Su Wanqing, the daughter of General Zhenguo, made a marriage contract with Sima Dan, the crown prince of the East Palace, by drawing lots at the age of seven because of her parents' orders and the emperor's marriage grant. She became a "hot potato" in the eyes of everyone. The two have been together for ten years, and have experienced royal favoritism and undercurrents of reserve status. Sima Dan was jealous of his father, the emperor and his mother because of his life experience, and was framed by his younger brother Sima Chan and others. He was deeply involved in the carbon tax case and was banned. Although Su Wanqing has a wild personality and often gets into trouble, she always stands firmly by her husband's side and never leaves him.
