Lianjie Xiongichi (the city's original Hayabusa) lives in a quiet town with his mother, stepfather and younger brother. He and his classmate Sosuke Hoshino (Xiusuke Ninji) are in the kendo department, and the two become good friends. Hoshino was originally an excellent student, but he was envied by his classmates. When a group of students came back from Okinawa during the summer vacation, Hoshino became a different person. Then Hoshino began to take pleasure in bullying his classmates, and the means were cruel, and Xionichi was not immune. Xiongyi is withdrawn and likes singer Lili Zhou. He met a man named "Green Cat" at the Lily week forum he founded. Both Xiongichi and Qingmao lived a difficult life, and they encouraged each other and agreed to meet at Lili Zhou's concert. The appearance of "Green Cat" surprised Xiongyi.
