Mr. Kim.

I'll go outside for a moment.

Okay.

(Lee Yun A)

Well... I'm sorry.

Why are you sorry to me?

I should've come earlier.

I was late because it
felt like it was my fault.

Why is it your fault?

It was just...

his problem.

But still,

I'm a police officer.

I can't stay here for a long time.

I'll get going now.

Mr. Kim.

Your friend visited me recently.

Did Dong Jin come?

Yes.

He told me something about you.

And the rules.

He did?

What happened to me...

didn't happen because of you.

What do you mean?

I don't meet the prerequisite
conditions of that rule.

So...

please don't feel guilty anymore.

I understand what you mean.

I'll get going then.

Su Hyeon, did you hurt your leg?

Yes.

What happened?

I'm fine.

(Cheonho-ro 29-gil)

Hello.

I'm Kim Joong Hyuk.

The detective in the alleyway?

Yes.

You know Lee Dong Jin, don't you?

I'm Dong Jin's friend.

Do you know him?

Where is he?

I came to give you something.

It's something he couldn't give to you...

ten years ago.

(Report on Fatality Rates:
Denial of the Witch's Existence)

The conclusion of the report is...

that everything that happened around you...

were just a coincidence,

and those accidents...

were not caused by you.

- But... - "You're not a witch."

Dong Jin wanted to tell you this.

And he tried to prove it with data.

(Report on Fatality Rates:
Denial of the Witch's Existence)

In my case,

to say that it was a coincidence...

Yes.

You're right.

The report is full of errors.

Errors?

You applied statistics selectively.

To put it simply,

you had already concluded
that she wasn't a witch.

Then you used statistics
to fit your narrative.

Verify all the questions on that checklist.

(Korean Statistical Information Service)

(Death toll, crude death rate,
life expectancy, period of record)

(Death toll from 1997 and on,
fatality rate from 1998 and on)

(Year 2012)

(Was there a problem with the
road when the accident occurred?)

The time, Gangwon Province, Chuncheon...

Statistics on traffic deaths.

(Were the accidents concentrated
in a specific age group?)

(Abnormal weather conditions
on the day of the accident?)

(Was there a similar
accident like this before?)

In every sense,

I think you're truly a witch.

Too many people who had feelings for you...

got hurt or died.

As Dong Jin learned more about it,

he must've been more afraid...

(What's the common
factor in all of the accidents?)

and scared.

(Park Mi Jung)

Honestly, the title of "witch..."

seems more fitting for you.

"Witch?"

I heard it...

so many times.

Dong Jin has disappeared.

After leaving a message
that he was going to meet you,

he disappeared.

Ms. Park.

I want to hear about that day.

(7:48pm)

Ms. Park.

It's me. The delivery
man from Hyomyung Mart.

"The delivery man?"

Lee Dong Jin.

So it was you.

I came because I had something to tell you.

To say what I wanted,

I've worked out to get stronger...

and made many preparations.

Wait.

Don't say anything.

As...

you were directly involved,

you must've had a faint idea.

Please stop.

But...

those events weren't caused by you.

I wanted...

to tell you this in person.

It's a gift for you from
the guys in Taebaek.

And...

there's something I'd like
to risk my whole life to say.

But I won't do it today.

Mi Jung.

Do what you've always wanted to do.

It's okay to do that.

I'm serious.

In the end, because of me...

This...

is Dong Jin's room.

All this while,

he lived here.

Depending on your decision,

I can arrest Dong Jin
on charges of stalking.

If you want,

I can be a witness for you.

No way.

All of this...

was part of an experiment
to uncover the rules.

"The rules?"

It's a long story.

I'll show you...

everything he tried to do.

(Login)

"Shineonyou?"

(Password)

(Alignment of Coincidences)

It has all the information.

(I'm going to her.)

This is his blog,

which is like his laboratory.

It's based on the data he
has been collecting for years.

But...

do I have to check this?

He wished I hadn't been a witch.

If he really confirmed that I was a witch,

his experiment failed in the end.

The statistics that were
supposed to prove...

that you weren't a witch failed already...

when he wrote that report.

- Excuse me? - Dong Jin...

didn't carry out the experiment...

to prove that you aren't a witch.

What I'm saying is...

even if you're a witch,
it doesn't matter to him.

What does that even...

He just...

wanted to find a way to love you.

Now,

it's your turn to look into him.

(Hawaii Tanning)

That's so you, Dong Jin.

Your statistics are still ongoing.

You've inserted yourself
as the last variable.

(Special Investigation Team)

(Cybercrime Investigation Team)

Excuse me.

You're working hard.

Excuse me.

This is what you requested.

It won't be easy to find Dong Jin.

I know.

It won't be easy.

Dong Jin's experiment is still ongoing.

(Being in the same space
with her is dangerous.)

(If so, what's the range of that space?)

(It's approximately 10m.
It's just an estimate.)

(Student Record)

(Details of Student Record)

(Park Mi Jung's house)

(Time spent with Park Mi Jung:
5 to 50 minutes, over 10 minutes)

(Serious injury, minor injury)

(Im Ik Jong)

(Had a crush, but didn't
confess his feelings)

(Multiple injuries over
the body, food poisoning)

One.

Being in the same space
with her is dangerous.

Two.

Holding a conversation
with her is dangerous.

Being acquainted with her is dangerous.

Four.

"Confessing your feelings to her..."

Confessing your feelings to her...

- is dangerous. - "is dangerous."

- Breaking all of these rules...
- "Breaking all of these rules..."

could result in death.

"could result in death."

(Being in the same space
with her is dangerous.)

(My speculation is that
the range of distance...)

(that could cause danger is 10m.)

(The distance between my
room and her rooftop rail is 8m.)

(Considering the distance
from the rooftop rail to her room, )

(it's roughly 10m away.
This should be safe, right?)

(Being in the same space)

(Being within a 10m radius...)

Being within a 10m
radius of her is dangerous.

(Being within a 10m
radius of her is dangerous.)

(However, the precondition
for all these hypotheses is...)

(that one must have
feelings for Park Mi Jung.)

Firstly, there should be a 5kg bag of rice.

A box of cereal.

A box of cereal.

(Wallpaper and Linoleum)

A bunch of green grapes.

Ten small soy milk boxes.

Ten small soy milk boxes.

- And a box of minced garlic. - A box...

A box of minced garlic.

Wait.

Did you hurt your hand?

Did you...

hurt your hand after delivering
groceries to my house?

I hurt myself exercising.

That's a relief.

(Breaking all of these rules...)

(Breaking all of these
rules will result in death.)

I was completely clueless.

That someone...

had been shining a light
on me for a very long time.

Dong Jin substituted
himself into the last variable.

Where is he now?

You probably know the answer to that.

The answer is in the question.

(Seoul Gangdong Police Station)

Why are you here?

I'm working.

Unbelievable. How could you do this?

What do you mean?

Mi Jung is gone too.

Okay. I see.

"I see?"

That's it?

Seriously. I have a bone to pick with you.

Believe me, I'm not happy.

You've been dodging my calls
for the past week. You know?

When I came by to ask you about Mr. Lee,

you said you were busy and went
back in after you were done talking.

Come and sit down.

How many words do you speak a day?

What's the point of having a mouth?

Are you the only busy one?

I'm a busy woman too!

I see.

My gosh. "I see?" Seriously?

Is that the right thing
to say in this context?

Anyway, I never liked you from the start.

You don't know how to talk to people.

When you speak, you tend
to sound super rude and curt.

You know what? Is looking down on people...

fun for you? Does it
relax you or something?

- You really don't know? - Know what?

Where Park Mi Jung went?

I'm asking you because I don't know.

Did you wonder why Dong
Jin chose me of all people?

Mr. Kim.

Stop with the questions.
Let's have a conversation.

Why did Dong Jin record
everything on the blog?

Why did he make it possible
for me to see everything?

Well, that's because you are also...

You already know why.

I won't beat around the
bush. I'll just ask you then.

Ms. Heo.

Are you interested in me?

My gosh.

This guy... I mean...

You...

You're a straightforward guy, aren't you?

Interested in you?

What are you doing?

How many exchanges did we have just now?

What?

A lot of odd incidents
happened around me...

ever since I was a child.

(Safety Warning Notice
for Statistics Department)

(A fall from a window, a
minor collision with a car...)

I didn't know why.

But I knew I was the cause.

Isolating myself.

That was the method I chose.

Kim Joong Hyuk.

That's your name, right?

Hey. Why are you eating
alone? That's no fun.

But Dong Jin approached me.

Come on. Do you not remember me?

I didn't even answer
him when he talked to me.

But he didn't seem to mind.

Hi. My name is Lee Dong Jin.

By the way, where do you live?

I live alone near the school.

Kim Joong Hyuk! Where are you going?

Take your potatoes.

I told you I'd give you
some my mom sent over.

Enjoy.

Wait for me, Joong Hyuk.

(Report on Fatality Rates:
Denial of the Witch's Existence)

That's when I found
out for the first time that...

What are your plans for the break?

There could be more people like me.

And that Dong Jin was
trying to figure out a way.

But his effort was wasted
in vain from the start.

I can't find a way, Joong Hyuk.

That was expected.

He couldn't deny a
phenomenon that clearly existed.

Up until then, I thought
Dong Jin had given up.

- You're here. - Yes.

Do you want to drink?

There are strange laws in the world.

What if there's actually...

a law like that?

Someone is haunted by
the law of death like a curse.

If I can understand that law,
couldn't I break the curse?

Doesn't it mean I could save
the person from the curse?

Dong Jin was talking about me.

Dong Jin didn't give up.

Hey, Joong Hyuk...

No.

He never gave up even for a moment.

(Safety Warning Notice
for Statistics Department)

(A fall from stairs, Lecture Building A)

(Electrocution from an
outlet, Lecture Room 301)

Hey, Joong Hyuk. Let's go and eat.

- Okay. - What should we get today?

I hear today's meal in
the cafeteria tastes awful.

Is that so?

Why did you come?

There was something to check.

Check what?

I knew I was the cause.

But I didn't know why.

I'm done now.

And...

I do believe it.

Pardon?

That people will die
when they get close to you.

I know that better than anyone...

what it means.

As I didn't know why,

I put a very thick wall
between me and the world.

As I didn't know why,

I turned away from everyone around me.

Just like Ms. Park Mi Jung did.

But according to Dong Jin's hypotheses,

there are rules.

(I'm 10m within her
space. I must not spend...)

(I have finally come
this far. It took too long.)

(Data on Accidents and Incidents
Related to Kim Joong Hyuk)

Familiar names.

(Relations to Kim Joong Hyuk:
Friend from elementary school)

The names of people from my past...

who got into accidents around me.

While looking into the people
around Ms. Park Mi Jung,

Dong Jin also looked into people
who were in accidents from my past.

Next time, give me a heads-up.

What if I wasn't here?

This is fun, though.

Fun, my foot.

So what brings you here today?

Friends don't need a reason to hang out.

You know I didn't mean it like that.

I was in the neighbourhood
to look into something.

I'm hungry. Let's eat.

Sure.

Just "sure?"

Only using the people who were
in accidents around Ms. Park...

didn't give him a big enough sample size.

(December 21, 2022: This is heartbreaking.)

By analysing the same patterns
around me and Ms. Park...

(December 21, 2022: This is heartbreaking.)

he was trying to save me...

on top of Ms. Park.

If the rules Dong Jin
uncovered are indeed valid,

I might be able to live a
bit more harmoniously...

with other people within the rules.

Now, I get it.

I understand why he left you the clues.

You know it too, don't you?

Please answer me.

Hey, Kim Joong Hyuk!

If you are indeed interested in me,

I must protect you.

No.

I'm not.

So sit next to me.

- What are we doing... - I...

I will need...

a bit more time.

Pardon?

What time?

(The Last Variable)

(Algorithm on Minor Accidents)

(Joong Hyuk, you must love her.)

Give me...

a bit more time.

Did you just smile?

Wait. I didn't know you could smile.

Goodbye.

Thank you.

You're all checked in.

Your suitcase is in your room.

- Thank you. - Enjoy your stay.

(Mr. Full-of-Himself)

(Mr. Full-of-Himself)

Mr. Kim.

It's me, Heo Eun Shil.

Why did Mr. Lee leave far away from here?

It's rare for two people to
fall in love at the same time.

He expressed himself...

in every possible way for quite some time.

He must have thought she
would need time to open up too.

How long have you known...

that Mr. Lee left far away from here?

I found out about his
departure as soon as I started...

investigating.

Here's what you asked.

(Name: Lee Dong Jin)

Finding Dong Jin won't be easy.

(Country: Austria)

You're right. It won't be easy.

(Country: Austria,
Purpose of Travel: Vacation)

Dong Jin might've risked
everything on the last variable...

he discovered.

"The last variable?"

He hoped...

Ms. Park would love him back.

Even to them,

time is the issue.

Hallstatt.

This place produces a lot of salt.

I see.

That's why there are
many traces of salt mines.

Much like Taebaek, where we grew up.

Thanks...

for letting me know
my house was still there.

Don't thank me.

My mom...

My mom...

wanted me to let you know if we ever met...

that she felt terrible about back then.

But she doesn't have to.

Your mother...

was a very nice person.

It took such a long time...

to get here.

I'm sorry I couldn't come here...

much earlier.

No.

This is more than enough.

You came early enough.

How was the trip?

Let's see.

I was very anxious...

and worried.

Even so, I made the right choice.

You finally did what you wanted.

I did.

Congratulations.

Had it not been for you,

I wouldn't have dared to.

Thank you so much...

for pulling me out into the world.

I'm glad.

(Stop, Lap)

Ten minutes...

have passed.

Am I okay now?

We'll have to talk more.

Right.

We’ve barely spoken ten words.

I brought your phone from Korea, Dong Jin.

I love you.

Park Mi Jung.

I love you.

I love you, Park Mi Jung.

I wanted to tell you that.

But these are simply my feelings.

Your feelings,

thoughts,

decisions, and everything.
I will respect them.

Thanks.

Wait, Dong Jin.

While travelling,

I kept thinking about you.

You just...

naturally crossed my mind.

And most of them...

were worries...

about you.

I didn't want you to get...

hurt more.

Like you did, Dong Jin,

I studied the data...

about you.

Did you make...

any progress?

I figured something...

you didn't know.

I like you.

I have a crush on you.

All of those who liked me...

got into an accident...

after drifting away from me.

But when they were with me,

nothing happened.

The last variable.

Dong Jin.

Don't leave my side.

And...

I wanted to tell you this.

I love you, too.

Lee Dong Jin.

Are you busy?

What?

You must be working overtime again.

Were you here all along?

How much longer must we
meet from such a distance?

For just a little longer.

How much longer must we
only share a few words like this?

I'm sorry.

Just how much longer?

It's just that I'm anxious.

About what?

I have no way of knowing
what this feeling is,

so I have no other choice.

Is it that hard to find out?

I need more time.

Why don't you get what it is?

I've never once felt such
emotions in my life before.

That's why I don't get it.

You're an idiot. Why don't you get it?

Let me check.

Ms. Heo.

Ms. Heo?

Mr. Kim.

I...

really like you.

Ms. Heo.

Ms. Heo!

I've totally gone mad.

I have terrible taste in men.

Rules, my foot.

Idiot.

Why don't you get it?

Can't you just make a variable?

(Lee Dong Jin)

(The last variable. Don't
ever leave her side.)

"Don't ever leave her side."

(Heo Eun Shil)

(Mr. Full-of-Himself)

Hello?

Ms. Heo. Get off at the next stop.

Get off immediately no matter what happens.

What?

What are you talking about?

Don't go too far.

I'm coming. I'll come and pick you up.

- Dong Jin. - Yes?

Is the last variable really the last one?

Who knows?

Could there be another variable?

Nobody knows that, either.

Sir. Can you stop the bus?

What?

Please stop the bus. Stop it now.

What if there's another rule?

Then...

there may be another variable.

Ms. Heo.

Don't leave my side.

I won't.

Will we really be all right?

Why do you ask?

I'm terribly anxious.

Everyone is like that.

All people are anxious.

We're only...

a little different.
