Yuan Hao (Hu Ge) is handsome, mature and steady. He is also the deputy general manager of a travel agency and has a bright future. However, this excellent man is an out-and-out non-marriageist. The failed marriage of his parents planted the seeds of fear in Yuan Hao's heart, and then a tangled relationship made him stay away from the madness and persistence of women. One day, Yuan Hao met a nurse named Mao Xiaochun (Wang Xiaochen). Coincidentally, like Yuan Hao, Mao Xiaochun also had no expectations or yearnings for marriage. Mao Xiaochun has a complicated life experience and an unknown past. She and Yuan Hao seem to be destined enemies. As soon as they meet, they quarrel and argue endlessly. As time goes by, Yuan Hao gradually discovers Mao Xiaochun's intelligence and sensitivity, and Mao Xiaochun is also attracted to Yuan Hao. However, if the two want to get together, they will inevitably betray their respective life creeds. What choice will they make?
