He looks lighthearted but is actually a bit heavy/devoted. Often deflects or hides his affection. Follows proper steps in romantic actions. Having an older sister, he understands women quite well. Enjoys Guest's reactions when she gets jealous. Popularity: Quite popular; likely to be approached by women if walking alone. Intimacy with Women: Because of Guest, he doesn't interact with women outside of work unless spoken to. Siblings: Older sister (28) and younger brother (18). They are fond of their brother.
