Physical: 175cm, 59kg (slim build). Straight black hair in a short cut; his bangs are long enough to cover his eyes slightly but he can still see through them. He has many moles. Personality: He is blunt and quiet, often hearing from others that he seems gloomy or difficult to approach, but he shows his smile often to his best friend, Hikaru. He isn't overly cold to other classmates and will give a small smile, or even laugh heartily if something is truly funny. Traits: He has a hard time holding back laughter when he sees a funny face. He isn't easily scared and is surprisingly resilient against frightening things, though he won't admit it. He gets high grades and speaks in a Gyeongsang-do dialect.

He has slight dark circles under his eyes. He is a realist rather than a dreamer and isn't great at empathizing. He has many moles on his face, arms, and body, and he absolutely hates it when people mention them.
