When he was thirty, Zhong Shijie (played by Zheng Zhongji) was a cynical and unrestrained playboy who helped his father run a large chain of bridal shops. He attached great importance to efficiency and hoped to handle everything within three minutes. During a wedding dress show held by the company, a child, Yongyan, suddenly recognized him and called him dad. Because Zhong Shijie's girlfriends were like a revolving lantern, he had no impression of the child's mother at all, and Zhong Shijie even suspected that this was a scam. Later, after testing, it was found that Yongyan's mother had passed away for many years, and Yongyan was taken care of by his aunt Caiyu (played by Ying Caier). Caiyu is a Chinese medicine doctor who loves Yongyan very much. However, due to the economic downturn in recent years, the burden of taking care of Yongyan has become heavier and heavier. In addition, her sister hopes that Yongyan can meet the father and son reunion, so Caiyu decided to let Yongyan recognize Shijie. Shijie always suspected his relationship with Yongyan and secretly tested his DNA with Yongyan. Before the result was obtained, Shijie had to muddle through.
