An accident made Mingliang (Qi Wei) and Gao Jian (Chen He) become good friends and confidants who didn't know each other. The two people who have the same view of love and marriage hit it off and became "one-night lovers" who warm each other. As time goes by, the increasingly intense feelings between the two are about to get out of control. At this juncture, can they abandon the old principles and bravely come together? Bao Niannian (Mao Xiaotong)'s unexpected pregnancy made her and Wan Siqi (Wang Chuanjun) decide to get married. However, on the day of getting the certificate, Bao Niannian's unfortunate miscarriage immediately made this marriage a dispensable chicken rib. Yu Xiaonuo (Jiang Yan) suffered from her boyfriend Cheng Lei (Qiao Renliang) having no money and power, and decided to find a tall, rich and handsome man to "abandon the dark and join the light". But at this time, Cheng Lei became famous overnight, but the relationship between him and Yu Xiaonuo could never go back to the past.
