So, in my opinion

I think this series has a genius setup.

- What do you mean? - Just look at this.

Someone took my hand.

And you can't even recharge.

But why do we touch each other?

Why do we hold hands?

Why do we kiss?

Why do we touch mucosa?

Hello? This is Orbit from "Deep Dive."

Today, we have some special guests with us.

We have actors Chae Soo-bin and Kim Young-kwang with us!

Hello, I'm Kim Young-kwang.

In the Netflix series "Take Charge of My Heart,"

I play a man whose heart runs on a battery

who's called Baek Horang.

And here we have the drama writer

Na Bobae joining us.

Hello?

I'm Chae Soo-bin, playing the role of Na Bobae.

Bobae can't physically touch people.

Because electricity flows through her.

So, she's single since birth, but

she's a character who writes romance stories.

First of all, Soo-bin has appeared, but

the whole idea of her being single since birth is

pure fiction.

Honestly, more than the scientific content

the fact that Soo-bin is single since birth is fiction.

But here you are with the series "Take Charge of My Heart."

This series incorporates a lot of scientific elements.

Are these scenarios and settings really possible?

I invited these two to unravel this for you.

There are various things to discuss, right?

The most important thing is that Bobae is the starting point, right?

What's her situation like?

Bobae was struck by lightning on her way home from school at age 8

and since then, her body developed abnormalities.

Electricity comes out, shocking her family too.

It's quite an interesting situation.

Let's start by exploring if you can survive a lightning strike.

Lightning strikes young Bobae, right?

Yes, the first question.

What is lightning?

We need to solve this first.

What exactly is lightning?

Electricity?

Young-kwang, you're amazing!

As expected, you're incredible.

To put it simply, in the most basic terms

it's a massive static electricity discharge that occurs in the sky.

It probably started from here.

The production team of "Take Charge of My Heart" definitely knows their stuff.

Why?

Because from then on, they unravel stories related to static electricity.

So, actually

it's not about whether Na Bobae's powers are static electricity.

We need to distinguish them separately.

But they deliberately show activities that look like static electricity.

By continuously showing them

the fact that the production team knows about static electricity discharge

they're subtly showing off their knowledge.

So, they're hiding it like this.

So, this is static electricity discharge.

How does lightning strike?

Inside a thundercloud

there are ice particles and water droplets.

As they collide and move, friction occurs.

So, when we have ice and water droplets

which one would rise higher?

Ice and water droplets?

Ice and water droplets.

If you think about it

when it comes to coffee

what's on top in iced coffee?

- Ice. - That's right.

Generally, solids are heavier and expected to be at the bottom, but

water behaves unusually when it becomes solid.

It expands and becomes less dense.

So, in iced Americano, the ice floats to the top.

So, as ice particles collide with water droplets

they rise upwards

stripping electrons from the water droplets as they rise.

The top of the cloud becomes positively charged, and the bottom becomes negatively charged.

Then, as the negative charge at the bottom increases its potential difference with the ground

so, as the gap increases

this massive static electricity discharge suddenly strikes

breaking through the air, which acts as an insulator.

But according to the National Weather Service, a typical lightning strike

has a magnitude of about 300 million volts.

What do you think happens if you're hit by 300 million volts?

- You die. - It doesn't feel good, does it?

300 million volts, just the thought of it.

But there's a surprising statistic.

According to the CDC in the U.S., among lightning strike victims

90% survive.

Really? Quite a lot survive, huh?

Even though lightning has immense voltage and current

because the duration is short...

And the biggest cause of death from lightning is cardiac arrest.

So, this is quite interesting too, isn't it?

The character Na Bobae who was struck by lightning, in reality

the most dangerous thing about lightning is cardiac arrest

and since we're talking about the heart

this scenario is plausible, isn't it?

So, because the likelihood of cardiac arrest is high

when struck by lightning, cardiac arrest occurs

and immediate CPR increases the survival rate.

So, the chance of survival for Bobae is very high

and hence the character setting of Na Bobae itself is very scientific.

What do you call it when someone is struck by lightning?

- What do you call it? It leaves scars like this. - That's right.

That's possible, right?

So, this was actually foreshadowed earlier, wasn't it?

There are some lightning marks on Na Bobae's upper body.

This is called a Lichtenberg figure.

- I think our Soobin might have heard of this, right? - That's right.

Red patterns spread on the skin like branches or ferns.

These aren't typical burn scars.

So, according to medical literature

they're more like temporary skin changes.

What this means is, because they're not burns

they usually disappear within hours to days.

- Really? - Yes.

But in the drama, it's portrayed like a Lichtenberg figure.

There's a scar like this.

So, the production team

knows about the Lichtenberg figure.

They're informing us about this.

They want the audience to notice it.

There's a bigger issue here.

It's possible to be struck by lightning and survive

and they intentionally included the scars like this.

The problem is, why does electricity keep coming out afterward?

We need to solve this.

It's because a superpower has developed.

So, we need to solve this.

- Because Na Bobae was struck by lightning. - Right.

But does that stay in the body?

Does a person struck by lightning become a giant battery?

No, that's not the case.

Because the lightning current flows and passes through instantly.

So, after the victim is struck by lightning

it's not like the rescuer gets an electric shock by touching them later.

It's already passed through.

To make Bobae's abilities realistic

is the electricity from a childhood lightning strike still in the body?

It's difficult to see it that way.

- It's a superpower. - Right.

But those buildings

- you know, those lightning rods? - Lightning rod.

Don't those things store electricity?

The lightning rod carries it down and disperses it somewhere else

usually grounding it into the earth.

Can't it be stored?

It's not easy to store it

and if you want to store it to charge something

there's a complex process, and it's dangerous, isn't it?

So, a being like Bobae can't exist in reality?

So, we need to solve this.

I'll solve this for you.

Does the lightning electricity remain?

So, the energy Boba is using now

is it from a childhood lightning strike?

We need to resolve this.

Scientifically, this is difficult.

But don't worry, I'll solve it for you.

I'll take care of this for you.

It's hard to believe it remains.

But as a result of being struck by lightning

the body could develop a new function to generate electricity.

That's how we should see it.

Is that possible?

We need to see if it's possible, right?

So, strictly speaking, it's more like a power plant than a battery.

That's how we should see it.

So, is this really possible?

In the story, people tease the character by calling her Pikachu

but in reality, long before Pikachu

there are animals that have developed electric abilities.

You might know, when you think of electricity...

- An eel? - That's right, electric eel.

That's good.

A species of electric eel reported in 2019

was measured to discharge up to 860 volts.

That's a really high level, isn't it?

Because if it's 860 volts

have you ever been hit by a Taser in anything you've filmed?

- I've never been hit by one. - Just in case.

Because there are cases where people do get hit, you know.

I asked just in case, but

a Taser is 400 volts, you see.

But 860 volts is more than double that of a Taser.

It's powerful, right? Really powerful, but

how can a living organism produce 860 volts of voltage?

There are these things called electric cells.

Electric eels generate electricity within their bodies

with thousands of specialized cells arranged in series.

So, the voltage each electric cell produces

is only about 0.1 to 0.15 volts.

It's really small, isn't it?

But they stack thousands of these cells in series.

So, if you connect batteries in series

the voltage goes up, right?

Just like that, they gather a little bit of voltage from each

and drastically enhance the electricity used by nerves and muscles.

The electric eel uses it as a weapon.

Then we could reimagine Na Bobae as an electric eel.

Teasing someone by calling them Pikachu

because Pikachu generates electricity directly, right?

But you store it with an auxiliary battery, right?

So, Baek Horang is very

competent in business but a bit lacking in science.

The character setup isn't for Young-kwang, though.

But Na Bobae and her acquaintances and family

already have some understanding of

the concept of Pikachu itself.

So, Na Bobae also has electric cells like an electric eel

and an electrical organ connecting those cells in series.

That's how you should see it.

In 2026, there was a report on using genetically engineered human cells

in a biohybrid power generation system.

It's possible to generate electricity, you see.

So, what's the slightly unrealistic part here?

Generating electricity is scientific.

Now, the scale of generating electricity

involves a bit of creative, artistic license from the creator.

So, if electricity could be generated in the human body...

It could be possible.

Is the voltage strong enough to charge a car?

Is it that level?

That's the issue.

So, these electrical phenomena do occur in our bodies.

But unlike electrons flowing through copper wires

it's a bit different from that kind of electricity.

Our bodies are actually biorobots powered by electricity.

We continuously generate electricity.

So, although it's very small

there's a bit of Pikachu in us.

- We also generate electricity. - "The Matrix."

It appears in the first one, right?

The machines dominate the world...

Human biological batteries.

- Right? - Yeah, that's right.

- Right, you've seen it, haven't you? - That's right.

That's how it is.

That's how they use them as batteries.

Humans become obsolete

so by putting humans in as biological batteries

- the machines use this electricity, right? - That's right.

But does it actually produce a lot?

This needs to be looked into.

When we get an electric shock, you know?

When you get an electric shock, you can't move, right?

That's because we move with electricity.

The brain sends out electricity to make us move, but

if strong electricity flows, the brain's commands are ignored.

For example, if you fan during a typhoon

it's like you can't feel the fanning.

So, when you get an electric shock, you can't move.

Just like this, we actually generate electricity in our bodies.

But this electricity isn't for powering machines.

Nerves send signals, and muscles receive them to move.

The heart uses electrical impulses to regulate its rhythm.

The body's bioelectricity is more like...

What is this, really?

It's closer to a communication line.

So, holding electricity like this

if you hold a bulb here, will it light up?

Holding electricity on this side?

If you hold electricity, it might light up.

But!

It's better not to try it.

That's not using your body for communication

it's just using your body as a conductor.

But you know those things, right?

When you look on Instagram, how did those two people do it?

Did they rub something?

After doing something

when both of them touch the bulb like this

you know, it lights up with a click.

- So, are all those things fake now? - Of course.

Most of the stuff on SNS is staged.

If you're curious about this kind of stuff, feel free to send it to me later, seriously.

- What's that about? - That's a good question.

So, let's move on to the topic of static electricity.

It's that tingling sensation we feel.

So, does that mean our bodies can generate electricity now?

It transmits information similar to communication.

But is static electricity the same as bioelectricity?

Not exactly.

It's like when you touch someone in winter and get a zap.

And in the drama, it keeps zapping, right?

This is mainly static electricity.

When different materials come into contact and then separate, electrons move, and electric charge builds up on the body.

When something with a different electric potential gets close, like another person

then the electric charge moves suddenly.

It's similar to lightning, isn't it?

The gap widens and then suddenly discharges.

So, static electricity is like a small lightning bolt.

Even the Korea Meteorological Administration says, 'In dry winter conditions, static electricity occurs easily.'

They say it's because there's not enough moisture, so the electric charge can't escape easily.

The gap widens and when they meet, it discharges suddenly.

That's why static electricity occurs so frequently, static electricity.

For people like this, it's due to dry skin and clothes or repeated friction.

That's how static electricity is generated.

So, Bobae is a really dry person, huh?

That's right, exactly.

Maybe it's because of a past lightning strike

now, the skin or environment has become a bit dry.

Then, apply a lot of moisturizer, or...

- You need to moisturize a lot. Moisturizing can definitely solve it. - Because you didn't moisturize...

If you look, you can see she doesn't use hand cream often in the drama.

So, including this static electricity is a scientific element hidden by the creators.

It's not to show that I'm storing electricity in my body.

So, does getting struck by lightning make static electricity occur more easily?

There's no known biological mechanism for this, but

originally, Na Bobae is someone who easily generates static electricity

and because she was struck by lightning as a child, people around her connect the two.

It's possible, you know.

Anyway, they included the element that static electricity occurs easily, right?

So, even on the bus, you worry about bumping into people and feel the tingling when you touch them.

So maybe including static electricity isn't to imply that Na Bobae has electrical energy

but is a device to show that she's an active generator.

So, is Bobae's body a battery?

- Or is it a generator? - Exactly.

So

actually

Baek Horang stores it as a backup battery, right?

That's right, it's stored here.

The scientific misunderstanding of these terms also shows their characters.

So, a battery uses pre-stored energy.

But a generator converts other forms of energy into electricity.

So, it's not like she got struck by lightning once as a child and has been using that electricity for over 20 years.

- She's more like a generator that continuously produces new electricity. - That seems to be right.

Because Bobae doesn't recharge, right?

- It just keeps coming out. - That's right.

And what's interesting is, you mentioned recharging, and I'll address that later.

How does she keep generating electricity continuously?

So, Bobae is actually a human generator.

But you asked a very important question, from a thermodynamics perspective, energy doesn't come for free.

So, if Bobae, for example, sends out 100 joules of electrical energy to charge Horang

then a significant amount of energy must come in from somewhere else.

In the case of an electric eel, it doesn't create energy for free either.

This one, oh, I mean, this electric eel

to create and maintain ion concentration differences, metabolic energy is needed.

So

realistically, if Na Bobae were a generator

after using a lot of electricity, she'd need time to recover because she'd be hungry or tired.

But she does eat well, right?

That might also show the process of recharging with food and sleep.

And if you notice, Na Bobae is always tired.

- That's right. - That's because she's generating electricity.

- She's always a bit tired, always lying down, right? - She's always lying down.

- Isn't that her true form? - That's also the creators

- who set it up with scientific understanding. - Even in the drama, it gives off that kind of vibe.

- Is Bobae always lying down? - She's often lying down.

Her head is always tilted, right?

- It's because she's generating electricity. - Yeah, there was a reason for everything.

We should've met in advance, then

- when you were acting... - Exactly.

- Anyway, you're acting based on direction. - Yes.

- If you had understood this and acted, you would have realized you were recharging. - Indeed.

In the drama, it's already well expressed. The direction was spot on.

You get it, right? That's why she's tired and eats well, right?

That explains it.

That's right, but when Na Bobae encounters a discharged elevator

she recharges it with her finger to get it running again.

- Is that even possible? - Of course.

Certainly.

As for the process of transferring electrical energy to the elevator, naturally

it's considered artistic license.

Let's just focus on this.

In the story, can Na Bobae generate enough electricity to recharge an elevator?

To do that, she'd have to surpass an electric eel by far.

She even powers the surgical room lights.

That requires a significant amount of power too.

But an elevator needs even more.

An elevator requires kilowatt-level mechanical power output instantly.

So, Na Bobae powers not just a few hospital lights but the entire facilities.

She even gets the elevators running.

Then it's not just ordinary human bioelectricity, it's more like a small power plant.

That's impressive.

As I mentioned earlier, to move an elevator

you need kilowatt-level power, and it's not just about high voltage.

So maybe Na Bobae's ability isn't just about high voltage

but maintaining a large current stably over time.

- Yes. - I have a question that just popped up.

- You said an electric eel generates electricity to attack, right? - Yes.

But is the strength of that attack the same for all of them?

Or

is there a difference among each one?

Some are good at it, and some aren't, right?

That's generally how it is.

As I mentioned earlier

there's a type of electric eel that can generate over 800 volts.

There is a species of electric eel like that.

They're more than just eels that generate electricity to attack.

They're a kind of renewable energy.

That's what they are.

What I found a bit disappointing was

the fact that humans can generate this level of energy could be a powerful key to overcoming the climate crisis.

So, it's not the time to be charging Baek Horang's heart.

Being embarrassed about being like Pikachu

instead of fearing static electricity, you should really start helping people.

- You should share love, right? - You could be a hero.

Completely, just

someone who can save the country, overcome the climate crisis, and achieve carbon neutrality.

Because you just eat and generate energy.

This is a revolution, especially at this point of climate crisis.

The keyword to overcoming global warming is now Na Bobae.

It would be great if this aspect comes out somewhere later.

If it goes to Season 2

Season 2 could involve national-level issues, wouldn't that be fun?

Then, is there a way to deliver an electric shock without touching?

This part came up when, as a child, she screamed at a cockroach

and electricity spread around without contact.

What is this? If this is possible, it's close to an air discharge, an arc discharge.

What's interesting is that it's similar to Pikachu's method.

Pikachu also shoots Thunderbolt with a pika-pika, right?

But the problem is, to create an arc discharge like a Thunderbolt

Pikachu's range is really short, just a few centimeters.

So when it does a pika-pika Thunderbolt, it attacks right up close, actually.

So to shoot it far, it needs to be much stronger

which involves some creative allowances.

But

Bobae can generate visible discharge to someone a few centimeters away

and keep sending noticeable discharge that leaves a mark.

She has a structure in her body that can create tens of thousands of volts of electric potential

which means she has considerable power at the same time.

A mobile renewable power plant.

That's pretty clear, isn't it?

So, for the character I play, Baek Horang

if the heart runs on a battery and you check its charge level with a smartwatch...

Yes, this is quite realistic too.

So, does it have Bluetooth?

- And Wi-Fi like this? - The signal...

Right, there's something connected to measure the signal.

First, with Baek Horang, it's interesting that you need to make distinctions.

You need to distinguish between a pacemaker and an artificial heart.

Of course, there's one more thing, but

a pacemaker is a device that assists the heart's electrical timing without replacing it.

But there's a ventricular assist device in between.

This mechanically aids the blood-pumping function of a weakened ventricle.

But here, Baek Horang has an artificial heart, right?

An artificial heart replaces the heart's pumping function much more directly.

So, it receives power from an external battery or power source.

When the battery gets very low, warnings appear in stages.

Because it's mechanically assisting, it can't stop, right?

So, according to the manual, a warning appears at about 15 minutes.

When there are only five minutes left, a higher-level warning is set, they say.

Yes, so...

- Is there really an artificial heart? - Yes.

Maybe if you replace the battery inside once

it could last quite a long time, even until death, these things are a bit more

of a near-future setting, but it's scientifically plausible.

So, like Horang, living a life where you check 'What percentage is my heart's battery at now?'

This is realistic.

Of course, the UI on the wristwatch might be different, but the state of the internal pump

the idea of checking the remaining external power from outside the body is already a reality.

Then, in case of the artificial heart

even if the battery is just nearby like this

can it charge?

Right, from here, the series' setting becomes really intriguing.

There are three stages of charging for Bo-bae and Horang.

When it's like this, at about ten meters

- it charges by 1% every few minutes. - It's a bit of a slow charge.

- When you start touching, or rather... - Hey...

Where are you touching?

- If you hold hands. - When your hands touch.

- When they touch. - It charges a bit faster, like when you hug or something.

In the series, the mucosa...

- The mucosa is scientific. - When the mucosa touches

- it becomes fast charging. - That's right.

Yes, it can be divided into three stages.

If you're close, it's a bit of a slow charge, but when skin touches, it's faster

and when the mucosa touches, it's rapid charging.

- There are cases where the mucosa touches, right? - Yes.

Yes, let's break this down scientifically one by one.

First of all, when you're far away, not too far, though

you can still charge Ho-rang even from a little distance.

Here, actually

it's not static electricity, but wireless power transfer.

It's something that requires a specific mechanism, but you use wireless charging in real life, right?

- Yes, we do. - Yes, when you look at wireless charging

- you have to align it to a certain position for it to charge, right? - Yes.

If you just place it carelessly, it won't work well.

Just like that, wireless charging itself isn't simple, and if you were to make Bo-bae scientifically

you'd have to align precisely within a few centimeters, and you can't move.

So, they have to stay like this for quite a long time.

For example, if you take a step?

Then again...

- Does the connection break? - That's right, the connection breaks.

Because wireless charging is that difficult.

So, whether to transmit the energy directly

does the Na Bobae generator really transmit wireless power?

When you look at it this way, it becomes difficult to explain.

Because even in a hospital room, things move around while charging, right?

But she still charges, you see.

So, how does this work, I wonder?

Let me reiterate, when viewers are watching

you can just take it easy and understand it simply.

You can just think of it as sending electrical energy.

But if you delve into the science a bit more

it becomes even more interesting.

There's no problem with understanding or watching it.

You can interpret this work however you like.

So, at first, I thought she was sending energy like this.

But is she really sending energy from here?

If she is sending energy

you wouldn't be able to move around while charging.

So maybe at this point, it's not energy, but

it's information.

She's sending information.

That's how I've concluded.

She's only sending very small signals.

Baek Horang already has a power generation system.

Because Na Bobae is a generator.

Baek Horang also had some potential as a generator.

But it's not activated yet.

But only Na Bobae, who has experienced lightning, is activated.

That's what got activated, right?

Na Bobae knows it.

How does my body use bioelectricity?

I know how to generate power.

Then Bobae uses electrical signals to

activate Baek Horang, like a kind of trigger.

- Isn't it interesting? - Yes.

Then it's not electricity.

So it's not charging with electricity.

It's information, so it's not "Take Charge of My Heart."

It's more like, "send me the information so I can charge."

This is the accurate explanation, but it's getting too long.

But then, instead of when they're apart

what's the reason he charges faster when they touch skin-to-skin?

That's another great question.

We need to look at it from the perspective of human skin.

Skin is actually a very good insulating layer.

In other words, skin doesn't conduct electricity well.

So the outer layer of skin, the stratum corneum, greatly increases resistance.

So on dry and intact skin, resistance can be very high.

When considering that contact also conducts electricity

there are many challenges.

Because it's such a good insulating layer.

Sending electricity through it

is a bit difficult when the skin is in contact.

But we understand it as information, right?

So, assuming information is transmitted as an electrical signal

being close obviously allows for more efficient transfer than being far away.

You can send more information.

So, it can accelerate the temporary activation of Baek Horang's bio-generator.

So, when information is in direct contact

it's transmitted much more efficiently.

Looking at it this way, it aligns with physical intuition to some extent.

In the same context, what's the third stage?

- Mucosa. - Mucosa.

When you say mucosa, it might not evoke any feelings

but when you think about it between lovers, it gets a bit complicated.

In the same context, when mucosa touches each other

the resistance naturally decreases.

What am I saying?

Skin is a very good insulating layer, right?

But the more moist it is, the better it conducts electricity, right?

Mucosa is much more moist than skin.

When these things touch each other, the resistance decreases

so naturally, rapid charging

rapid information transfer is possible.

I think this series has a genius setup.

- What is? - Look.

It transfers information indirectly without contact.

The skin touches.

The mucosa touches.

If you just look at this scientifically

'Of course, since the resistance decreases, it transmits well,' you might say.

When you look at the stages, it's quite romantic.

The drama connects scientific facts with romance.

This is truly genius.

The more romantic it gets, the faster the charging.

It utilizes the fact that it becomes more efficient.

The romantic charging stages in the work actually reflect the intimacy levels between couples.

At the same time, it's also the stages of the electrical coupling coefficient.

So, the distance between people

and the distance between circuits

these two stories are being told simultaneously.

This is a really clever setup

and visually, it's very pretty too.

So, let's change the question and try it in a real-world context.

If you think about what actually happens between people

you'll see a new fact emerge here.

Someone held my hand.

It's hard to say that information is being transferred to me.

It's just holding hands, right?

It doesn't result in charging either.

But why do we make contact?

Why do we hold hands?

Why do we kiss?

Why do we touch mucosa?

What do you think?

It's a sense of stability.

A sense of stability.

What's interesting in this drama is... look at these keywords here...

Contact

heart

these keywords are included, aren't they?

When you make contact, it doesn't result in charging.

But the heart changes, the heart does.

It beats faster.

Actually, information is coming in.

So, the setup of this work is very scientific.

My brain reads this contact.

And so, who this person is

whether they're safe, dangerous, or someone I like

or if it's unwanted contact.

For example, when I make contact with someone I like

there are many things I feel.

When I'm really tired

a person I like shares good news with me

and I receive comfort from someone

and someone gives me a hug

what happens then?

You gain the strength to move.

So, at this time, it's not physical energy that's generated.

It's not that electrical energy is being controlled.

The first law of thermodynamics doesn't make exceptions just because you're in love.

What's changed?

It's about how you use the energy your body has that's changed.

A person sends a huge amount of energy to another person, or

without needing to send information.

Even with just a tiny bit of information

you can adjust the energy system that person already has.

So what I'm telling you now is completely scientific, you see.

When you touch, it creates changes in the autonomic nervous system, for both.

This is the development of Boba and the charging of Horang's artificial heart.

It's very similar to the imagined system.

Transferring information to create some change.

This is the setting of the "Take Charge of My Heart."

It's eerily similar to actual science.

- That's right. - So if it goes like this

the fantasy of this series completely enters reality.

Maybe by transferring information

the situation where Baek Horang can use more energy is very realistic.

It's very realistically well-made.

A project containing neuroscience settings

this is the drama "Take Charge of My Heart."

Isn't it amazing?

- Yes. - Very scientific...

This should be classified as SF.

It's hard sci-fi.

So let's think about the meaning of this drama.

It was clear at the beginning.

Simply put, Bobae charges Horang, right?

A person with electricity charges a person who needs a battery.

Precisely, Na Bobae is the provider.

Baek Horang is the recipient, right?

But as the story progresses, that distinction becomes blurred.

Horang needs Bobae's electricity.

Bobae needs someone who isn't afraid of her.

Someone she can touch is needed.

So one person receives what's necessary for life support.

The other receives what is necessary to maintain a relationship.

So if we go back to the title

we usually think of "Take Charge of My Heart" as Horang's words.

But it can also be Bobae's words.

So "Take Charge of My Heart"

is a title that perfectly fits each of the characters.

To Horang, Bobae wasn't a person at first.

She was a survival device.

And in Horang's case, he's never depended on anyone his whole life.

A flaw called an artificial heart

this flaw has always been a stumbling block for Horang.

The moment Bobae appears

all these crises are resolved, right?

But Bobae, on the other hand, has always seen her body as a risk factor.

But the lifelong flaw Bobae thought she had

becomes the first and only need for Horang.

So charging is not something that only happens to Horang.

Horang receives electricity

and Bobae receives a new meaning for her body.

The setup where each person's flaw is the other's necessity...

Is there anything more poignant than this?

In this world, they only need each other.

So I'll wrap it up here.

"Take Charge of My Heart."

The most scientific aspect here is

it's not about humans generating electricity.

It's about a person generating electricity to charge another.

But the truly important setup here is

how one person can impact another

and can truly make our hearts beat differently.

So, how was it today?

It was really fun

and I feel like I've gained a deeper understanding of Bobae.

It was really nice to learn more

and the way you beautifully presented the story of the two characters

was so beautiful and impressive, I was really moved.

Thank you.

But now, have you fully understood the setting?

Should we reshoot?

Is the filming all done?

The filming is all done, right?

If I ask you to do it again, would you?

You won't do it, will you?

Now that filming is done, should we move on to Season 2?

Now that you understand the setting...

Sounds good.

I also discovered something today.

As I was reflecting on what I knew

in the world of "Take Charge of My Heart"

there are parts that I now understand.

So it was really fascinating.

When we were filming, we didn't delve that deep

like, scientifically transferring information transfer

we're each other's generators, etc.

I don't know about this part

but as I kept listening, it started to make sense.

This is really quite fascinating.

It was incredibly fun

and it was so refreshingly original, I loved it.

In a project, if one plays the role of a scientist

or when acting in a science-related role

even if one doesn't understand it 100%

even if one understands just enough to accept it

the character becomes richer.

- Exactly. - That's right.

So, having this opportunity at the end

being able to give this explanation is an honor for me too.

Up until now, we've been with our actors

Chae Soo-bin and Kim Young-kwang of the Netflix series "Take Charge of My Heart."

This was Orbit from "Deep Dive."

Thank you.
