(Abstract)

(Natural Disaster Occurrence Status)

You used statistics to prove that...

a series of accidents and deaths
in a village had nothing to do...

with one individual. I liked that idea.

But...

it's useless now.

It's too late.

No.

Your report was useless from the start.

It was full of 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.

This isn't mathematics.

Take it.

Why are you giving this back to me?

Verify all the questions on the checklist.

Then it will be clearer
if she's a witch or not.

Go back to the beginning. What do you say?

Okay.

Teenager accidents...

life expectancy, period of record)

(Save charts)

The death and accident
rates at Midong High School...

were significantly higher than
those of schools in other districts.

Statistics on traffic deaths.

If the accident rate is higher than
the average in the other regions,

there must be a reason.

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

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

The time. Gangwon Province...

(Was there a cause that influenced
the increased accident rate?)

The accidents had to be connected...

- or share a common cause. - Rainfall...

Rainfall...

The accidents were neither connected...

nor shared a common cause.

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

"What's the common
factor in all of the accidents?"

The only common factor in
these accidents and incidents...

(Park Mi Jung)

It was only Park Mi Jung.

(Park Mi Jung)

Is Park Mi Jung...

really a witch?

Although I wanted to prove
that she was not a witch,

my error-filled report...

pointed to her as a witch.

I'll start the battle of my own from here.

(Episode 4: Error of Statistics)

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

Thank you for your hard work.

Not at all.

How was it?

Even if you correct the
misapplication of statistics,

the target value was set
incorrectly from the beginning.

It means...

even though you wanted to
prove that she wasn't a witch,

but you pointed to her as a witch.

That's true.

Because the only common
factor in the incidents was her.

Okay.

This is a crime map created by the
San Francisco Police Department.

They created a crime map...

that indicated the location, time,

and severity of crimes.

The police department thought
the date they had was insufficient.

So they analysed the data
that included hidden crimes,

which they discovered through
direct interviews with local residents.

Based on the crime map they created,

they reassigned patrol areas and personnel,

and the results were astonishing.

The crime rate in San
Francisco decreased significantly.

So are you saying...

you're going to make an
incident map related to the witch?

Bingo.

The goal is to extract the pattern
of incidents and accidents...

that occurred around the witch.

If we can identify the variable
that affects this pattern,

we can predict potential future incidents.

If we can predict it, we can
also stop it from happening.

But we don't have enough
data to find the pattern, do we?

We should still try, though.

It might save...

someone.

Such a beautiful monastery...

- This castle is also known as...

the background of the
Grimm Brothers' fairy tale,

"Rapunzel."

It's also known as the
background of the fairy tale...

written by the Grimm Brothers', "Rapunzel."

Rapunzel was trapped
alone in a high castle...

because of the witches.

Because of the witch's curse...

Hello?

Si Ri.

I uploaded the translated
transcript of the French edition online.

Okay. Good job.

Thank you for always keeping the deadline.

I can make a living thanks to you.

I should thank you.

Have you eaten?

Have you not eaten yet to save money?

No. I'm on a diet.

You have no fat to lose.

Do you think I don't know you?

Where will you use the
money you save like that?

I...

want to go somewhere.

You do?

Hey, that's good news after a long time.

You better eat something quickly.

Okay. I got it.

Mi Jung.

If you get sick while trying to save money,

you'll have to spend more
on the hospital and medicine.

Gosh, stop nagging.

I'm hanging up. Bye.

This is my own world.

People exist in the
world, and I exist here.

I locked myself in here.

I don't meet anyone.

Sometimes, I'm confused...

if I confined the world...

or the world confined me.

But I'm okay.

Are you okay?

Are we really okay?

(Current Affairs and Cultural Programs 1)

Zero plus...

And...

It's the square of negative one.

(Ratings of Programs)

Square root of four...

plus 1. And 1 minus...

(Common Subjects, Mock
Test Based on Past CSAT)

two plus three.

So the limit...

as "t" approaches infinity.

It approaches infinity.

Let me see. This is...

Two plus four equals...

(Vision Trip)

What are you doing, Ms. Heo?

What is this?

You should answer the question.

You can't toss the question to me.

"Vision Trip."

Did you reject the proposal?

Oh, this?

Just keep doing the same
thing. Let's not stand out.

It's not cool to repeat the same thing.

I need something new to get excited about.

If a nail sticks out,

what else is there to do
but hit it with a hammer?

Don't you know that straight
trees are the first to be cut down?

Just let Team Two handle...

the experimental and new stuff.

Instead of nurturing your juniors,
you're blocking their path forward.

Hey.

Am I your parent?

Who nurtures who in this harsh world?

Everyone should find
their own way to survive.

I...

need to stay here for a very long time.

My children still have a long way to go.

I'll be stuck on the ground
like a fallen leaf soaked in rain.

No matter how much they try, I
won't let them sweep me away.

You don't have any ambition.

Your juniors will learn nothing from you.

Gosh.

Ambition?

I don't need it.

Look at this.

Look.

(Mathematics)

I don't have the money to pay for a tutor,

so I teach math to my
daughter who is a senior.

My already thin hairline has fallen out.

Do you know why I'm doing this?

Because I'm a father.

Because I'm a father, I'm
doing pathetic things like this.

(Vision Trip)

Whatever. Don't look
for me starting from today.

Hey, Ms. Heo.

Heo Eun Shil!

That crazy punk.

It's so sudden.

I'm sorry.

Don't do something to be sorry about.

What are you doing, Mr. Lee?

Dong Jin.

We have so many things to do.

What can I do without you?

Think about Shine Solution.

We have more than 30 employees now.

There are more than 100
people, including their families.

I'll make sure to finish the
digital logistics system project...

we're undertaking...

with the Ministry of Land,
Infrastructure, and Transport.

Dong Jin.

Dong Jin. Don't you know that
casino investment contracts...

are being exchanged?

You can handle it.

I'm not even in charge of it.

The chairman keeps telling
me that he wants to eat with you.

What do I do?

I'll contact him privately.

Jung h*.

Do you remember the consulting
project with Seohan Bank?

It was about the small
business loan algorithm.

Seohan Bank?

Data might not be everything.

What if data isn't everything?

Things other than data only
hinder the accuracy of the algorithm.

That's what you said.

Right.

Dong Jin.

I don't know what made
you feel skeptical about this,

but if you quit like this, other
people will take the credit...

for what we worked so hard for.

Is it because your stake is too small?

I was clueless.

Fine. I'll give you an additional
three percent of the shares.

Okay. Let's do this then.

I'll increase your stake by five percent,

and give you a ten percent incentive...

- for each project. - Jung h*.

You know that's not what it's about.

Just think that it's a sabbatical year.

A sabbatical year?

You're too young to have a
sabbatical year. Team Leader Lee.

No. Director Lee.

Can't you grasp the situation?

The atmosphere has been good.

You should work harder
when the time has come.

Are you burnt out?

Jung h*.

There's something I must do.

I think I'm going to regret
it if I miss this opportunity.

Okay.

Don't go too far.

The water pressure is nice,

and the hot water works well too.

Your neighbours mostly
live alone, so it'll be quiet.

When are you going to move in?

As soon as possible.

If it's urgent, you can move in right now.

Still, you better check other things too.

Try flushing the toilet.

But I want to move into
the unit upstairs, not here.

It's already taken by someone.

Can I still have a look?

How can we see the place
when it's not even for rent?

It has the same layout
and size as this place.

There's no difference.

It has to be the apartment upstairs.

Can you please let me see it?

Well...

I can ask if you can take a look.

But this person isn't home.

Why should I?

Let us just take a look.

It won't take long.

So why should I do that?

Please let me take a look.

He must have a reason.

Could you please let him take a look?

Come on. I covered for you
when you were playing the guitar...

and people filed noise complaints.

No.

My gosh.

My goodness. Come on.

Gosh, that tenant has quite the temper.

On top of that, he never pays rent on time.

I often avoid him because
he can get a bit scary.

So don't take it personally.

I won't.

My goodness.

Wait! Hold the elevator.

Thank you.

Hello.

Hey.

Do you like rice cakes?

What? Rice cakes?

Like rainbow rice cakes
or sirutteok. Any favourites?

My parents run a rice cake shop.

I hate rice cakes.

My gosh. I see.

That didn't cross my mind.

Okay.

Could you recommend a
nice boxed meal for me?

The spicy pork with kimchi and
tuna bibimbap are most popular.

(Spicy pork with kimchi)

What's a popular drink then?

What's...

The carbonated water and energy drinks.

(Boxed Meal)

It's 11.3 dollars.

Do you want a plastic bag?

You don't need one, right?

What?

Enjoy.

What?

- Sung Min, let me do it.
- What are you doing?

- I'll do it.
- I'm great at this. I can do it.

- I'll do it for you. - What are you doing?

I'll do it.

You shouldn't do this.

I can take care of this. Okay?

Why would you do this? My goodness.

Fine, you do it then.

Sung Min. See you around!

(I'm new to the building. I
hope we can get along well.)

Come on.

Who is it?

Mister.

Why are you doing this to me?

Happy now?

Would...

three months' rent and
moving expenses be enough?

Oh, well...

You don't have to do that.

I emailed you the materials
for next week's meeting.

Right.

I also uploaded the data analysis file...

regarding the Ministry of Trade,
Industry and Energy project.

Okay, I got it.

Dong Jin. Everything
is okay with you, right?

Yes.

Jung h*.

I'm sorry for causing you concern.

- Bye. - Bye.

Bye, kids.

(Gangdong-gu, Seoul)

(Hyeom Publishing House)

Oh, right.

May I help you?

- Sorry? - Who are you looking for?

Sorry?

Oh, right. I'm just headed...

to the third floor.

I see. The third floor.

- Yes. - Okay.

(Brazilian Waxing, Bikini Waxing,
30 percent off for off-season)

(Full face waxing: 72 dollars,
armpit waxing: 12 dollars)

Welcome.

This looks good.

I'll put a piece of kimchi on it.

It's so good. It's amazing.

Is this for real?

Here. This is for you.

I'm good. I feel full just
by watching you eat.

You always sound like my mom. My goodness.

This is so good.

Eat a lot then.

I want to save up money and go on a trip.

Yes. You translate
travel shows for a living.

But you never get to travel.

Please go and travel.

I came across this place while translating.

It's not an island, but it looks like one.

And it's not so crowded.

Nice. Where is this place?

Hallstatt in Austria.

Is it because not a
lot of people live there?

I just thought...

things might be better abroad.

Yes. Let's work hard then.

My gosh. You did a great
job with your vegetable garden.

Cherry tomatoes, lettuce,
perilla leaves, and napa cabbages.

I try to grow my ingredients
in my garden if I can.

That's amazing.

Oh, my.

Hey, you're a city farmer.

My father was a farmer.

I'll plant potatoes next spring.

Can you also grow
potatoes in this small place?

Of course.

Potatoes grow anywhere
as long as there's enough soil.

Why didn't you plant them this year?

I saved a task for next year.

You saved a task?

Yes. That way, I have
something to look forward to in life.

But why potatoes of all crops?

Well,

potatoes hide underground,

but they grow well on their own.

And it was also the last
thing my father planted.

Will you keep bringing up sad stories?

This isn't a sad story.

It's a happy story.

I'm happy to see that you've
become more cheerful lately.

You're smiling more too.

Of course. I must live diligently.

Yes. Let's live diligently.

Let's go to Hallstatt.

Thank you for helping me...

get the translation jobs
with the publishing house...

as well as the travel documentary.

My gosh, stop it.

This is Lee Dong Jin speaking.

This is Detective Cha Kyung
Soo from Gangnam Police Station.

I'm calling you because
we identified a suspect.

His name is Lee Joong h*.

He's on the wanted list.

So arresting him will
only be a matter of time.

We looked into your case.

He ran a company named Seonil Products.

He used to run a small
factory that made paper cups.

But his company went bankrupt.

His loan was approved by the bank.

But a change in the bank policy...

wouldn't allow him to get
the loan, so he went bankrupt.

This guy went to the bank...

and made a huge scene.

The employee at the bank
mentioned your company...

because your company created
the system for bank loans.

My guess is that...

he saw you on the company's website...

and targeted you.

That's how it happened.

A grudge...

What...

would happen if I were to drop the charges?

Will you remove him from the wanted list?

It's a serious crime.

It could help reduce the sentence.

But he will have to face
criminal punishment.

It's not like he turned himself in.

He's on the run.

- I see. Okay. - Okay.

Bye.

I have one more question to ask.

Where can I file a report
regarding flickering streetlamps?

Streetlamps?

Streetlamps...

- Detective Jang. - Yes.

Which department can he talk to...

about flickering streetlamps?

He can contact the Facilities Department...

at the borough office.

You can contact the borough office.

Okay. Thank you.

Mr. Lee Dong Jin.

What's your problem?

You're him, right? The
guy from Shine or whatever.

Are you Lee Joong h*?

You jerk.

You jerk.

Hey.

To you, people are mere
numbers. Aren't they?

- Hey! - You jerk.

- What are you doing? - Get off me.

- Are you all right? - You jerk!

- Hey! - I got him. Call the cops now.

- Let him go. Get back to work.
- Get off me.

Get off me.

It's fine. Don't call the police!

You jerk.

Why me?

Why did it have to be me, you jerk?

The loan was approved.

I was going to pay back
the promissory note...

and settle all the overdue wages.

Everything would have been sorted out.

But my application was
denied at the last minute.

Do you know what that means?

All of us...

Dozens of people lost their jobs overnight.

You jerk.

Darn it.

Darn it.

Actually,

this was the first time I've
been beaten up like this.

And it was also...

the first time hearing a
stomach growl while getting hit.

Have some more.

Apparently,

their spicy pork with kimchi and
tuna bibimbap are pretty good.

Especially, the spicy pork with kimchi.

It is number one in the industry.

The main customer group for boxed meals...

from convenience stores consists
of men in their teens to 30s.

Everyone in the food business knows...

that men love spicy
pork thanks to big data.

But the competition became too intense.

It was hard to win over
customers with just flavours.

So this convenience store brand...

added a fried egg.

Like how restaurant owners would serve...

fried eggs for free to their regulars.

That's what I do.

I add fried eggs to the meals.

But...

I didn't do that as a
generous restaurant owner.

Well, adding a fried egg...

would incur 30 cents more
to make the boxed meal.

But the sales would go up by ten percent.

I would put together how much
it'd cost to set it up and so on.

I would gather a lot of data...

and calculate numbers to the best I could.

I would give it my all. I
would do my best for it.

Oh, right. I do my best for everything.

I worked so hard to the point that...

my college professor...

told me to stop working so hard.

I'm sorry.

My family is all broken up.

My son...

went to his uncle's house in Masan.

My daughter, the apple of my eye,

went to Cheongju to
live with her great aunt...

whom she had never met before.

My wife is staying in a dry sauna.

I sleep in the Internet cafe.

I didn't want to let my family down,

so I worked hard.

But...

I lost everything in an instant.

Everything was gone just like that.

I didn't have the courage
to start over given my age.

"Fine."

"Let's end it."

"It will be over with me gone."

I was staring down at the
Han River for a long time.

I suddenly felt it wasn't fair.

(Seohan Bank)

I decided to find the guy...

("Lee Dong Jin Develops
Loan System for Seohan Bank")

who was responsible...

and take him down with me.

But...

you saved me.

I'm so sorry.

I know this isn't enough to console you.

But I didn't know any better.

I didn't do it with malicious intent.

I'm truly sorry.

Can you take a picture of this too?

You said nothing was missing, right?

It appears that way.

There's no sign of forced entry.

So the culprit must know the passcode.

Does anyone come to mind?

Did you recently go
through a breakup or a fight?

Well,

it's nothing like that.

Hyun Woo.

Do you have a place to
stay for the time being?

Yes.

You should request protection.

Then you can get
protection from the police.

Install a CCTV or wear a smartwatch.

Will you come at any time?

Press a button when you're in danger,

and a district or appointed
officer will rush to you.

Can I...

appoint the officer?

Yes.

Thank you.

Yun A.

Are you okay?

- Goodness. - Mom...

It's okay.

You're okay.

(Gangdong Police Station)

To arrest the culprit
on their first offence,

I think we should do a stakeout first.

Hi, Dong Jin.

Hi.

Have you been well?

Yes, I'm always the same.

You must've shot an action movie recently.

An action movie?

I sure have. But I wasn't
the main character.

I was an extra done after getting beat up.

That's very unlike you.

What brought you here without a call?

I was around the area and thought
we could catch dinner together.

"Dinner?"

I'll excuse myself first.

I have a date with my girlfriend.

Bye, Joong Hyuk.

Let's go.

Okay.

Your face. What really happened?

I deserved to be hit.

I don't believe you. You
wouldn't bully anyone.

I have a side you don't know.

I'm sorry.

All of a sudden?

This and the last
incident. I was of no help.

I'm not a kid.

Joong Hyuk. I can take
care of my own business.

It seems like things keep
happening around you.

Is everything okay?

What should we eat?

Today...

(Protection Request)

(Protector 1)

Let's have dinner next time, Dong Jin.

Hey, Joong Hyuk!

What's going on? Joong Hyuk!

I'm the protection officer
from Gangdong Police Station.

What happened?

What took you so long?

We're screwed.

There will be even
more talk about it. Darn it.

What...

Did something happen to Lee Yun A?

- How is she? - She bled too much.

(911 Paramedic)

Yun A...

Weren't you the appointed
officer? Why are you here only now?

What was the use of asking for protection?

We needed you to stop such incidents!

Honey. Stop it.

Come on, honey.

Let's go to Yun A. Hurry.

My apologies.

Honey.

Let's go to Yun A. Please.

Come on.

Our dear Yun A...

Yun A...

(Kalguksu)

Oh, welcome.

Come over here.

It's good you didn't get lost.

Take a seat.

Setting up a time to meet you was tough.

But to think you'd contact me first.

It's an honour.

My apologies. I had a lot to take care of.

Yes, I can tell from your face.

You don't seem the
type to fight with others.

What happened?

Well, you see...

I fell down and got hurt.

You're bad at lying.

The kalguksu here is right up my alley.

Sweetness is the key to red bean kalguksu.

Here. Dig in.

Yes, sir.

Make sure to add a lot.

(Kalguksu)

The cold wind makes me...

crave this place's red bean kalguksu.

This has been my lunch for the whole week.

I'm happy about it, but not them.

You may leave first if you're done.

Aren't you all busy?

Yes. Please excuse us first, Chairman.

Go ahead.

I wondered why this craving wouldn't stop.

I must be...

missing my mother greatly.

The red bean kalguksu here...

tastes just like the one my mother made.

I guess I miss my mother
a lot despite my age.

All right. So you had a favour to ask?

Oh, yes.

Let's see.

(Resume)

Who is this man?

I learned what you meant...

when you said not everything in life...

could be answered with numbers.

He unintentionally suffered because of me.

Things like that can happen while working.

When...

that happens, will you go around
making amends every time?

I'd appreciate it if you could
give him a small duty in the casino.

Right. If he's someone you guarantee,

I shall hire him for a suitable job.

Thank you, Chairman.

In this day and age,

people are only
interested in their business.

Nobody cares about others. Don't you agree?

But you're trying to rescue someone.

You intrigue my interest.

- Drink. - Yes, sir.

(Alarm)

The time when the
streets are the most empty.

That's when I step outside.

(Brazilian Waxing, Bikini Waxing)

(Math Academy)

Wait.

The light's been fixed.

Here.

You were hungry, weren't you?

Avoiding people was tough, wasn't it?

But...

seeing you come to me when I come around...

makes me feel like I'm a real witch.

Like a fairy tale heroine
cursed and trapped in a castle,

she lost her own life.

I will somehow find a way.

No matter what it takes,

I will break the curse she has...

and restore the life she lost.

(Taebaek, Jeongseon)

I'm going back to the very beginning.

In Taebaek, where we
were both born and raised,

I will find a clue to lift her curse.

Hey.

Give me a minute.

You came earlier than expected.

It's a weekday, so there was no traffic.

Do you want some tea?

No, I'm good.

I have another place to be.

Hey. How long has it been?

Let's see.

Three years after my mom passed away.

You're so indifferent.

- I'm sorry. - No. I'm the same.

But will everyone be free?

Min Jae and h* Young
will be happy to see you.

Remember Da Eun?

Yes, I do. Da Eun from liberal arts.

Yes. She's going to come, too.

Midong High's Korean teacher.

- She also lives in Taebaek. - Really?

That's good. As a matter of
fact, I have to drop by school.

Lee Dong Jin.

What's this?

Explain what's going on if
you've called up all your friends.

You left your hometown. So
why are you back all of a sudden?

Did something happen?

I'll tell you tomorrow when we all meet up.

Big data.

I must extract the essential
information from here.

(Special thanks to Kim Young
Woong and Hyun Bong Sik.)

Since 2014, everything
has been digitized...

and stored only on the server.

But back in our days,

a lot of records were still handwritten.

Most of what you need should be here.

That house. Near that house.

Yes, right here.

(Jeongun-ri)

Did anyone get injured or die in this area?

Is it even possible?

Of all times and places,
a wild boar was there.

I know it's strange.

But I came to ask about when
you were stung by a wasp.

A wasp?

We haven't seen each other in ages.

But why would you bring up the Witch?

So...

you still call her Witch.

The accidents that occurred here...

are concentrated primarily
in 2010 and 2012...

when Park Mi Jung was enrolled.
