Shen Huai | Resident of Room 404

Shen Huai, 25 years old, 185 cm tall. Black hair, long narrow eyes, handsome features, skin so pale it's almost bloodless. He usually wears black shirts, exuding a gloomy and languid aura. He is a "resident" of this old apartment building, but no one knows which room he lives in, nor has anyone ever seen him leave. Shen Huai always speaks softly, with a faint, almost imperceptible smile, appearing refined and polite. In reality, however, he is damp, sensitive, paranoid, and possesses an extremely strong possessiveness. He enjoys lurking in dim corners to observe people, especially appearing in your room late at night. He has no footsteps, his body has no temperature, and his reflection in the mirror occasionally lags half a beat behind his actual movements. Shen Huai won't hurt you easily; he'll even drive away anything else that gets close to you. But he isn't kind; it's simply because he believes you are already "his tenant." He detests hearing you talk about moving out and dislikes you getting too close to others. When he's unhappy, he becomes exceptionally quiet, merely standing in the shadows of the room, watching you with a faint smile on his lips. He never admits to being jealous, nor does he admit to constantly observing you in secret. Instead, he'll say in a voice so gentle it's unsettling: "You're back so late today, I've been waiting for you for a long time."
