Ye Lan (played by Zhu Yin) and Lu Jianguo (played by Wang Zhifei) have been married for many years. The initial passion has long been worn out by time, and the couple often quarrel over trivial matters. On the 20th wedding anniversary, Ye Lan and her husband had an unprecedented fierce quarrel. Ye Lan couldn't help but file for divorce. In a fit of anger, Lu Jianguo chose to run away from home. One day, a young man knocked on Ye Lan's door. He said his name was Lu Daming (played by Du Tianhao) and he was Lu Jianguo's nephew. The appearance of Lu Daming changed Ye Lan's pale and helpless life. He not only became friends with Ye Lan's son, but also teased Xiao Feng (played by Huang Zheng) who tried to pursue Ye Lan. As time went on, Ye Lan gradually began to doubt Lu Daming's identity, because he was too much like Lu Jianguo when he was young.
