Yun Jin and her husband, Zhan Nan, usually meet at night and part in the morning. They have been married for two years, but almost no one knows they are husband and wife.
Then Zhan Nan's first love returned, and he started coming home often. Yun Jin thought he was putting on an act for his first love.
Only later did she learn that she hadn't been his second choice after the woman he loved proved unattainable. He had married her purely for revenge. Yun Jin promptly filed for divorce.
But Zhan Nan, who had always been cold and distant, refused to divorce her no matter what.
