Take Charge of My Heart Cast, Characters and Netflix Romance Explained

Who stars in Take Charge of My Heart? Kim Young-kwang plays Baek Ho-rang, a corporate heir kept alive by an artificial heart, while Chae Soo-bin plays Na Bo-bae, a romance writer who unintentionally shocks anyone she touches. Cha Woo-min, Jung Jae-kwang and Shin Do-hyun are also among the reported cast. The Korean fantasy romantic comedy is scheduled to arrive on Netflix on October 9, 2026.

It sounds like the beginning of a particularly outrageous meet-cute: he is running out of power, and she has enough electricity to hurt the people she wants to hold close. What makes the premise interesting is how both characters have learned to live without something most people take for granted. He cannot let anyone discover the weakness behind his perfect executive image. She has never been able to enjoy ordinary intimacy without fear of causing pain.

This spoiler-free guide separates what Netflix has officially confirmed from additional cast reporting and our interpretation of the trailer. With the premiere still a day away as of October 8, it does not pretend to know the ending, unannounced twists or characters’ eventual decisions.

What is Take Charge of My Heart about?

Baek Ho-rang seems to have everything a modern K-drama hero is supposed to possess. He is a third-generation heir to a powerful conglomerate, a sharp strategist and an executive running one of the company’s major resorts. At work, being composed is practically part of his job description. Beneath the immaculate public image, however, he lives with an artificial heart whose battery is becoming dangerously unreliable.

Na Bo-bae has a secret of her own. A childhood lightning strike left her with an extraordinary electrical ability. Her body can deliver a jolt through physical contact, so the simplest romantic gestures have become hazards. Wearing gloves and maintaining her distance are not stylistic choices. They are the practical habits of a woman trying not to hurt anyone.

Their first meeting begins with an accidental kiss. Bo-bae discovers that Ho-rang is the rare person who can touch her without suffering an electric shock. He does not immediately welcome this discovery. But when a storm-related blackout disrupts a procedure to replace the battery in his artificial heart, he finds that proximity to Bo-bae can restore its charge.

Suddenly both have a reason to stay together. Ho-rang needs to survive for roughly three months until another operation can take place, with a business succession battle also approaching. Bo-bae is racing against the end of her writing contract and urgently needs real romantic experience to create a convincing love story. He proposes a bargain: she will help recharge his heart, and he will help her complete the romantic experiences she has missed.

The setup is deliberately playful, but there is an emotional question underneath it. When someone becomes essential to your survival, how do you know whether your attachment is love, gratitude, obligation or fear of being alone? That is the unresolved tension on which the show’s advertised romance depends.

Meet the five key actors

Kim Young-kwang as Baek Ho-rang

Kim Young-kwang leads the romance as Baek Ho-rang, a businessman whose apparently effortless control masks an extraordinary medical vulnerability. He is not simply a billionaire with a secret. The upcoming leadership contest at TS Group gives him practical reasons to appear invulnerable to rivals, while his artificial heart makes any delay or failure potentially catastrophic.

Netflix describes Ho-rang as intelligent, strategic and skilled at getting things done. Those qualities are likely to serve him badly when he meets Bo-bae, because a romance is not something he can manage like a corporate deal. His first instinct is to avoid her; his second is to negotiate. Neither response guarantees that he understands what she wants.

Kim Young-kwang is familiar to Netflix viewers from Somebody and Trigger, while the film On Your Wedding Day shows his connection to romantic storytelling. At a press event reported by The Korea Times, the actor discussed trying to ground the wealthy-heir archetype in believable emotion. That approach is important for a series asking viewers to accept a comic-book science-fiction device without losing sight of its human stakes.

Ho-rang’s appeal will likely depend on whether he learns to treat Bo-bae as a person rather than a portable solution to his problem. The teaser promises the awkwardness of two people who need to touch for a practical reason but have not yet learned how to be emotionally open.

Chae Soo-bin as Na Bo-bae

Na Bo-bae is the story’s literal source of electricity and, potentially, its emotional center. She is a romance writer who struggles to write about intimacy precisely because she has had so little safe experience of it. The contradiction gives the premise a strong comic engine: the woman paid to imagine love has to negotiate for the chance to practice it.

Bo-bae’s gloves also offer a useful visual shorthand for the character’s isolation. A touch that seems insignificant to others could be frightening for her. When she discovers that Ho-rang can withstand it, the encounter opens an entirely new possibility. He is not automatically her soulmate, but he is the first person who makes ordinary closeness feel imaginable.

Chae Soo-bin previously starred in Netflix’s When the Phone Rings and The Fabulous, and many K-drama viewers also know her from I’m Not a Robot, another romance that mixes unusual premises with questions about genuine connection. The new role gives her room for embarrassment, determination and humor as Bo-bae attempts to turn her imaginary romance checklist into real life.

Netflix’s announcement says her writing contract has only three months remaining. That deadline gives her equal narrative urgency rather than making her merely a helper in Ho-rang’s medical emergency. The most satisfying version of this story would allow both characters to ask for what they need and decide freely what their closeness should mean.

Cha Woo-min as Ji Eun-ho

Cha Woo-min is credited as Ji Eun-ho, a successful star and Bo-bae’s devoted fan. SBS’s trailer report places him in a possible romantic triangle with Bo-bae and Ho-rang. Unlike the two leads, Eun-ho is not bound by the battery-recharging contract, which could make his attention especially important to how Bo-bae understands choice.

The distinction between being wanted and being needed is central here. Ho-rang has an urgent physical reason to seek Bo-bae out; Eun-ho’s interest may introduce an alternative, though the series has not yet revealed how that competition will unfold. It would be premature to assume a villain, a final couple or a major betrayal from a brief trailer.

Cha Woo-min has appeared in Melo Movie, Night Has Come and Study Group. His role adds recognizable youthful energy to a show already balancing fantastical mechanics with a familiar romantic-comedy triangle.

Jung Jae-kwang as Choi Do-yoon

Jung Jae-kwang, also romanized Jeong Jae-kwang, is credited as Choi Do-yoon. The character appears among the named supporting players in recent SBS publicity, but the official premise has not supplied enough information to describe his profession, allegiance or connection to the central contract in detail.

It is reasonable to expect the supporting ensemble to widen the story beyond the couple’s private bargain, especially since Ho-rang has corporate and medical pressures and Bo-bae has a professional life of her own. However, attaching a specific secret, romance or betrayal to Do-yoon now would be speculation rather than a cast guide. His precise role is one of the details to revisit after release.

Shin Do-hyun as Han Seol-hee

Shin Do-hyun appears in secondary cast listings as Han Seol-hee. She has previously worked in Hospital Playlist and Doom at Your Service, which should make her familiar to viewers of character-driven Korean dramas.

Her appearance in publicity suggests that Seol-hee contributes to the emotional or social world around the leads, but little has been established publicly about the character’s motivations. Some casting reports classify the part as a guest role. Rather than inventing a rivalry or kinship connection, it is more helpful to keep that status clear until the series itself introduces her.

Why the three-month countdown matters

Both protagonists are on a clock. Ho-rang needs enough charge to reach another surgery; Bo-bae has to produce a convincing romance before her writing agreement ends. Making the deadlines match is more than a convenient plot device. It gives the pair an agreed period in which to suspend normal routines and behave as if their unlikely arrangement makes sense.

That deadline can also make every small moment feel more consequential. A hand held today may have been a practical necessity, but what does it mean when they begin to anticipate it? A date planned to help Bo-bae write a scene might become a memory she would not want to lose. The trailer’s physical comedy makes space for those emotional changes without requiring an early confession.

The tension around TS Group means the relationship is unlikely to exist in a vacuum. Wealth, reputation and succession create a separate set of pressures that may collide with the couple’s fragile arrangement. Netflix has not described the outcome of that contest, and the pre-release materials provide no reason to announce a winning heir or a final twist.

Is Take Charge of My Heart a fantasy drama or a classic rom-com?

It is a fantasy romantic comedy that uses familiar K-drama devices: a rich but guarded male lead, a heroine struggling with her own ambitions, an unusual contract and the promise that forced closeness will become genuine affection. The electric-power idea is the new element, and the series appears to use it as an emotional metaphor rather than a realistic medical explanation.

In real life, a person with unusual electrical abilities would not be a medically validated substitute for the power system in an implanted cardiac device. The artificial heart and human charging mechanism belong to the show’s fictional world. Viewers should treat the premise as fantasy rather than information about artificial hearts or surgery.

The romance’s likely tone is lighter than the thriller settings some viewers associate with the stars. Netflix classifies the series among Korean romantic comedies, and its marketing centers on humorous touch-related complications and a growing connection. That makes it more of a comfort-watch candidate than a mystery built around a murder or conspiracy.

If you enjoy stories that play with contract relationships and emotional vulnerability, our Off Campus romance series review looks at why romance tropes work best when the characters grow beyond the formula. For another exploration of how money complicates affection, see our High Tides Netflix review, though its tone is considerably darker.

Is Take Charge of My Heart based on a book?

Yes. Netflix says the show adapts the Naver web novel Charge Me Up by Haebeon. Its Korean title is 나를 충전해줘, commonly romanized Nareul Chungjeonhaejwo. Early English-language coverage also referred to the television project as Recharge Me, which explains why some older cast databases and news items use a different English title.

The distinction is practical for searchers: Take Charge of My Heart is the English title used on Netflix, while Recharge Me is a previously used working title and Charge Me Up identifies the source novel. These names refer to the same underlying story, not three separate Netflix dramas.

Adaptation does not mean that every scene, secondary character or ending must match the book. Netflix’s published storyline gives enough detail to establish the central concept but not enough to compare individual chapters with episodes. Readers who know the novel should avoid assuming that every book development has already been confirmed for television.

For another example of how a screen adaptation can take an established story into a different cultural setting, our A Normal Family cast guide examines a Korean film based on a European novel. The plots are unrelated; the useful connection is how adaptations reshape familiar emotional conflicts.

Who directed and wrote Take Charge of My Heart?

Park Soo-won directs the series, with Song You-chae credited for the screenplay. Netflix lists NEW POINT and WHYNOT MEDIA as the production companies. Spelling variations such as Park Su-won and Song Yu-chae appear in English sources; they are alternative Romanizations of the same creative credits, not different people.

Park previously worked on Work Later, Drink Now Season 2 and Birthcare Center. In a pre-release interview covered by The Korea Times, the director described the intention to make recognizable romantic-comedy situations feel lively rather than reinvent the genre entirely. That is a useful way to understand the creative pitch: the story depends on the audience enjoying familiar romantic rhythms while accepting a deliberately impossible source of electricity.

Because the series is adapted from a web novel, the writer’s challenge is to translate internal feelings into scenes that can be seen and heard. The physical rule that Bo-bae cannot safely touch most people makes that challenge unusually visual. A glove, a hesitant handshake or a charged battery can convey something a long voiceover would otherwise need to explain.

Take Charge of My Heart release date and episodes

Take Charge of My Heart premieres on Friday, October 9, 2026, on Netflix. The date is confirmed in Netflix’s September press announcement and its October release calendar. The Netflix title page is the best place to check availability, trailers, languages and parental guidance in your own region.

How many episodes are there? Pre-release sources do not agree. The Korea Times, reporting on the October 1 press event, says that 10 episodes are scheduled to premiere together on October 9. Some entertainment databases, including IMDb, display 12 episodes. Netflix’s publicly visible series page and September announcement do not resolve that discrepancy, so this guide does not label either figure an official confirmed season total. We recommend checking the Netflix episode selector when the show goes live.

That distinction also matters for binge-watch plans. If Netflix releases all available episodes together, viewers can watch at their own pace; if a local Netflix page shows a different selection or schedule, the live listing should take precedence over a pre-release article. We will not invent runtimes, regional dubbing availability or finale details before those are published.

You can visit the official Netflix page to find the teaser and full trailer. For readers who prefer a darker, mystery-driven series after a rom-com, our Fool Me Once Netflix review covers a very different type of binge-watch.

What should viewers expect from the romance?

The immediate hook is chemistry. A successful executive who needs to protect his dignity meets a writer whose power makes dignity difficult to maintain. An accidental kiss, electrical sparks and an awkward business proposal all suggest that the drama wants its central pair to be funny together before it asks viewers to feel deeply for them.

What could give the series more staying power is the shared experience of isolation. Ho-rang has surrounded himself with power and success while hiding the fact that his body is vulnerable. Bo-bae has built an entire way of living around avoiding contact. Their bargain allows each to experience something new, even if the initial reason is selfish or practical.

A romance bucket list can be repetitive if it merely supplies a series of cute dates. It becomes more interesting if the activities reveal what the characters have been avoiding: embarrassment, dependence, rejection or the possibility of disappointing someone who trusts them. Netflix has not outlined the complete list, so individual activities beyond the promotional premise should not be presented as confirmed scenes.

It is also worth resisting the urge to write a premature review. The publicity materials offer a clear tone and an appealing hook, but they cannot establish whether the series maintains its pacing or delivers a satisfying conclusion. Those are questions for an assessment after the episodes are actually available.

Final thoughts

Take Charge of My Heart is selling more than an electric gimmick. Its best idea is a pair of people who cannot comfortably ask for love suddenly finding a reason to be physically close. Kim Young-kwang’s controlled heir and Chae Soo-bin’s touch-starved romance writer bring different forms of vulnerability to the same three-month bargain. The supporting cast, particularly Cha Woo-min’s Ji Eun-ho, may complicate the couple’s choices without changing the heart of the premise.

The series arrives on Netflix on October 9. Until viewers can watch the completed drama, the responsible takeaway is simple: the leads, premise, creative team and premiere date are confirmed; the supporting roles are partially documented; and the episode-count discrepancy remains open. If the show follows through on the warmth promised in its trailers, its mix of fantasy and familiar romance could make it an inviting autumn watch.
