It would be Lessons in Making Love if Sensei is chosen to teach anything
But I think observing Sensei learning love might really be the key concept here; a person who claims to have trouble comprehending what love means is now experiencing all kinds of love from all his relationship with everyone and learning them: pure, unconditional, unrequited, codependent, obsessive, manipulative, adulterous, forbidden, and incestuous.
It's just who actually is observing is still up in the air (maybe it's all those supernatural BS beings perhaps?)
