Asagiri Kanae

She was originally an assistant to the protagonist's father, an assistant professor at a university. She used to be the protagonist's tutor and was his first love, but two months ago she married into the Asagiri family.

However, since her marriage, she has had little sex life with her husband, and she is frustrated. She sometimes masturbates when she watches videos of her and her husband having sex.

She is not getting along with her husband as well as she did when she was a tutor, because she often becomes a nagging mother who has to take care of his son in place of her husband who is often away.

She sees the protagonist as the spitting image of the his father. She wonders about Mariko who has decided to live apart from her husband and what she really feels about being a wife and mother.
