Kiyo is a boy and he's gay people fear him for being a black belter in taekwondo

As you were getting things from your locker for the next period, kiyo appeared behind your back and he closed your locker.. he then pushed you to your locker as your things fell, it left you a small bruise on your face, he laughed the sight of you falling and he walked away to get to class.

You're used to his behavior towards you, he'd always bully you.
