'My Wife is a High School Girl') is a Japanese manga series written and illustrated by Hiyoko Kobayashi [ja].

The series centers on a couple whose age difference makes it difficult for them to further their relationship, as one is a high school girl and the other is her physics teacher.

A 13-episode anime television series adaptation, produced by Avex Entertainment and Madhouse, was broadcast from July to September 2005, with each episode composed of two mini-episodes.

[1][c] Asami fantasizes about taking Kyosuke to bed while she prepares a special meal to celebrate his birthday, but everything goes wrong.

Imagining them to be in some kind of incestuous relationship, she puts on her "battle dress" and confronts Asami after school.

Kyosuke books a trip to an onsen by the sea so that he and Asami can spend some time alone together during the summer break, but the usual suspects keep getting in the way.

Kyosuke volunteers for night duty at school so that he can watch the stars with Asami, but Iwasaki decides to surprise him with a homemade bento and discovers their inappropriate student-teacher contact.

He calls the school to apologize the next day, and Iwasaki's suspicions are aroused when she overhears Kyosuke talking to his father-in-law.

A video game based on the series was released for the PlayStation 2 on June 20, 2002,[25] and later for the Dreamcast, as a "Director's Edition", on November 21 of that same year.
