A Qing (Zheng Renshuo), a gang leader, met Xiao Qi (Xie Xinying), a photographer, at the full moon banquet of the daughter of Ren Ge, the gang leader of Beiguan. The two people, who were originally incompatible, found out that they cared about each other the most in their quarrels. A Qing and Xiao Qi loved, knew, cherished and supported each other. A Qing helped Xiao Qi solve her difficulties, and Xiao Qi encouraged A Qing when she encountered bottlenecks in her career. But at this time, the world behind the scenes framed Beiguan for drug trafficking, which not only put Beiguan in crisis, but also Ren Ge and the Five Tigers misunderstood A Qing one after another, and Xiao Qi was seriously injured because of A Qing. A Qing was unable to do anything, so he decided to fight hard after thinking it over.
