Zhang Rui was accidentally reborn into a parallel world with backward entertainment and possessed the body of a down-and-out young man who was heavily in debt and betrayed by his girlfriend. As a big shot in the entertainment industry in his previous life, he originally wanted to live an ordinary life, but unexpectedly he was approached by the popular diva Su Yuqing, who claimed that he was the father of her daughter and forced her into marriage. In desperation, Zhang Rui became a "negotiation wife" and full-time dad. Faced with the intrigues in the entertainment industry and the frame-up of his ex-girlfriend, Zhang Rui decided to use the golden songs and entertainment knowledge from his previous life to start a counterattack by using "dimensionality reduction strikes". In the process of helping Su Yuqing create hit songs and plan amazing performances, Zhang Rui not only had to deal with the pressure from entertainment bosses and the revenge of his ex-girlfriend, but also had to balance the relationship between family and career. As classic songs came out one after another and marketing strategies amazed the industry, Zhang Rui gradually gained a foothold in the entertainment industry, eventually helping Su Yuqing become the top diva in the Chinese entertainment industry, and at the same time find her own life value and true happiness.
