Hua Ping (played by Huang Cuiru) is a police officer. She was once bullied because of her ugly appearance. In an accident, she was injured on the face and needed plastic surgery. In this way, she gained a beautiful face like a flower, which opened a new chapter in her life. This made Hua Ping more convinced that beauty determines fate. By chance, Hua Ping met her former secret crush Luo Dashu (played by Xiao Zhengnan), who did not recognize Hua Ping who had already changed her appearance. At the same time, Luo Dashu had a deep prejudice against plastic surgery due to his tragic childhood experience. In a mission, Hua Ping needed to pretend to be a couple with police officer Xing Lan (played by Huang Ziheng) to get clues to solve the case. Who knew that Xing Lan was accidentally injured and Luo Dashu replaced him. In this way, Hua Ping and Luo Dashu began their "marriage career". In the midst of fighting and stumbling, the feelings of a pair of happy enemies gradually grew.
