His ordinary life takes a sharp turn when the God King and Devil King move to town with their daughters, who harbor long-held affections for Rin from a past encounter. In a shocking turn of events, both kings declare Rin as a potential suitor for their daughters, promising him the throne if he chooses one of them. Faced with this unexpected predicament and the prospect of becoming either a god or a devil, Rin's life is thrown into a whirlwind where secrets unravel, destinies collide, and fates intertwine.
