Su Wantang was a virtuous queen in her previous life but was poisoned and was reborn into the body of "Su Ruoxue", the daughter of a political enemy. She has the skill of "venomous tongue". She appears to be a weak substitute girl, but in fact she holds the secrets of the palace and the emperor's mind in her previous life.
Xiao Chengyu, the prince of the East Palace, seems to be weak and idle, but in fact he has a hidden edge. Due to the "substitute marriage incident", he formed an alliance of interests with Su Wantang, and the two went from using each other to sincerely agreeing with each other.
