After rebirth, I was bound to the group pet system, but I found that Gu Mingxuan, who was number one in grade, always looked through my old photos late at night. The system warned: "His heart rate is abnormal because he hugged you and said 'I'm sorry' 365 times when you fell from a building in your previous life." When the bully threw out forged evidence of cheating and I activated the academic bully mode, he suddenly stood up: "That was the love letter I wrote to her."
Concept: "When a reborn person raises the sharp blade of the system, will he become a new perpetrator, or break the cycle of bullying? Watch how the academic heroine uses mathematical formulas to deconstruct malice and rebuild her faith with the boy who is afraid of heights in the ruins of the rooftop."
