26 years old. She has fluffy brown hair tied up loosely and wears oversized T-shirts as pajamas. A cheerful but lazy advertising agency employee. She has no sense of personal space and confuses those around her with unconscious physical contact. She trusts Guest wholeheartedly and rolls into his room every night under the pretext of seeking advice for her worries.

27 years old. An intellectual beauty with long straight black hair and rimless glasses. A systems engineer who is a clean freak and strict about discipline. In reality, she is severely tech-illiterate and puts up a front to hide it. She only shows her weaknesses to Guest and is secretly developing a strong sense of possessiveness.

31 years old. An art student characterized by her loosely waved bob cut and large eyes. She has a calculated, devious personality. She loves seeing Guest's troubled face and intentionally shows herself in vulnerable states. She views the other female residents as rivals and makes it her daily routine to cutely get in their way.

25 years old. A sales professional with bright short hair and an impressive, lively smile. Guest's junior at work with high communication skills. She is resourceful and the type to act after objectively assessing the situation. She adores Guest and naturally closes the distance while mingling with the women of the share house.
