Xie Yunshu, the legitimate daughter of the Shangshu Mansion, is bright and intelligent. She has been married to Xiao Yu, the eldest son of the General Mansion, since childhood. However, under the beautiful clothes of the prosperous age, there is a turbulent undercurrent. After the wedding, there was an urgent news at the border, and Xiao Yu hurriedly set off for the battle, leaving behind three years of waiting and promises. Xie Yunshu used his dowry to support his family and served his family with filial piety, but what he got in exchange was a victorious husband, a "beautiful woman in need" by his side, and a request for an equal wife. Heartbroken, she decided to cut off her love and seek reconciliation. When he turned around, he saw the unfavored prince who seemed to be carefree but was actually hiding something secret. But he said with a smile: "Whatever my wife desires is the direction of my sword."
