In order to make up for his debt, Xie Bian, the ace seductress of the underworld, took a leave of absence and came to the modern city where spiritual energy was revived to become a full-time nanny. He hides his identity, uses the methods of the King of Hell to resolve conflicts among parents, purifies evil spirits in the community, and runs an agency that specializes in "special business." Until one day, the five-year-old daughter pointed at the new transfer student in the kindergarten and said, "Dad, there is a black aunt lying on his back." Xie Bi'an sighed helplessly and took out his mobile phone: "Old Zhong, help me check the birth and death book, and by the way... Ask for parental leave." Since then, there has been a living Yama with a baby in urban legends, and a super cute baby who can turn a hundred ghosts' night walk into a parent-child amusement park.
