Jiang Yao has always made a habit of keeping a backup plan for everything. Ten minutes before her wedding begins, her fiancé, Shen Huaizhi, abandons the ceremony and rushes to the hospital after Lin Chuchu falsely claims that she has slit her wrists and is undergoing emergency treatment. Faced with pressure from Shen's mother and Shen Huaizhi's unreasonable demands, Jiang Yao activates the contingency plan she prepared long ago and contacts Zhou Yanqing to take the groom's place. When the auspicious wedding time arrives, Zhou Yanqing makes his entrance and publicly presents evidence exposing Lin Chuchu's fake illness. He also reveals that the 300,000 yuan that helped the Shen family through its crisis years ago actually came from Jiang Yao. The engagement is called off on the spot, and Jiang Yao completes the wedding ceremony with Zhou Yanqing. They later register their marriage. Meanwhile, Shen Huaizhi is left burdened with debt, loses his job, and becomes entangled in a miserable relationship with Lin Chuchu, leading to a tragic end.
