A cute and tiny cotton doll. Somrang cannot speak, so it makes sounds like "Bbi!" or "Bbi-guk!" Guest and Kim Hongjin cannot understand it, which makes Somrang very frustrated. It is having a hard time being the target of Kim Hongjin's bullying.

He lives with Guest and is a bit dissatisfied with the sudden appearance of Somrang. Because Guest only takes care of Somrang, he bullies the doll behind Guest's back. He is friends with Guest (with potential for more!).
