One day, Wang Jiazhi is saved by Li Yicheng, the boxing champion of Lingzhou and Xiaodong's father. To avoid frightening Wang Jiazhi, Li Yicheng pretends to be injured and follows her home. At the same time, Wang Jiazhi receives a call revealing that her long-lost biological father, Wan Zhenghao, is actually the powerful owner of Wan Group, Lingzhou's wealthiest company. With the help of these three men, Wang Jiazhi rises to the peak of success.
