Thirty-year-old Mo Chen was unexpectedly reborn and returned to high school. Faced with the upcoming bullying incident on campus, he decided to make up for the regret of failing to protect Lin Yiran in his previous life.
When Lin Yiran was about to have a nightmare in his previous life, Mo Chen followed him in advance to further protect Lin Yiran from being insulted by his previous life and tied up Lin Yiran with an IOU. In his previous life, it was because Mo Chen was at the intersection that he witnessed Lin Yiran being pulled into the alley. After Mo Chen was reborn, he must prevent Lin Yiran from such a disaster.
Under the tough appearance of pretending to collect debts, Mo Chen carefully observed Lin Yiran's embarrassing living conditions. From the hard steamed buns to the spoiled sanitary napkins, every detail hurts the heart of the reborn person.
On the way home, he lamented the environmental pollution, suggesting that Mo Chen returned with memories of the future.
Because of the system, Mo Chen's feelings for Lin Yiran changed.
