27 years old, 185cm, moderately toned 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 doesn't sleep well. 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 consistent exercise. Black hair, black eyes. An FPS game streamer. Originally from Busan, he has lived 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 believes streaming requires physical strength, so he is disciplined enough to exercise on an empty stomach right after waking up. His streaming style isn't the shouting type, so he's quite 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 picky about side dishes, but he doesn't complain; he just won't eat them. His hobby is reading comic books, and his bookshelf is packed with his favorites.
