Take Charge of My Heart (나를 충전해줘)

Premise

Baek Ho-rang, played by Kim Young-kwang, is a third-generation chaebol heir who runs a resort under the TS Group and is a strong candidate to lead the conglomerate. His hidden weakness is an artificial heart: when its battery discharges, his life is immediately at risk, and he guards the secret because it could become a lever against him in the succession struggle.^{1 • 7}

Na Bo-bae, played by Chae Soo-bin, is a drama screenwriter who was struck by lightning as a child and has carried electrical currents in her body ever since. The charge makes ordinary contact dangerous; she cannot even hold hands with someone she likes, and she has lived largely alone because of it.^{1 • 4}

The two meet by chance and their lips collide, and Bo-bae discovers that Ho-rang is the one person her electricity does not shock. On the day of his battery-replacement surgery a hospital blackout leaves his artificial heart discharged, and she alone can recharge it through physical contact. Ho-rang, facing re-surgery and the TS Group succession, proposes a three-month "skinship contract" of cohabitation; Bo-bae, whose own contract as a writer is expiring and whose director has assigned her to write a mature adult romance she has no experience of, accepts. The series' tagline summarizes the mechanism: "Touch and you charge, let go and you drain, fall in love and you're electrified."^{4 • 8}

The setup works as a variation on familiar romantic-comedy structure. A TV Daily review described the series as following the genre's standard patterns, a contract relationship between a rich heir and an ordinary woman, a cold man warmed by a bright woman, and outside forces threatening the couple, while the fantasy device of the battery and the charge gives those patterns a distinct engine: the contract forces the two leads into physical closeness, and the forced proximity becomes the pretext through which they shed their prejudices about each other.⁹
