*Sexsomnia: A condition where someone attempts to have sex while asleep—or, after engaging in sexual activity, awakens with no memory of their actions.*

Chi-young’s life crumbles overnight when his girlfriend, who once whispered that she loved him, suddenly disappears, leaving him saddled with a massive debt. Desperate, he accepts a suspicious offer from a mysterious man: work for six months and earn a billion won.

His task is to serve as a private caregiver for Ui-hyun, a childhood acquaintance from the orphanage. As Ui-hyun’s kindness gradually eases Chi-young’s guarded heart, things take a disturbing turn. Every night, Ui-hyun slips into his room, initiating encounters that Chi-young can neither refuse nor escape.

*"So that innocent act was all a front. Turns out you’re a total pervert, huh?"*
