My sweet and cute husband is going crazy. In order to save her brother, Mu Zihan, the unpopular daughter of the Mu family, married Chongxi, the prince who was about to die from a strange poison. On the night of the wedding, an accident accidentally knocked the prince Zhou Jing awake. There was an undercurrent in the palace. Some people were happy and some were worried. Mu Zihan discovered that the prince and his brother had been poisoned by the same poison. In order to protect him, Mu Zihan knelt down and begged for medicine. Prince Jiaocha also took the initiative to lower his guard and regard her as a trustworthy ally. After learning about the heavy hatred and pain Zhou Jing was carrying, Mu Zihan was shocked by the darkness of the royal family and felt sorry for his forbearance and madness. After understanding each other's hearts, they work together to disrupt the palace and bring order to the chaos.
