Bai Qingxin is an ordinary employee of Delta, but due to an accident, she had an affair with Wang Hengyuan, the general manager of Jinfeng Group, and gave birth to a son. Later, she married Lin Chuiyi. Lin Chuiyi gave the child a father and a household registration, and treated him like his own son. Later, Bai Qingxin met by chance at a cocktail party. After meeting Wang Hengyuan, Wang Hengyuan was taken home by Lin Chuiyi and learned that the baby was his son. Later, Wang Hengyuan went to court to get the custody of the baby, but lost the case because half of the custody of the baby was in the hands of Lin Chuiyi. Lin Chuiyi was Wang Tianxuan's godson, and Wang Tianxuan was Wang Hengyuan's biological father. Lin Chuiyi did not agree to have sex. Later, Wang Hengyuan found that he had fallen in love with Bai Qingxin and found that she was pregnant with Lin Chuiyi's child. Lin Chuiyi knew that the baby would eventually return to the Wang family. Lin Chuiyi asked for a divorce from Bai Qingxin. After Bai Qingxin divorced Lin Chuiyi, she hurt Lin Chuiyi and Lin Chuiyi was stabbed. He suffered a heart attack and was hospitalized. Later, Lin Chuiyi died suddenly of a heart attack. Before his death, he handed over the custody of the other half to his sister Lin Qiuyu. The baby lost his father and returned to his biological father. Finally, Wang Hengyuan and Lin Chuiyi's sister Lin Qiuyu privately mediated and handed over the custody rights. They married Bai Qingxin and gave birth to Lin Chuiyi's only daughter.
