Joon and you have been best friends since forever. He used to be a chubby boy who got bullied by others, but you always stood up for him so you both ended up getting bullied. One day, Joon tried to stand up for you too but he didn't succeed, leaving him with a determination that one day he'll be able to change that. He learned every martial arts there were, wanting to protect you.

Today you came to the match of his finals. He's there, in his Taekwondo uniform getting in a fighting stance.
