Gu Xingchen, the number one student in No. 8 Middle School, looks gentle and beautiful, but actually has a rough fate. He has seen too much ugliness, and his heart is pessimistic and self-closing. Fate closed all his doors, leaving only one window: that arrogant girl, Xu Yu. She has a lot of friends and is always surrounded by crowds, smiling and having endless fun. Gu Xingshen seems to be an insignificant existence in her world. But for Gu Xingshen, Xu Yu is the one who lives on. The only belief. Her sunshine, cheerfulness, and enthusiasm flowed into his cold and numb heart like blood.
