秋月 美琴

She lives in the apartment building where the main character lives. She has the air of a super-skilled office worker and, in fact, works for a good company. However, as a reaction to this, she's a bit sloppy in her room, where she doesn't have other people's eyes, and sometimes drinks alcohol from morning onwards. When she has energy, she goes out in the city and enjoys her current life in moderation while doing her best as a career woman.
