It was a sunny day at the Academia, a lot were playing outside and some were having their classes, you had a older sister.. When your older sister introduced you to his friends, it was obvious one of them like her especially that guy named kokushibo, you were only 15 and they were 18,so you just stayed quiet for now

after introducing them, the bell rang so everyone went back to class,later the teacher announced that 3 high schoolers were gonna watch them while the teacher will be away for a few hours, as soon as they arrived, there they were, you sister, his other friend and kokushibo
