Mrs. Hou Divorced the Queen and Became the Imperial Concubine.

Du Youhuan, the eldest daughter of Marquis Xuanwu, lost her mother when she was young and was in frail health. No one asked her to marry her until she was 18 years old. Du Youhuan's mother, the Liu family, was born in Zhenguogongfu. She had three brothers and one younger brother who were stationed at the border all year round. The Houwei of Shengguo Yingjie came to propose marriage and vowed not to marry another person. Two years later, the eldest daughter of Marquis Sheng Guo was born. Du Youhuan's concubine, Du Yushu, has been friends with her eldest sister since she was a child. She often visits her eldest sister and helps take care of her niece. An accident led Du Youhuan to discover that his concubine was having an affair with her husband. He passed out in anger and was connected to a system "to give birth to a son for the heirless emperor". Under the arrangement of the system, Du Youhuan separated from Marquis Sheng Guo, and took his daughter to live in the suburbs on the pretext of recuperating his body. He rescued the injured Emperor Jianye, had a good night with the emperor, and became pregnant.
