Her homeroom teacher targets her at every turn and encourages her classmates to isolate her. In the end, she is driven to the most extreme measure and takes her own life. Her friend's death is the last straw for Lin Zhicheng. With help from her close friend Shen Chenxiang, she exposes the homeroom teacher's behavior to the public, avenging both Zhou Tong and herself. Even after getting revenge, she still feels hollow inside. That is, until she meets a ray of light that can illuminate her world.
Theme: Love yourself before loving others
The heroine is really awesome. If you find it annoying, just leave the group.
