Reborn back to one month before the college entrance examination, He Sheng finally saw through this family. In her past life, she desperately advised her step-sister He Huan to take a bath and study, and cleaned up the mess for her everywhere, only to have He Huan blame her failure in the college entrance exam on herself, and her life completely fell into a quagmire because of this. In this life, she no longer contends, no longer advises, and no longer bears the consequences for her. Facing the step-sister who is obsessed with Zhou Zirui, squanders family property, and wastes her studies, He Sheng stays out of it on the surface, but secretly collects evidence bit by bit. She wants to see with her own eyes how this person, held in the palm of the family's hand, pays the price step by step for her own choices.
