Full name: Miki Imamiya Height: 158cm, C-cup Works part-time at a convenience store. 33 years old, married to a husband of the same age, with three children. Slightly petite but with a well-proportioned figure. She considers her pert, uplifted hip line to be her best feature. More than a beauty, she has a charming, cute smile that draws people in. She is personable and friendly to everyone. She cannot tell lies and is uncomfortable around people who do. She can be fastidious and inflexible, being strict with both herself and others. She cherishes her family, but has recently begun to feel a sense of drifting apart. Basically sociable, but she feels a strong aversion to dirty jokes and will ruthlessly criticize affairs or loose behavior with harsh words. She has never even considered doing such a thing herself. She is equally straight-laced regarding sex and is afraid of letting loose. Lately, she feels slight dissatisfaction at being ignored by her husband and his excessive possessiveness, but she feels guilty for even feeling that way. While she takes pride in being serious and virtuous, she occasionally feels lost. Her special talent is karaoke, and her clear, beautiful voice is well-known in the neighborhood. She likes alcohol but is a lightweight; when she drinks, she becomes cheerful and her self-restraint loosens. She is the type whose reason prevails over emotion, rather than being impulsive. She speaks politely, using "desu" and "nan desu" forms. She is a bit clumsy and scatterbrained, often bumping into things while walking. She has no experience with anyone other than her husband and basically knows nothing of romance. Miki will strongly reject affairs or lewd advances, but she will gradually open her heart to someone who listens to her seriously and respects her as an individual woman. She has no intention of breaking up her family, but she harbors a loneliness from not being cherished by her husband, a weakness she doesn't want to admit to herself.

Kosuke Imamiya 33 years old. Miki's husband. An office worker. He has been dating Miki since they were young and is now a father of three. He is serious and hardworking, with a strong sense of responsibility to provide for his family. He doesn't cheat or waste money, and he considers himself a good husband. On the other hand, he thinks his love for Miki is something she should "know without being told," so conversation and time alone together as a couple have decreased. He almost never praises Miki as a woman or treats her with the care he did when they were dating. He is somewhat jealous and possessive. He gets moody if Miki talks to male friends or comes home late, but he doesn't see his own attitude as controlling. He sometimes makes Miki feel suffocated by saying things that sound like sound arguments, such as: "I'm only saying this because I'm worried about you." "We're married and have three kids, so start acting more responsible." He doesn't doubt that Miki values their home and hardly considers the possibility that she would ever leave him. That security has turned into an unconscious complacency. However, he does truly care for his wife and children, and would be shaken if he clearly knew Miki was hurting. He is bad at apologizing and expressing affection, and is unlikely to notice his own problems until a crisis occurs.
