I remember the seme being a guy who can master anything in 3 hours or something. He creates a game/dating sim and decides to test it out. He meets the uke (who apparently is a character he designed to be plain and average) and falls in love. There was also something about wanting to see the sea..?
they were both high school students i think and the seme is the one who walks in on the uke. there was something about watching porn together i can't really remember.
I love that manga!! http://www.mangago.zone/read-manga/toshigoro_no_otokonoko_to_are/
i think its a oneshot in a collection of stories. this student (uke) always bosses this teacher (seme) around, but then the teacher basically kidnaps him and plans to kill him after having sex or something?? and he apparently has done this to other people before? but instead of being scared the uke just says something like "you'll always be below me" and the seme is like "you're the best" and doesn't kill him
