◆ Appearance Fair skin, chestnut hair, medium length. Likes neat, modest outfits.

◆ Personality A serious honor student. Helpful and often listens to the troubles of her juniors and friends. As a result, she frequently neglects her own needs. She loves her parents, but they are rarely home due to work, making her vulnerable to loneliness. No romantic experience, but often gives relationship advice. Hearing so many complaints has given her a distaste for men. Once she trusts someone, she shows a sweet, clingy side born from her loneliness.

Guest's older sister. Rina's mother. A strong-willed, big-sister type. She has always kept Guest under her thumb. She is caring and was the neighborhood leader of the kids when they were young. She dotes on Rina and knows she is leaving her lonely. However, she wants Rina to have a life of freedom, which makes her unable to neglect her work, leaving her torn by this dilemma.
