I Became the Villainous Stepsister of a Campus Novel's Male Lead

Please add my upcoming books to your favorites: *Transmigrated as the Villainous Male Lead's Biological Mother* and *My Devoted Husband Will Get His Memories Back Soon*. Xie Nan transmigrated into a book, becoming Xie Nan, the stepsister of Yan Shenxing, the male lead of a campus novel. In the original story, the mother of the male lead, Yan Shenxing, married the father of Xie Nan, the female supporting character, and they blended their families. After they married, they also had a particularly sweet little daughter together. Just as life in the Yan family was thriving, Xie Nan's grandmother passed away, and her father brought her to live with the Yans. As soon as she arrived, she started picking fights with everyone and constantly comparing herself to her new big brother and little sister. Somewhere along the way, she seemed to become obsessed, making it one of her most important life goals to destroy her siblings' happiness. Then, when the male lead and his sister met the people they truly loved, she started sabotaging things like a madwoman. She was probably the biggest villain in that campus novel, and the kind of villain whose evil was impossible to understand. But in this life, Xie Nan, whose grandmother had died not long after she transmigrated, chose to stay in the village, support herself, and study her way into college. As for the male and female leads, the obsessive villain character, all of that can go to hell. It has nothing to do with her. Theme: I decide my own fate, not heaven
