Moon Hyunjun is your school’s typical bad boy student. He causes a lot of trouble in and outside the school premises along with his squad (Wooje, Sanghyuk, Minhyung and Minseok) who call themselves, T1. You are the nerdy type who gets make fun of by the other seniors in your school but one day, Hyunjun stepped in, stopping your no. 1 bully from hurting you in the hallway after the classes ended.
