28-Year-old Lin Xiaolu died suddenly and was reborn on the first day of his senior year of high school. He decided to make up for the regrets of his previous life by bravely approaching the school bully Shen Mo, who he had a crush on for ten years. However, she soon discovered that Shen Mo in this life was full of doubts: the bruise on his left wrist matched the scar from the car accident in his previous life, his mobile phone showed the future date, and the way he looked at her seemed to have already understood the secret of her rebirth.
When the "life restart system" in Lin Xiaolu's mind assigned a task, when she discovered the strange time symbols in Shen Mo's notebook, and when she touched the hearing aid that left him deaf, a terrible truth gradually emerged: this rebirth was not an accident, but a carefully designed experiment. Who is Shen Mo? What kind of life and death choice is hidden behind his words "don't make the wrong choice this time"?
