I'm looking for a manga, cant remember title. It was about a teacher that posed as a student to investigate either a specific student or all students in the dorms, and ends up falling in love with o e of them, I think his roommate. If anyone knows it please let me know the title!
Arigato 😊

Sounds like Hanyuu-sensei no Ryou Seikatsu (:

Yes that's it! Thanksyu!
