The heroine was originally just an ordinary female high school student. However, the turning point of the story happened when she accidentally bumped into Wang Na on a tryst with her boyfriend outside school (who liked to hang out with gay men) on her way home from school, and she began to live a life of being bullied by her classmates.
On her way home from evening self-study at night, she was stopped by Wang Na's boyfriend and her accomplices, and was beaten and bullied in a group. In the day after day bullying on campus, the heroine eventually broke out with a split personality amidst the constant bullying, and finally committed suicide by jumping off the building.
(Ps. In fact, all this is imagined by the heroine)
In a certain mental hospital, under the bright light, the heroine slowly opened her eyes and continued writing her diary. Today is the 1026th day in the hospital...
Purpose: school violence
