Take Charge of My Heart: how Chae Soo-bin and Kim Young-kwang make an old setup click

Kim Young-kwang plays an heir whose artificial heart is running out of battery, and Chae Soo-bin plays the writer whose electric touch can recharge it.

01Baek Ho-rang and a heart on a dying battery

Take Charge of My Heart is Netflix's Korean rom-com built on one strange image: a man whose heart runs on a battery that is almost empty, and a woman whose touch is electric. On paper, it is the oldest setup there is. The interesting question is what makes these two leads click.

Kim Young-kwang plays Baek Ho-rang, the third-generation heir of a chaebol family and an executive at TS Resort. He is a perfectionist and a workaholic, the kind of man who handles everything well and makes it look easy. But inside his chest is an artificial heart, and its battery is dying.

The man who seems to have everything is quietly running out of time.

Kim Young-kwang said the script brought back the excitement of the romance comics he read as a child, and he wanted to bring it to life the moment he read it. He also knew the rich-heir role invites comparisons, with so many before him. So instead of playing it big, he went calm and understated, and focused on making Ho-rang feel real. He even designed Ho-rang's styling himself, so it would shift with every situation.

Director Park Soo-won called him the ideal male lead, someone who can move easily between sharp and affectionate. But a man this careful needs someone who can get through to him.

02Na Bo-bae, the writer whose touch is electric

Chae Soo-bin plays Na Bo-bae, a cheerful TV drama writer who was struck by lightning. Since then, a jolt of electricity runs through anyone she touches.

So she writes love stories for a living… but she has never had one of her own.

Chae Soo-bin said Bo-bae tries hard not to bother anyone, sometimes covering up completely, or wearing a single glove. And her curly hair is the static electricity, her own small detail for the character.

Then she meets Ho-rang, and for the first time, nothing happens. He is immune. Director Park Soo-won described Chae Soo-bin as magnetic and lovely, and Kim Young-kwang said they laughed constantly on set, with her natural comedy making his own role easier to play. The pairing has a neat symmetry: the one person her spark can't hurt is the one person who needs it to live.

03The role Chae Soo-bin almost turned down

Chae Soo-bin almost said no. The Korea Herald calls her a rom-com queen, and that was exactly her worry. She was afraid that being known for romance could close the door on other kinds of roles she has long wanted to play.

What changed her mind was the team's confidence, and the warmth she felt in the project. The director, the writer and the production head told her it was a familiar taste, and they were sure they could make it very, very good. When she finally read the script, she found it lively, charming and warm. She decided that even a familiar story could still feel special.

04An accidental kiss and a contract

An accidental kiss and a strange moment at a hospital reveal what is going on: her touch recharges his heart. He needs her to stay alive. And she, for the first time in her life, can touch someone without hurting him. So they make a contract.

If you have watched K-dramas for a while, you know where a contract like that usually goes, and the makers know it too. Director Park Soo-won said the goal was never to reinvent the genre, only to give its familiar beats a fresh spin, and she believes that familiarity works in the show's favor.

What hooked her first was the heroine's electricity, because the hero falls for her precisely since it doesn't affect him. The one thing that keeps everyone away from her is the one thing he can't feel. And the idea of charging is what drew her to the story. Everyone, she said, reaches a point in life when they need to recharge. She hopes viewers either long for that kind of recharge, or see the value in recharging someone else.

05Now, the numbers behind the climb

In its first three days, the series reached number three among non-English shows, with three million views. That first week, it made the top ten in forty-four countries. Then, instead of fading, it climbed. In its second week it rose to number two, with 6.4 million views, more than twice its opening. And in its third week, it was still in the global top ten, at number seven.

The story began as a web novel on Naver, and the series was written by Song Yu-chae. The director believes viewers around the world now see K-dramas as a reliable package of conflict, comedy and romance. And all ten episodes are already out.

06So why do these two click

What is new here isn't the formula, it's the feeling. He needs her to keep his heart beating. She has spent her life keeping people at a distance, and finally, someone can hold her hand.

Chae Soo-bin called it a story that feels warm and comforting to watch. Kim Young-kwang put it even more simply: a dreamy story, where comic-book fantasy becomes real.
