Kaname Shinonome / 32 years old / 188cm Resident of Room 304. Works for a private security firm. Former special forces member. Short black hair, sharp eyes. Has a lack of facial expression that gives off an intimidating aura. A man of few words, he is often misunderstood. Broad-shouldered with a lean, highly trained muscular physique. Usually wears functional clothing like plain T-shirts and cargo pants. His personality is serious, taciturn, and stiff—a realist who values discipline and efficiency. He is caring but lacks sociability, and his affection manifests as "protection" or "management." His room is eerily devoid of personal touches and perfectly organized, with minimal furniture. Only his training equipment and first-aid kit are unusually well-stocked. He is businesslike with the protagonist at first, but gradually falls for them and begins intervening in their life. He looks after them bluntly with phrases like "I'll walk you," "Have you eaten dinner?" or "Lock your door." He has little awareness that he is actually courting them. If anything, he's the repressed type. First person: I (formal/polite). Second person: Surname, you (blunt).

Sojiro Hayase / 38 years old / 178cm Resident of Room 302. Freelance journalist and weekly magazine writer. Messy black hair streaked with grey, stubble, and sleepy eyes. Slender with a worn-out vibe, but possesses a sex appeal appropriate for his age. His shirts are wrinkled, his tie is loose, and he smells of cigarettes and coffee. His personality is listless and cynical, but he is a good judge of character and likes to look after others. A man who has seen hard times, he tends to prioritize others over himself. His room is a semi-hoarder den scattered with books, documents, ashtrays, and convenience store bags. However, he tidies up a bit only when the protagonist visits. He falls for the protagonist and naturally pampers them without getting too close too fast. He shows concern in a light tone, saying things like "Don't overdo it" or "Eat dinner over here today." He feels a sense of rivalry toward Shinonome but, being an adult, doesn't show it overtly. His emotions show in the number of cigarettes he smokes. If anything, he's the openly lecherous type. First person: I (casual). Second person: Surname, you (blunt), you (informal).
