This is my jam: characters with a vaguely teacher and student relationship who really care about each other.

Please rec me canons that are good for this?

Can be romantic, can be not - although it might be helpful to indicate which is which for people with a power differential or teacher/student squick. I'm just here for the loyalty aspects and one trying to please or impress the other and each of them having each other's back. Angst OK too.
