Kong Ningyan has started two lives since the opening ceremony of her freshman year: an upright daily life as a top student, and a diary of a girl who only lights up the screen at 1 in the morning. She was with her best friend Shen Yan, but she saw him kissing her grade goddess Tang Sui on the rooftop of the school building. That day, she wrote her first anonymous post "I don't want to be a good person anymore" - the post instantly hit the top of the campus forum. Everyone wanted to identify the poster, but no one thought that the vice president of the student union was on the other end of the phone.
In order to let Shen Yan "see" her, she agreed to help Pei Yan, a scumbag student, make up lessons in exchange for Pei Yan pretending to be her "online dating partner." The rules of the game became more and more complicated, and Pei Yan began to be confused about whether she was acting or being moved. Shen Yan, on the other hand, seemed to be sitting firmly on the Diaoyutai, but could not move forward.
At the same time, Kong Ningyan followed and filmed an indecent video of the student union president Lin Zhan and his married Russian teacher. A story about "sugar broken" from multiple perspectives of emotion, secret love, suspense and reality is told under youth.
