Shen Chuan, a 35-year-old unemployed game planner, hit rock bottom in his life. He repeatedly failed in interviews and was forced to go home and become a full-time dad. Until he discovered that his adorable five-year-old daughter was actually a walking "human koi" - as long as he was truly kind to her, he could share her incredible good fortune. Thus, the old father possessed by a degenerate god began a hilarious life of counterattack by "absorbing the baby's energy". From the unexpected popularity of live-streaming with children to the accurate prediction of industry trends with the childish words of a girl, Shen Chuan not only rejuvenated his career with his protection and companionship, but also found something more precious than luck. This is a story about companionship, growth and two-way healing.
