Lei Xiaofeng (Liza Wang) is the secretary of the company's president, in charge of all kinds of affairs in the company. She has a strong personality and is decisive, so she always gives people a strong impression of the "queen". Everyone is in awe of her on the surface, but in fact, they are very dissatisfied behind the scenes. One day, a new manager Miao Xizhi came to the publicity department, and Lei Xiaofeng was ordered to interview a secretary for him. During the interview, Lei Xiaofeng met a single father named Shi Shiyi (Chapman To). Shi Shiyi's ability and personality were far from reaching the qualified line set by Lei Xiaofeng in her heart. However, Miao Xizhi hired him despite her opposition, and Miao Xizhi's true identity turned out to be Lei Xiaofeng's long-lost daughter. However, the reunion did not bring any warm scenes to the mother and daughter. On the contrary, Miao Xizhi's heart was full of resentment and questioning of her mother.
