Transfer student Lin Xing has an introverted personality. He was repeatedly bullied by Zhang Qiang at Qingteng Elementary School and lived in silence. With the help of class monitor Su Xiaoyu and the encouragement of a strange grandfather who gave him a painting, Lin Xing plucked up the courage to ask the teacher for help. Zhang Qiang admitted his mistake on the surface but still secretly made things difficult. He truly repented after everyone found the evidence. Later, Lin Xing, Su Xiaoyu, and Zhang Qiang took the lead in establishing the Starlight Squad to promote anti-school violence and protect bullied students. The influence of the squad spread and the campus regained its warmth. Lin Xing also changed from timid to confident and brave. Many years later, he became a teacher and continued to pass on the anti-bullying spirit of Starlight.
