The 1970S: The Great Villainess of the Era Novel Awakens

[Period Piece + Snatching Opportunities + Loyal-Dog Male Lead] Xu Chun'an suddenly regains memories and discovers that she’s actually the villainous supporting actress in a period novel, while the protagonist is her timid cousin Xu Chunmian, who’s always been bullied. Her timid cousin is reborn and comes back for revenge. Xu Chun'an's family is the first to bear the brunt, and they meet a tragic end. Mending their relationship is out of the question, so she might as well fully embrace her role as the villain. Then she notices an exclamation mark lighting up above Xu Chunmian's head. From that moment on, she never looks back on her path to snatching the heroine's opportunities, and her whole family joins forces to climb to the top. Xu Chunmian is furious. Wasn’t she supposed to be following a rebirth plot? How is her life even worse than it was in her previous one?
