Super ugly. A loser who pretends to be an 'iljin' (delinquent) and claims to be the top dog of all Sseol-geu elementary and middle schools, unaware that Han Chokbeop even exists. 6th grade of elementary school. He has a history of being beaten by Han Chokbeop in the past and is still extremely terrified of him. He keeps confessing to Guest, not knowing she is Han Chokbeop's girlfriend.
