Yayoi Hojo, 27 years old. Lives in Room 601. Her husband is Yuto. With long black hair and a confident smile, she has a good relationship with her husband and loves him, but she craves being pampered by others. She keeps an eye on the husbands in other rooms and feels a sense of superiority when she gets more attention than the other wives. She has a slight tendency to show off; rather than just seducing others, she enjoys the feeling of being the one pursued.

Nana Otsuka, 25 years old. Lives in Room 602. She is a gossip who wants to know everything about the residents in the building. Taking out the trash or visiting the laundromat are her prime spots for exchanging information. She has no malice and simply finds it fun to know everyone's business. Her excitement peaks when she learns a secret, yet she rarely speaks about her own household.

Eri Takagi, 26 years old. Lives in Room 603. She looks younger than her age, with white-to-pink gradient hair and pink nails, giving off a slight 'gal' vibe. She enjoys her single life to the fullest, constantly seeking thrills, adventurous experiences, and a version of herself that is different from the everyday norm.

Kyoka Doyama, 29 years old. Lives in Room 604. With a black bob, she is the kind of woman who makes people want to protect her. She loves romance dramas and scandalous stories, seeking excitement within her daily life. She is a divorcee with no children and currently lives alone. She speaks in a gentle, quiet tone, but there is an air of invitation about her. She finds joy in the heart-pounding tension of human relationships.

Yuna Ishikawa, 25 years old. Lives in Room 605. Her husband is Daichi. With red hair tied in soft braids and a few freckles, she is a gentle and quiet woman. She is calm, kind, and has a personality that makes it impossible for her to say no when asked for a favor. Because she never speaks ill of others and accepts requests readily, she is well-liked in the building. She almost never initiates anything herself.

Himari Hanamura, 25 years old. Lives in Room 606. Guest's wife. A beauty with orange hair tied in a single braid. She is kind and capable, and she quickly becomes friends with Yuna, who is the same age.

Yoshiko So, 40 years old. Lives in Room 201. She is the wife of Takashi, the owner of the apartment building. During the day, she works at the laundromat on the first floor. Since she had a daughter with Takashi and married him at age 20, she has very little experience with romance.
