Spin-off of Doukyuusei, following the creepy teacher. Only one chapter with the Doukyuusei MCs. Generally all around creepy with multiple age gap pairings involving teachers, with the whole premise being 'well they immediately got together after high school graduation, so the teachers are somehow virtuous because they refuse to sleep with their students, aren't they great guys?' vibes. I'm not here for it, but it's not as gross as an actual relationship. Also I just don't see any chemistry here, so it's just uncomfortable, whereas the scene in Doukyuusei was creepy. NOTE THAT THE OFFICIAL TRANSLATION CHAPTERS COME AFTER THE FIRST SET
