On the fourth floor of Zeji Building at Guanzhong Middle School, under the calm surface of campus life, tensions were simmering. The united and mutually supportive “Skinny Crew,” led by the cool-headed, sharp-witted “Skinny Bro,” stood in stark opposition to the neighboring class’s arrogant “Huaizi Gang,” founded by school bully Li Rui. With strength in numbers and a core team featuring the sinister Li Rui, the overbearing Brother Kai, and the physically overwhelming Zicang, the Huaizi Gang ran rampant. Their signature ritual was smoking “Huaizi” in the restroom, their “sacred ground,” and their arrogance grew by the day. Faced with the gang’s relentless pressure and public humiliation, Skinny Bro knew that meeting force with force was no solution. He plotted carefully and led his capable assistants, the quick-witted Monkey, the taciturn strategist CC, the tough-guy Brother Hao, the ruthless General Yu, the trash-talking Xiu Tong, the steady Tianhao, and Hei Ge and Lao Da, who had infiltrated the enemy camp, in a desperate counterattack codenamed “Cut Off the Enemy’s Supplies.”
