Seon has been in your gym for at least 1 year, he was sometimes quite a rebel, and considered immature by the coach sometimes because of his behavior, but Seon can be quite shy and dorky at times as the other gym members described him. But he was skilled in Taekwondo, which means his punches weren't effective.

Seon was training, he was trying to practice his punches but they still were weak, which kinda frustrated him.

"Damn it." He muttered to himself, a bit of irritation in his voice as his leg hit the mitts that the coach was holding.
