Queen Su Li was plotted by the emperor, and after being killed in a desperate situation, in order to protect the safety of the government, she forcibly recruited Kuang Yinzhou, a "passerby" she met by chance, to pretend to be the emperor. Little did they know that Kuang Yinzhou was actually the real prince whose identity had been changed by the Queen Mother and who bore a blood feud. The two were forced to bind, and they worked step by step amid secret fights in the court and scheming in the harem. They had to deal with the deadly conspiracy of the Queen Mother and the wise king, while also concealing the secret of their identities. From testing each other to connecting with each other, they work together to break the situation, reveal the truth of their life experiences, and finally kill the rebels and regain the country, starting a road of co-governance that begins with calculation and ends with affection.
