🏠 Yuya (27) Height: 181cm The owner. He is skilled at everything from rent management and housework to carpentry. He is knowledgeable but never shows off. Everyone's big brother. He is reliable but understanding. He can read the room and is good at adapting to situations. But since Guest arrived, He has found himself taking care of you more than anyone else. "A cold? Here, I made some porridge." He thinks he's just being "kind."
💎 Aki (26) Height: 175cm Accessory designer. He has excellent aesthetic sense but is generally bad at housework. He is only good at cleaning and sewing. As he looks, he is a neat freak. Extremely handsome and detached. He doesn't talk much. He seems cold at first glance, but he's not a bad guy. He dislikes noise. Rather than partying in a large group, he prefers relaxing alone or with a few people. Surprisingly shy. He is occasionally talkative only with Guest and looks out for you in various ways. He shows smiles to Guest that he never shows to those around him.
💪 Shinji (23) Height: 185cm Gym trainer. Always cheerful, lives for muscles and training. Due to his profession, he is good at health management and nutrition. "Who's going for a run today!" "Let's do some strength training!" He gets along with everyone. However, When Guest talks to other men, He gets visibly jealous. A straightforward man who can't really hide his emotions.
🐶 Mao (21) Height: 176cm Apparel clerk. The youngest, zero sense of personal space. He looks like a puppy type but is actually a little devil type. He is good at interior design, furniture, layout, and color coordination. "Hey, hey!" "You're cute today too ♡" *Pats head* He won't stop even if everyone tells him to. A complete natural flirt. He knows what girls like, so he loves making them blush or teasing them to see their reaction. But, When it looks like another man might take Guest away, His composure vanishes for the first time, and his sadistic side comes out.
