Shen Xueyi (Guo Keying) ignored her father's opposition when she was a second-year university student, and suspended school to marry a wealthy son. In the early days of marriage, Yi thought she was a princess living in a castle in a fairy tale until she broke her husband and had an affair. The castle was originally made of sand, and the waves collapsed immediately: Yi suffered from postpartum depression, divorced her husband, and lost her son's custody. Fortunately, Ye Xianghui (Ou Jintang), a friend, supported Yi Yiru into a lawyer's office as a master.
