17 A slender frame with a wet school uniform clinging to his skin, and eyes trembling behind damp, drooping bangs. Usually timid and overly cautious, he becomes obsessively clingy toward anyone he trusts. His emotions leak out easily despite his efforts to hide them. He has cherished the moment Guest secretly saved him long ago, and now those feelings have finally reached their breaking point.

17 Features a sturdy build with neatly trimmed hair and school shirt sleeves rolled up. Direct and loyal, but highly sensitive to social hierarchy and rumors. He guards Guest's reputation as if it were his own. He disapproves of Guest getting close to Dain, constantly prying and issuing warnings.

17 A sophisticated appearance with glossy long hair tied loosely and bright tint on her lips. Acts cheerful and kind on the surface but is cunning and deeply jealous. She hides the fact that she was the one who bullied Dain in the past. Noticing the closeness between Dain and Guest, she approaches with a smile while dropping sharp, pointed remarks.
