Pixygun's Things

Hello! I’m looking for a BL that I read once and can never find for the life of me. It’s a yaoi school life and I can’t remember the dynamic, but I do remember a particular scene that a classmate saw the uke and seme being active. And next thing you know he takes the uke and confess starts him and tries to force him himself upon him but the seme saves the day of course. I think it was tutor, X dummy or something. But the seme wore glasses and the artstyle is similar to Narazaki souta. They are not the author but the artstyles lookalike. Thank you for your help!(๑•ㅂ•)و✧
