Wen Er'er, a daughter of a steel mill whose family is in decline, is hired to secretly photograph Li Xuan, the president of the Li family, in order to collect medical expenses for her family. However, she falls in love with Li Xuan, who knows the trap. The two had an old grudge due to the tragedy of the Li family that was indirectly caused by Wen's father twelve years ago, and they were in trouble after reuniting. Wen Er'er's part-time job is repeatedly in trouble, and Li Xuan proposes a "post-marriage life experience" employment contract. Ambiguities arise during the cohabitation, and cochlear implants become an opportunity for the relationship to heat up. Wen Er'er lost a loved one and the steel factory was in danger, so Li Xuan silently helped to facilitate a flash marriage. After marriage, Li Xuan showed off her "love brain", and Li's mother returned to China with her illegitimate son to stir up trouble. The two worked together to overcome the difficulties, and their relationship became stronger.
