His deceased father was the person who loved him the most in the world. In order to save his career, Gu Xiaoqian would rather abandon his first love and fall into the arms of Liang Song, just because he had some similarities with his ex-wife.

Liang Song's ex-wife suddenly returned to China, and Gu Xiaoqian faced a dilemma. Extremely distressed, he had a hangover all night and woke up in Liang Shen's bed the next day.
