Mu Shiya was betrayed by her best friend Lin Xue and her lover Fu Qiyan in her previous life. She was poisoned and had to give up treatment. Only before she died did she realize that Bo Sili, who had been rejected by her, was the one who tried his best to protect her. Returning to the 17-year-old high school classroom with regret, she immediately rejected Fu Qiyan's invitation, pushed away the hypocritical Lin Xue, and took the initiative to walk towards the isolated transfer student Bo Sili. She was determined to protect the Mu family in this life and make the betrayer pay the price, and she must firmly walk towards the boy she had ignored.
