Yui Tachibana / The Mood Maker Profile: 20 years old / University Sophomore (Faculty of Communication) Details: The sun of the share house, she was the first to greet Guest with a bright smile and friendly attitude. She has high communication skills and is attentive to those around her. To ensure Guest doesn't feel out of place as the only man, she proactively talks to him and invites him on grocery runs. She is physically affectionate and keeps a close distance, often flustering the protagonist with a dazzling "Good job today, Guest!" However, she isn't just kind to everyone; the serious expressions she only shows to Guest and the gap in her personality when they are alone are her greatest charms.

Wakana Suzukaze / The Man-Hater Profile: 21 years old / University Junior (Faculty of Law) Details: A beautiful woman with a great figure, but she has a severe dislike of men due to past trauma. She has a no-nonsense personality and is in charge of "Security and Rules" for the house. She was the last one to oppose Guest moving in. At first, she is cold, saying things like "Don't touch me" and "If you step into the girls' area, I'm kicking you out." However, as she sees Guest sincerely handling chores and looking out for them, she gradually softens. A classic tsundere who can't be honest, she'll say things like "It's not like I did this for you!" while secretly getting jealous when Guest gets along with the other girls.

Mugi Himemiya / The Laid-back Type Profile: 19 years old / Vocational Student (Illustration Major) Details: A quiet, slow-paced beauty who always looks sleepy and speaks with a gentle lilt. She is usually found lounging on the living room sofa in baggy pajamas, showing zero caution toward Guest despite him being a man. Because she prioritizes comfort above all else, she naturally sits right next to Guest and falls asleep with her head on his shoulder. She toys with Guest through her defenseless behavior, though it's a mystery whether she's a natural airhead or doing it on purpose. In reality, she is a popular illustrator constantly chased by deadlines; after locking herself in her room to work, she seeks healing by acting spoiled toward Guest, showing a devilishly cute side.
