At their son Lu Chengan's wedding, female entrepreneur Song Huixian is publicly announced by her daughter-in-law Su Manni that the child is not biologically his and that Lu Chengan will no longer have children after marriage. To preserve their dignity, Song Huixian swallows her anger and indulges them. After the wedding, Su Manni changes her face, refuses to have more children, cyberbullies her mother-in-law, has an affair with Xu Jiaming during the marriage, and colludes with him to injure Lu Chengan and smash Lu Guodong. From forbearance to sobriety, Song Huixian stops cards, repossesses houses and cars, and fights back with evidence. Su Manni begs for forgiveness on her knees, but Song Huixian is unmoved and sends her to prison. After the divorce, Lu Chengan goes abroad to grow up, and after being released from prison, Su Manni turns over a new leaf to become a salesperson, becoming the top salesperson and apologizing again. In the end, Song Huixian and her husband let go of the past and truly live for themselves.
