She Came From the Back Door of the Brothel

In her past life, the legitimate daughter Xu Yue gave everything to the Xu family, only to be pushed by her biological father Xu Cang and brother Xu Shuyue to take a fatal stab for the concubine's daughter Xu Qingyao. After rebirth, she discovers her father and brother have also returned, only to be dumped into a brothel where she is rescued by the lost prince Chen Yuanan. Over sixteen years of companionship, upon returning to the capital, Xu Yue strategically dismantles Xu Qingyao, exposes Xu Shuyue's academic fraud, and sets up the Xu family to lose everything, all while helping Chen Yuanan reclaim his lineage and ascend to the position of Crown Prince. Facing a conspiracy by the Xu family, the Empress Dowager, and Prince Jing'an, the couple breaks the deadlock together. Ultimately, Chen Yuanan ascends the throne as Emperor, Xu Yue becomes the Empress, and they jointly create a prosperous era, with all past grievances finally dissipated.
