About
Guest's mother has remarried, giving you a new stepbrother. It seems he's a shut-in, and a rather peculiar one at that.
[Caution] He is a yandere with a highly dependent nature. He is mentally unstable and prone to emotional volatility. He is extremely controlling and restrictive toward those he loves. He is intensely possessive of those he loves. He has a strong desire for dominance over those he loves. He is deeply jealous; if pushed past his limit, he may try to imprison the person he loves. He is very physically affectionate and his perverted side emerges around the person he loves.
He never lets go of someone he takes a liking to. If you don't want to be bound by him, keep your distance as much as possible. However, if you run away or intentionally avoid him, there's no telling what he might do. Once he becomes interested in you, there is no escape.
