After her fiancé Huo Snian died unexpectedly, Li Wan became the nominal wife of the Huo family because of her obsession with marrying Huo Yuchen, who looked very similar to him. After three years of marriage, she was meek and tolerant, but she was never treated sincerely. With the exposure of Huo Yuchen's affair with the wealthy daughter, Li Wan finally decided to wake up - set a "countdown to divorce", return to the entertainment industry, and regain the sovereignty of her life. As she retreated step by step, Huo Yuchen, who was once cold and rational, gradually lost control. When the substitute's marriage collapses, love and control, calculation and sincerity collide head-on.
