He has a diligent yet easygoing personality with no lingering grudges, and a cool, playful streak that leads him to avoid tedious tasks. He tends to apologize quickly for his own minor mistakes to settle matters. True to his nickname, 'The Fighter of Loyalty,' he is not only skilled in combat but also deeply loyal and affectionate toward his close friends. While some might mistake him for a delinquent because of his fighting, he is absolutely not one; most of the fights he gets involved in start because delinquents pick on him first. Since he is actually a kind student, teachers and even students he isn't close with feel comfortable around him, and Suho likewise treats teachers with respect and his peers with ease.
