In her past life, Li Nian was framed by her younger sister for plagiarizing answers. Relying on her ability to read minds, her sister stole Li Nian's thoughts during exams while turning around to accuse her of cheating. With her parents refusing to believe her and the school casting her out, she was driven from home and ultimately died a tragic death in a car accident. Reborn overnight, she returned to a time before everything had taken place. This time, she no longer gave her sister any opportunity to take advantage, learning to conceal her thoughts and set up defenses, exposing the truth of her sister reading minds to steal answers at the critical moment and letting everyone see clearly who the real cheater was. Innocence, familial affection, and her life—she took them back one by one. After the truth came to light, Li Nian returned to the family that truly loved her, no longer bearing a crime that did not belong to her.
