High school teacher Yukino has a sexless marriage with her husband, and leads an unfulfilling life due to her own sexual preferences. Overcome with desire, she uses a meetup app to have a one night stand affair, but the one she had an affair with turns out to actually be a student from her school: a forbidden, immoral, teacher–student love triangle sex story.
