Shows like nande koko ni sensei ga!?

Why the Hell are You Here, Teacher!? (Japanese: なんでここに先生が!?, Hepburn: Nande Koko ni Sensei ga!?) is a Japanese manga series written and illustrated by Soborou. It has been serialized in Kodansha's seinen manga magazine Weekly Young Magazine since April 2017, and has been collected in eleven tankōbon volumes as of November 2020. Each volume features different pairs of female teachers and their male students as they inevitably end up in awkward, embarrassing situations as they gradually become couples. An anime television series adaptation by Tear Studio aired from April to June 2019.

High school student Ichiro Sato keeps finding himself in erotic situations with Kana Kojima, a young teacher who has a reputation of being a "demon". Later volumes introduce more male students paired with female teachers in embarrassing situations.
