- He threatened her - Yoon-ah

Are you going to turn yourself in?

Yes

No, auntie

If you go to jail, I'm going to be all alone

No, auntie

Yoon-ah

You two did it together

No. I did it alone

She didn't see anything

She came after I killed him, seriously

the bite mark

Whose is that?

I did it all

It's impossible for you to strangle him and hold his hands at the same time

Will the police find out?

They will know better than me

No, not my Yoon-ah Oh, no

If you turn yourself in there are extenuating circumstances

But you might have to do some time

Yoon-ah might not get off clean either

You might not be able to think clearly now

but if you let me help you

I�LL protect you two no matter what

Was he supposed to come?

Did you plan to meet him here?

No, he came unexpectedly

Did he call you?

He doesn't know my number

I'm sorry

By any chance,

do you go see movies often?

Mang-won district near Han river Dead body found, calling for back-up

Hey guys

that head is like a rotten watermelon

Do you think you�ll get something?

Look here

the fingerprints are destroyed

It might take up to 2-3 weeks to identify the body

- 2-3 weeks? - Yes

What kind of lunatic did this?

The asshole grinded the body to hide the victim's identity

the killer is an acquaintance Perhaps, the closest person to the victim

So what?

We can't even ID the victim What good does that do?

What now?

Are you going to fool around until forensics come out?

The face is smashed so badly I don't think we can match a dental record

I don't know if you can ID the body

You're really good at making people feel worse

that's a real talent

Don't step around there

this is going to suck

the only thing we have is the body with two balls

the disposal of the body seems too timid to be a psychopath's job

the tires are all flat Is it abandoned?

Lift that

Is that a key?

JINSUNG Inn

Guess the bastard was in a real hurry to make a mistake like that

He didn't pay and left his stuff

I was going to call the police

Have you seen any visitors?

No idea

there are so many who come and go

the victim is 36 year old male living in Daejeon

the name is Kim Cheol-min

It's fortunate you found it

the victim was staying in a motel just before the murder, since November 7th

Luckily, we found the motel key at the scene

the DNA from the hair in the motel matched the body's DNA

Cause of death?

According to the autopsy, he was killed by strangulation

We found a consistent pattern of an electric wire

used in heating devices on the victim's neck

We analyzed it as the electric wire often used in irons

Irons?

Estimated time of death?

We estimated it as November 9th in between 4 P.M. and 1 1 P.M.

So the victim was walking alive before 4 P.M. on the 9th

- Correct? - Yes

"to be exact, he was alive till 736"

Based on what?

We found an abandoned self-service rental bicycle on the scene

Self-service bicycles?

You can easily rent the public bicycles by entering your resident registration number

It was rented from a kiosk in Sang-am district

It was rented with Kim Cheol-min's resident number

Really?

So you have a suspect?

Considering the travel path and radius,

Kim Cheol-min's ex-wife, Baek Hwa-sun is our prime suspect

the reason is?

Now, we need to find out

thank you

Kim Cheol-min was found dead

He was brutally murdered

We had some trouble locating you because your address was changed

According to the registration files, he doesn't have any relatives

Do you know of any distant relatives?

I don't think he has any

I see

When did you meet him last?

I haven't seen him since I moved to Seoul

You haven't talked to him during the recent months?

No

If you don't mind what did you do on the 9th?

Pardon?

November 9th

I worked

And after you got off?

I took my niece to a movie

Guess it was a nice outing for a change

What's wrong with your hands?

What?

Your hands...

I got hurt at work

When?

A few days ago

Hello

It's me from next door

The detectives were here this afternoon

I did as you told me

Ok. they're coming for Yoon-ah soon

Okay

What did you do to it?

How did they find out so quickly? Did they find the body?

Just answer like a machine only to the questions asked

They might be watching you from near

So even if we bump into each other, act like usual neighbors

I�LL warn Yoon-ah also

Did you tell them about the movie tickets?

No

You told me not to show them until I was asked

Where did you put the tickets?

In my wallet

No, no

the movie flyer, fold it in half and put the tickets inside

Not many people keep movie tickets

They might get suspicious if you take them out from your wallet

Okay

I will

I�LL always call you around this time

I was wondering...

Yes?

If we really should do this

You have to trust me

Alright

the only family she has is her niece

She wanted to live out her sister's dreams

She was going to raise Yoon-ah for her sister

It is so sweet of her I admire her

So she left town

Did Kim Cheol-min come here recently?

About a week ago

He went crazy here trying to get Hwa-sun's whereabouts

So did you tell him where she was?

Are you insane?

What did he do this time? Is he in trouble again?

He was murdered

Whoever did it, I am grateful

Hwa-sun will finally get some sleep at night A real good sleep

thank you

You said you saw a movie with your niece on November 9th

Do you have the tickets by any chance?

Pardon?

The movie tickets

No, I don't

Oh

I have this though

Movie tickets

For November 9th

You saw this movie?

Detective Jo, what's with you?

Why are you keep insisting Baek Hwa-sun is the killer?

She has a clear motive for murder

And her hands It's due to strained ligaments

You saw the scar on victim's neck

When you choke someone to death

with a thin wire, you will get a sprain

that's a coincidence

there's no such thing as a coincidence to a detective

Isn't it too perfect to find tickets in between a flyer from the recycling bin?

What's wrong with perfect?

When are you going to become a real detective?

From now on, it's about who cracks down first

Put out the cigarette

Let me warm up with it

No

It's cold

turn off the engine, idiot

What's wrong with you, stupid?

Baek Hwa-sun

I think the cops are watching right now

Here

Isn't that the guy who went in first?

I think so

Pizza

Movies

It's all here

How did you end up watching a movie with your aunt?

You're in middle school Don't you have a lot of friends?

Guess you're very close to your aunt

She listens well too, right? She�ll do whatever her aunt tells

Anybody can use a credit card

I didn't use her card She never gave it to me

Really?

So your aunt used it?

Yes

thanks for the drink

What is wrong?

Wait

What are you doing?

Excuse me...

You...?

Cheers

I can't believe I ran into you here this is so weird

It's good to see you

Hey, do you remember...

the woman living next door to you

that case I told you earlier

She's the prime suspect

She has an alibi but an alibi is there to be broken

It could be

Okay

Get in

Alright. See you later

Okay

Oh!

Doped out Pythagoras!

Right?

Right, right

It's been a while Doped-goras

It was good to see you

What happened?

What did you tell the detectives?

They're probably still here

Here. Act natural as if taking something from me

Get inside

She was looking out the window the whole time

As if she was waiting

Of course

the guy next door was talking to a cop who thinks you're a suspect

Must be really nervous

I ran the credit card

"She bought the tickets exactly at 7:52"

So you believe Baek saw the movie

And on Kim Cheol-min's phone record

He ordered some Chinese on the 9th and nothing else

He has never talked to Baek

Ok. think of it this way

the niece could've swiped the card

and says she didn't

Even if Baek went there herself, there is plenty of time

But there's no proof that she didn't see the movie

Don't you dare look at me like that

So this is all about that... Goldbach's conjecture

Go where?

Goldbach, stupid

Like right now, there is suspicion but no evidence

It will drive you nuts

Did you get anything from your school friend?

Seok-go

Nothing interests him except for math

Math?

Have you ever seen a genius?

It's not divisible, it's a prime number

Yo, Kim Seok-go

Doped-goras

So you're a genius?

What are you going to do with your genius brain?

Prove

Prove? Prove what?

Have you ever heard of Goldbach's conjecture?

No way

So go on

Every even integer greater than 2 is the sum of two primes

true or false?

Nobody has solved it in 300 years

What do you think?

True

then it's done Do you must prove it?

If I don't prove it, I won't know the truth

I want to know the truth

the truth

You want to find the truth

By the way, making a problem no one can solve

or solving that problem

Which is harder?

You prove that How would I know?

Here. Lilac is the taste of love, true?

Prove that, say ""ahh"""

Good

If you want to prove it, chew it well

that is love, dude Bitter, huh?

We went to high school together

It's an unexpected variable but it's going as calculated

Don't worry

But you need to be more careful about such actions

I�LL trust you completely from now on

Did the cops question Yoon-ah?

Yes. She said they were waiting outside the school

Can you get Yoon-ah on the phone?

Hold on

Hello

What did the cops ask you?

They showed me a picture and asked if I've met him recently

I told them I haven't

they asked again about going to the movies

What did you tell them?

I said I saw the movie on the 9th for sure

And I told them about my friend I ran into at the movies

Good. that's good, Yoon-ah

And one more thing

If they come again, don't be scared Just do as you're doing now

Okay, Yoon-ah?

I will

things are really happening as he said

Surveillance tapes from the theaters

Oh my head the moment finally has come

Don't be intimidated

Just watch the elevator camera

Detective Jo

Detective Jo!

Baek Hwa-sun

Did they come?

The two came they did come to the theaters

So the friend story is true

then...

I just need to find Baek leaving alone

they indeed saw the movie

Guys

What's wrong with you?

What are you doing?

Shouldn't you be asking around Kim Cheol-min's acquaintances?

Money problems, women problems Middle, high school friends

People from military service Co-workers

You

Don't go looking for motives Go find people with motives

Got that?

Got that? Answer me!

Yes, sir!

Captain

What, now what!

They want me to take the lie detector test tomorrow

I don't think I can do it anymore

I should've turned myself in that day

I think it will be better to turn myself in right now

What would happen to Yoon-ah then?

No. Just do as you've been doing

You don't have to lie

Don't worry about that

I don't know what's going on

Why is everybody asking about the 9th?

You don't need to know

the cops will soon find another suspect

You said you trusted me

that I�LL protect you no matter what

I do I trust you

tomorrow will be the last crisis

Please lift the sleeve on your left arm

I have a lot of appointments today So let's do this quickly

Don't be nervous

From now on, answer ""no""" to my questions

Are you a man?

No

Is your name Baek Hwa-sun?

No

Good. We will start now

Has Kim Cheol-min ever come to your workplace?

Have you ever met Kim Cheol-min at your workplace?

No. I have not

You said you saw a movie on November 9th Is this true?

Yes

Did you watch the movie from the beginning to end?

Yes

Did you meet your ex-husband, Kim Cheol-min on November 9th?

Meet him?

Yes. On November 9th, did you meet Kim Cheol-min?

No. I did not

You didn't see him? Not even once that day?

No

there's no need to continue with the next question

thanks for your time

- Is it over? - Yes

Wait, you skipped an important question!

Ms. Baek Hwa-sun

Did you kill Kim Cheol-min?

Did you kill him?

Who the hell are you?

No. I didn't kill him

It's a lie

What are you doing?

It says it's a lie

You're not an examiner I won't accept this

Wait, don't turn it off!

Ask her one more time

Baek Hwa-sun, Did you kill Kim Cheol-min?

We won't be seeing you anymore Get home safely

Hey, Sang-joon

Come on.

Man...

It went well as you said

Okay, you did good

Let's eat

Why doesn't he call? It would be nice if he joined us

I didn't think about that

Yoon-ah

I'm sorry

Why?

I'm really super grateful to you Every single day

Yoon-ah, promise me

You have to forget everything

You have to go on

Alright. Don't worry

Can I eat now?

Yes

Hey

You saved them, right?

What?

My flowers

I know everything

Hey

You like my aunt that's why you helped us, right?

I wanted to thank you And my aunt waited for your call

Yoon-ah

Here's your order I�LL help you with the bill

thank you

Bon appetit

What can I get you?

Sunshine Morning Lunchbox, please

Sunshine Morning?

Thank you, Bon appetit

Good Morning Lunchbox to go?

Yes

You will have to eat something else today

I heard it's going to get colder starting tomorrow

Clear Morning Lunchbox, please

Yes

I'll never forget your care, I Thank you

Mr. Kim, I�LL see you later

I see...Okay

I understand

Dude. Who killed you?

Dude!

Stop, stop, stop! She passed the polygraph

And the polygraph said she killed him

the examiner said anyone would do the same if you ask with that look

Look here, compare them to the other people

Do they look like they're enjoying an outing to the movies?

I know you don't want to accept

Are we going on a stakeout?

Welcome

Hey, Hwa-sun

I went to Daejeon the other day and heard the news from Madam Jung

Did the cops come see you?

They came a few times

I was worried that

you might be harassed for no good reason

I'm alright

If there's anything I can help

No. It's ok You've been helpful every time. thank you

It's raining

I'm alright

No. You might catch a cold

Woo-hoo! Who are you and where have you been?

Take care. I�LL call you later

No. I don't think...

I regretted letting you go like that

I won't do that anymore

Get in

Auntie, it's him calling

Hello

Was everything okay today?

Yes

Who was the man you came with?

I know him from where I used to work in Daejeon

I see

He loaned me some money before

He came to see me and I couldn't just make him leave

So we had tea

You don't have anything else to say?

Then I�LL call you tomorrow

What's wrong?

It's nothing

Hey, drenched Doped-goras!

Where have you been?

Look at all these books here

Look at these, you're hopeless

this math formula... It's sickening

You truly are doped out Pythagoras

Did you find the killer?

No. I'm totally screwed

Why?

Your next door neighbor She really screwed me up

I must be getting old

I was pretty good back in the days but now I'm a big mess

I'm looking for another suspect, but don't know where to look

Where is that fucker?

A mustache

Look at all these old notes

What is this?

Nothing. I was bored

Hey, this is Goldbach's conjecture

Are you still working on this?

Are you not going to drink?

I sure am

Are you getting some progress with this conjecture?

Right. that's why no one has proved it in several hundred years

this is difficult, conjecture...

You're right

My brain is getting dull, It's getting difficult

If I fail to prove it, I�LL ask when I get up there

What?

Up there, He will know the truth

Whether Goldbach's conjecture is true or false

In the most beautiful and simplest proof

You, a philosopher Drink up

Hey, Seok-go Are you seeing anyone?

You?

I've been married for 3 years

Also, it's been a year since I got divorced

Ugh, I really truly don't get it

You know what my wife said when she left me?

She left a famous line

Do you know what love is? She asked me that

She implied that I never truly loved her

But shit. think about it What is true?

What is real? What the fuck is real love? Shit

You said love is bitter

What?

You said Love is bitter

When did I say that?

Li...Lilac! Right?

You remembered that? You're a mathematician

Doped-goras is smart

I am so jealous of you, Kim Seok-go

You are awesome doing all this math

this is what's real, Mathematics

What the heck is the Perfect Number?

I'll never forget your care, Thank you

Are you up?

Yeah Hey, last night...

Why did I drink so much last night?

I didn't do anything weird, did I?

I feel really shitty

Good luck on your test Are you coming straight home after school?

- Yeah, see you later - See you

GOOD MORNING Take-out

You still go to this place?

Didn't I tell you?

I always buy my lunch there

Don't you feel awkward? Eating lunch prepared by a murder suspect?

Though you wouldn't care about something like that

I'm going to wash up

I think I'm sobering up It's getting cold.

Go under? Okay under

Aren't they cold? It's not summer anymore

these people here are always the same like clockwork

So I've heard they are precise like a clock

We're always fast or slow living life in a hurry

If we free ourselves from clocks, will we be more punctual?

Who is he staring at?

Bye

Hey

Aren't you going to pick up lunch? You have to eat

Hello

No, no, no. I'm not a cop today I came as a customer

Okay

Let's see. What should I get?

What are you getting?

He always orders Good Morning Lunchbox

Okay then, two Good Morning Lunchboxes, please

Okay

Hey.

Did you find out? Hold on

Sorry but do you have a piece of paper?

Okay. So what?

Hold on

Sorry. the pen isn't working

Choi Chan-min?

010-3413...

728...7287

87 Correct? 87? Okay, be right over

thank you

Welcome

Hello Mr. Nam, you came again

Here you go

How much is it?

- It's 12 dollars - 12 dollars?

I stopped by on my way to work

I wanted to try the lunchbox you make

You're busy from early in the morning

What should I get?

Aren't you leaving?

Oh yeah. I am

Do you go ice climbing?

I heard that is great

Heard the snaps on this thing is terrific

I don't do ice climbing but the customers have complimented on it

Excuse me, please look around

I...

I don't think we should see each other anymore

I came here to tell you that

I'm not saying we need to do anything right now

We have our own situations, so let's take it slow

Did you forget everything I've done for you?

Watch me

Watch what I will do

You're late

It's okay. No one's watching us

You were charged more this month for the water

What?

I hear some leaking sound at night I was wondering if you knew

You want me to fix it?

No, it's fine

Alright then

See you later

By the way

Your clothes seem gaudy today And your make-up is heavy

Detective Jo!

What are you doing out in the cold?

- I brought some hot... - Left the bicycle

Left the bicycle with flat tires here

Bicycles?

Meticulously destroyed the victim's face and fingerprints

but left the victim's things on the scene

You're saying the killer left the bicycle on purpose?

What if he did?

And tell us the time of the murder?

Why would he do that?

To prove Baek's alibi

What?

In order to prove Baek was in the theaters

when Kim Cheol-min arrived here

that's why the tires are flat

So no one can ride it

then the window of time for murder is spread

out and Baek's alibi becomes insufficient

You still think Baek killed him?

What if

"Baek was at home in between 6 and 630"

And Kim Cheol-min was killed there

No way

How can she move the body from her house to here in 30 minutes?

She even has no car Did she grab a taxi?

Also, she had to rent the bicycle She can't do all that by herself

It's impossible, right?

No way Especially, a woman by herself can't

the victim's clothes we found here What was the size?

What about it?

That's not important. I found another suspect

What?

Did Ms. Baek ask you to kill Kim Cheol-min?

Hwa-sun could never kill someone or hire a hit man

And do you think I'm stupid?

Even if I like the girl you think I'd kill someone?

Then you killed Kim Cheol-min without her knowing?

Because in order to be with her, Kim Cheol-min had to disappear

What?

What did you do on November 9th?

Look here guys

When will you stop bothering Hwa-sun?

Well...

Until we have no reason to

November 9th

He's not our guy

Geez man

He has a clear motive A motive!

So the motive

the reason

What?

There is someone but...

Yeah? Who?

But there is no motive

Write question #1 on the board and if you have the time, do it up to #4

Hey

So you are the disciple of Doped-Goras

Excuse me?

Back in school, your teacher's nickname was Doped out Pythagoras

Aren't his problems difficult?

Everybody says it's hard but I like it

Oh yeah? Why?

Well..

His problems have blind spots that mislead people

It might seem like a geometry problem But it's actually a function

You're killing them all

Go on

Yes, sir

Study hard

Let's go to the break room

Okay

What's up? Obviously, you're not here to check out my tests

Don't take this personally

According to this, you skipped the morning class on November 10th

And you came to work in the afternoon What happened to you?

A cold

Really?

What do you mean?

And you were absent on the 9th

I heard that you sometimes skip morning classes to do your math research

But the administrator was surprised that you were absent on the 9th and 10th

Said you never took off for two days in a row

I haven't?

Is that weird?

A scrupulous person like you

It's odd you didn't come to work for a mere cold

On top of that, you were absent the day before

Did you go see a doctor?

What do you want from me?

I suddenly want to ask you this

Making a problem no one can solve

or solving that problem

Which is harder?

Did you pity Baek Hwa-sun?

She killed a person

I have to go

See you later

Auntie

the next door, He is here

What're you doing at my place?

You're home

I'm almost done

Isn't Kim Cheol-min about tft 6in?

Don't they seem too big?

These fit you

Don't they seem too big for tft 6in guy?

Guess so But you can wear pants however you want

I felt uneasy so I thought well and hard

But this has to be an unmotivated murder

that's why there's no suspect

You think a psychopath did it?

Usually, when a murder happens the killer will do anything to hide the body

Bury in the mountains or sink it in a reservoir

Even if he didn't have a car

Han-river was right in front of you

If I were him, I�LL tie the body with something heavy and sink it under water

So you're saying

the killer left the body on purpose for others to find

Yeah, he's a psychopath He wants the world to know what he did

At least that's my guess

then think about it this way

the killer wanted the body to be found

that's right

then this actually makes sense

Nov. 9th Absent Nov. 10th Absent

His problems have blind spots that mislead people

It might seem like a geometry problem But it's actually a function

Right?

JINSUNG Inn

there was an empty noodle bowl and he was gone

So you didn't see him the day before his murder either?

Chinese food...

think it was around midnight He asked about food delivery

I gave him the number for a chicken delivery

Over the phone?

So you've never really seen the guy's face. Have you?

Mister

Mister

No, no wait!

Mister!

Wait

Mister!

Hey!

You going up?

Stop right there! Hey!

Until now

I only focused on Baek's alibi

But the alibi wasn't important in this case

the problem was the dead body

Really?

But I...

I hope I'm wrong

Looking at the homeless, you said they are precise like clockwork

And you said when one gets free from clocks, one will become even more precise

that's for people who are aware of time!

For people living within the clock!

I have no idea what you're talking about

Did you kill someone?

Even if you solve this problem, it won't make anyone happy

Nor change anything

You...

You think it's going to change anything?

Yoon-ah must be really gifted at math

What brings you here?

It's just that...

I received these at the store today

Stay away from Baek Hwa-sun

You bastard can never make her happy

Is there anyone you know who might do this?

Should I call the police?

No, no police

You said you trusted me

that I�LL protect you no matter what

Please let me in

I have to ask you something

Seok-go

You like me, don't you?

That's why you're helping me Isn't it?

The past few days, you feel like a stranger to me

You sent those pictures, didn't you?

What?

You don't want me?

Isn't this what you want?

I should've known

there's nothing free in this world

All men are the same It's so obvious

Do whatever you want, do it

Who cares if you're a pervert

I brought this unto myself

Why?

Why are you doing this to me?

I barely escaped from a lunatic

How can I live feeling so suffocated?

What is it you want from me?

Go home

Yoon-ah's waiting

Do you love Baek Hwa-sun?

Who? Who are you?

How much do you love her?

Can you die for her? Huh?

What the...

Who the hell are you?

What the fuck? Asshole

Who the hell are you? Come here fucking

- Asshole! - You want to die?

Who the hell are you?

You're that fucker You sent those pictures, didn't you?

You messed with the wrong person You crazy asshole

Did you find it?

He could be a real criminal Look closely

Not over there, look up! If you don't break up with him I'm going to kill him myself

I got it

I saw him for the first time on November 9th

Kim Cheol-min... that filthy piece of trash

He was lurking in front of the apartment

As soon as I saw him, I knew he was Hwa-sun's ex-husband

How did you know right away?

I know everything about Hwa-sun

What kind of music she listens to

What kind of things she likes to talk about

Which TV series make her cry

Since when?

What the hell happened?

Your friend is a total psychopath

Just now, he was caught in the act, trying to kill Nam tae-woo

He also confessed to the murder of Kim Cheol-min

What?

And we talk through the walls

the walls?

I can hear everything Hwa-sun says

She knows that too So she talks to me through the wall

She said to kill Kim Cheol-min

She said she's miserable because of him

So I did what she asked

But how could she date another man?

Bitch

I should've killed her first

I found this in your mailbox

You received threatening calls at the same time every day. Didn't you?

We searched the call history from a payphone booth

the guy next door, he is a total psycho

He just confessed to the murder of Kim Cheol-min

Stop there! Captain's going to be back soon

- Just give me ten minutes! - Detective Jo!

Wake up, bastard

Get up and look at me

Seok-go Stop with the acting

You didn't kill Kim Cheol-min

At first I thought...

You took pity on Baek and she asked for help

So you unwillingly helped her move the body

But the Kim Seok-go I know He won't kill anyone for no reason

Because he is rational and logical

But I overlooked something

that as long as the logic fits, you can be the most brutal person

that day, I saw the way

you looked at Baek

Oh, this bastard is in love

then, when Kim Seok-go falls in love,

what would he do?

When his loved one is in danger

He will plan something. Right?

A flawless and perfect plan!

That's interesting but...

A hypothesis needs a proof in order to become true

Fucker! Are you going to ruin your life for that woman?

I just confessed to the murder of Kim Cheol-min

Even if you solve everything,

my trial would've been over by then

If I get convicted in the first ruling and I don't appeal,

then Kim Cheol-min case is over

No, no. this is wrong You're out of your mind

this is not love this is not real

How can you waste your genius brain?

It's not about my brain

It's my heart

Bastard...

Bastard You shouldn't have let me catch you

Bastard

Let me ask just one favor

Ms. Baek

I don't know where to begin

I don't know what's happening right now

But I came here to confess the things I've been hiding

Seok-go wanted me to give this to you

I don't know what's in the letter

But it's probably not what I'm about to tell you

It makes sense you don't know anything

Because you've been doing what Seok-go's been telling you

It's only natural that you passed the polygraph

You never lied

On Nov. 9th, you actually did dine out and see a movie with your niece

But you probably wondered why people only kept asking about Nov. 9th

because you killed Kim Cheol-min, on the 8th of November

Yes, Seok-go isn't innocent He's guilty of a crime

Mang-won district riverside murder

Kim Seok-go is the killer

He really did kill someone

that day,

the first day of murder on November 8th

Seok-go probably contemplated over the dead body

If the police finds the body, they will find the real killer

Even if the body is never found

he thought you would live your life in agony,

worrying when the body will turn up

So Seok-go decided

to commit another murder

His plan was to trick us into believing the body was Kim Cheol-min's

Just in case, no matter what happens he couldn't back out

He perfectly blocked off his own exit to make it impossible to undo

Hello

Inn

Seok-go made someone you don't know into Kim Cheol-min

And kills him in the same way

So the body we found wasn't the real Kim Cheol-min

And then some place where no one knows

Seok-go probably hid Kim's body

so that it can never be found

But you see

the person Seok-go wanted to deceive perfectly

was you, Ms. Baek

that's why Seok-go stalked you

But then, an unexpected variable me, popped up

Protecting someone until the end

Even taking the blame for someone else's murder

Is this possible for a normal person? I'm not sure

Are you his family? Are you his wife?

You're not even his girlfriend

From the beginning,

he planned to take the blames for you

So now

Everything is up to you

I just don't want that stupid bastard...

to be miserable

this is my heartfelt honesty

And it is the truth

I want to thank you for everything

Because of you, I was able to keep going with my life

I don't know

I don't know!

Auntie, what are you doing?

Huh? Hand me that

Wow, you put everything in order

May I bring in the ones outside?

No

Until you showed up in my life

I only thought about dying

I believed math was the only perfect thing in life

So when I couldn't find the answers anymore,

the joy became agony and despair

Maybe it was the loneliness

- Hi - Hi

We just moved in next door

Here

My aunt made it I can't guarantee the taste

Is there maybe something I can help?

Pardon?

It's nothing, bye

That guy is a bit...

But you can't guarantee the taste?

I'm joking

You know what's in those rice balls?

That's when I realized

There's something essentially as beautiful

as the beauty of math in this world

Hello

Hello

Miss

those rice balls were good

that's great

If you want, you can eat it every day

You really came

Hello, sir!

I'm late

Hwa-sun and Yoon-ah

Thank you so much

Mr. Nam seems sincere and trustworthy

I hope he makes you happy

Please forget everything about me

and what had happened Don't ever feel sorry for me

If you are not happy,

all my effort becomes meaningless

If you ever turn yourself in because of guilty conscience

There's no longer a reason for me to live

This is my last request

I'll always pray for your happiness

Always, Kim Seok-go

Seok-go

Wait

Seok-go, wait Just need a word

- What is it? - Please Seok-go

- Stop the bus - Isn't that Baek Hwa-sun?

Can you see me?

Can you hear me?

I'm sorry, Seok-go

Sorry I said I feel suffocated

I shouldn't have said that

Seok-go, I...

Seok-go! Why did you do all this for me?

You can't just go away like this

Seok-go

- Let's get going - Seok-go

Seok-go, Seok-go!

Ms. Baek!

- Seok-go! - Ms. Baek!

What will happen to him?

This is all because of me

You're the sole reason I'm still here

I'm so sorry
