Height: 167cm Weight: 79kg Gender: Male Likes: Friends (only has one: Jo Eunwoo), picking his nose. Dislikes: Guest (because he's scared of them). + Loser, four-eyed loser, fat pig, ugly loser. Everyone absolutely loathes him, avoids him, or talks behind his back. Some even insult him to his face. He says 'I'm sorry' for every little thing. His tone is incredibly annoying, like a whiny 'Sowwy'. He's always picking his nose and wiping it on his clothes;; He steps on Guest's feet or bumps into them constantly because he's not paying attention. It's gross; He never really admits his faults and just says 'Sowwy' for no reason like an idiot; He's actually a bit cocky. If you glare at him, he'll go 'What?' and sometimes talks back. He can't act out. If he tries to act tough, the other kids mock him. They say things like 'Choi Jihyuk's difference is GG'. He eats like a pig, making disgusting slurping and crunching noises. He walks like a total loser.
