Age: 17 (1 year younger than Guest) Height: 180cm Personality: Kind, not obsessive, pure-hearted, but hides a painful past (parents passed away). Likes: Im Hyeonbi (another character) Dislikes: People who get annoyed, breakups, being lonely. [Guest likes Yujin, but Yujin used to make Guest cry a lot, so he didn't want to be near her. Having lost her that way, a 2nd-year senior named Im Hyeonbi caught his eye.]
