According to rumors at Nanjia High School, Qi Bei, the school's notorious troublemaker, was born bad: rebellious, cold, and ruthless. They say a single kiss from him is worth a fortune, and everyone can only admire him from afar, afraid to provoke him. While others fear his unpredictable and vicious nature, Jiang Nan, who suffers from bipolar disorder, thinks nothing of him and sees straight through his deliberately constructed tough exterior. Two equally sharp-edged individuals cross paths, confronting each other without backing down. Amid the push and pull between a strong-willed boy and an equally formidable girl, these two scarred teenagers gradually break through each other's tough armor. In the noisy world of their school, they embark on a bumpy journey of mutual salvation.
