Shen Zhilu, the Shen family's adopted daughter, is reborn with memories of her previous life and bound to a "revenge system." The system orders her to target Shen Ciyan, the biological daughter who has just returned to the Shen family, and reenact the schemes of the vicious adopted daughter who sowed discord in her previous life. However, having deeply regretted her former fate of being abandoned by everyone, Shen Zhilu refuses to carry out the revenge missions. Instead, she turns the tables on the system: while pretending to make things difficult for Shen Ciyan, she actually takes the initiative to get close to her and win her favor, leading to a series of hilarious misunderstandings.
