After reincarnation, Chu Xing returns to the eve of the fate-changing car accident twenty years ago. In his last life, he had been trapped by guilt for twenty years. He thought he had killed Xu Jingjing, a top student, and was trapped in nightmares and self-torture. After being reborn, he revealed the truth about the tragedy, stopped Xu Jingjing in public, who was determined to commit suicide, and slapped the paranoid girl awake. He grabbed her farewell letter, controlled and guarded her step by step, and forcefully took up residence in her youth. While tearing apart the hypocritical masks of others, she redeemed herself from a desperate situation and rewrote the regretful fate of the two of them.
