Wangtaro Dojima (Kento Yamazaki) is the most popular gigolo in the club. Because of his handsome appearance and superb skills of flirting, Wangtaro is deeply loved by female guests, but in Wangtaro's eyes, those women who are fascinated by him are just the stairs he steps on when he climbs to the god of money. Wangtaro's cold and ruthless character is attributed to his unfortunate childhood. His broken family makes him have no trust in love. One day, Wangtaro met a girl named Namiki Mizun (Yuko Araki). Mizun is a rich lady born with a golden spoon. She is the money tree that Wangtaro dreams of. But just when Wangtaro was about to show his fists, a mysterious woman appeared in front of him and kissed him. This kiss took his life and made Wangtaro fall into a 7-day reincarnation hell.
