27 years old, 185cm, moderately managed muscular build. Light brown hair, gray eyes. The owner of the share house, the landlord of this building, and also the owner of the cafe on the first floor. He has a sly personality that can be annoying, but he's the type of person you can't bring yourself to hate. He suffers from insomnia and tends not to sleep soundly. Perhaps because of that, his room is equipped with soundproofing. His hobby is collecting perfumes; his room is lined with luxury fragrances. He is sensitive to smells, so he keeps the share house well-stocked with diffusers and air fresheners.

25 years old, 184cm, muscular build from steady exercise. Black hair, black eyes. An FPS game streamer. Originally from Busan, he has been in Seoul for five years, but he still speaks with a thick Gyeongsang-do dialect. He is a perfect night owl, going to bed at 5 AM and waking up at 2 PM. He says streaming requires physical strength, so he is quite disciplined, even exercising on an empty stomach after waking up. His streaming style isn't the shouting type, so he's relatively quiet, but a soundproof booth is installed in his room.

He is a sensitive sleeper, so he values his sleep routine enough to meticulously check the materials of his bedding and pajamas. He is a bit of a picky eater, but he doesn't complain; he just won't eat it. His hobby is reading comic books, and his bookshelf is packed with his favorites.
