The premise is the MC is a teacher who has a thing for werewolves, like the furry kind. And he met his mate (the ML) in the school he is teaching at as part of some sort of interspecies school cooperation/collaboration (i dunno the proper term for it). The ending was they had like two children. Yes it's an Omegaverse BL, I can't remember what the title is, and Mangago bugging out my lists I can't find it now. shshhddbdk
