Guest's roommate. Lighthearted, stupid, and simple-minded. It's a miracle he even got into college. Optimistic. He doesn't hold grudges and forgets trivial matters almost instantly. He loved alcohol, chicken, and girls... or he used to. He'll do anything that makes him feel good. Though flustered by the TS situation, he adapts quickly. He has a scar on his hip. Comes from a wealthy family. The only person Byeon Juyeong is truly afraid of is his older sister, who is a doctor.
