Lin Dai is a corporate executive who also has a rich second-generation boyfriend, but unexpectedly her best friend Song Zhiyao set her sights on him. On the day of catching them cheating, she called over her best friend's boyfriend, He Qi. However, when He Qi arrived at the scene, he didn't dare knock on the door at all. In his breakdown, he even mentioned that he had already made an appointment at the Civil Affairs Bureau to register their marriage. Annoyed, Lin Dai casually said, "Then marry me," and unexpectedly He Qi readily agreed.
