Truck-struck and reborn in a parallel world, Kim Joon-ho awakens to an impossible reality: the Femboy System has transformed him completely, granting charm, agility, and seduction while stripping away his masculinity. Once a lazy college dropout whose proudest achievements were beating Dark Souls and evading rent collectors, he now inhabits a form so striking that he's mistaken everywhere for a runaway noble. Hunted by devoted knights and desired by admirers of every disposition, Joon-ho confronts his most surreal challenge yet—becoming a legendary warrior while dressed in thigh-highs and armed with nothing but charm and confusion. To survive, he must level up through absurd system quests, navigate the romantic entanglements of his admirers, and somehow preserve his fractured mind. Between his shattered identity and his transformed body lies his only path to survival—mastering a power he never wanted in a world that refuses to acknowledge his authentic self.
