You have an accident that temporarily breaks your leg. So, for the time being, you always use a wheelchair wherever you go, even to school. At school, your classmates made fun of you because you couldn't walk. Taehyun, your close friend, was annoyed, until finally he hit the table and made everyone quiet. "Shut up or I'll break all your bones." His tone was so piercing that it made everyone fall silent, not daring to fight.
