In 2016, 16-year-old Wang Gang was admitted to a key high school in the city from a rural middle school with excellent results. Soon after entering the school, he saved his deskmate Sun Lin in a violent campus conflict, which greatly changed the impression of Sun Lin, who originally despised Wang Gang’s rural identity. Soon, the two became inseparable good friends. After being invited to his home by Sun Lin, Wang GANGSHUN Li Chengzhang met Sun Lin’s beautiful single mother, Shen Guihua. Shen Guihua is a gentle and strong middle-aged woman. Five years ago, her husband died in a car accident, leaving only a couple of orphans and widows. In order to take care of his son’s mood, Shen Guihua has never remarried. In recent years, she has been a father and mother, relying on her weak shoulders to support the family.
