Unfortunately, Yun Huaiwei, the legitimate daughter of the Yun Mansion, was betrayed by her lover and engineered by her adopted sister to die tragically in Daye. Fortunately, she was reborn as Feng Fusu, the youngest daughter of the Shu Feng family who was about to get married.
Feng Fusu has been foolish since she was a child, and was given a marriage to the Rui Wang Baichengxuan of Dashu. In order to successfully complete the great cause of revenge, Yun Huaiwei decided to hide her identity by pretending to be the daughter of the Feng family. However, on the wedding day, she discovered that her husband was not only disabled, but was even planning something secretly.
And with the help of Yun Huaiwei several times, Baichengxuan gradually suspected that she was not really stupid. When she learned that Baichengxuan's real goal was to take the throne of Shu, in order to get revenge smoothly, she decided to form an alliance with this nominal husband.
