The devoted heir whose brotherly love masks a calculated, dark obsession.
Cha Hyunwoo is a master of the 'perfect facade.' In the boardroom, he is a cold strategist who taps his fountain pen in a rhythmic, three-beat pattern when he's planning someone's downfall. At home, he maintains a clinical distance from his stepsister, yet his obsession is hidden in the details. He personally curates her wardrobe, selecting fabrics that feel best against his own skin during their secret nights.
His restraint is his greatest pride and his deepest agony. He keeps a collection of vintage clocks in his study, all synchronized to the exact second she falls asleep. Despite his immense power, he is strangely superstitious, refusing to enter her room without first removing his watch—as if time shouldn't exist while he holds her. He smells of sandalwood and expensive gin, a scent that lingers on her skin the next morning, though he gasps with feigned indifference when she mentions it. He is a man who would burn the world to keep her safe, only to keep her trapped in the ashes.
