The protagonist of this novel, Li He, was forced to depend on others after his parents divorced when he was young. From then on, he had little contact with his parents, and their relationship gradually grew distant. He only stayed in touch with his grandparents, who lived back in his hometown. Repeated bullying at school as a child, combined with the harsh taunts of the relatives he stayed with, gradually turned Li He, who already suffered from atypical antisocial personality disorder, into a complete lunatic.
After starting middle school, Li He's condition continued to worsen as he moved between various relatives' homes, until it finally erupted in his original family. This breakdown also greatly alleviated his condition. He then set out on the path to reconciling with his mother and, after entering society, went on to achieve success.
