Oh!! But what about a Sastiel AU where Castiel is a teacher and Sam was recently hired to be a teacher's assistant.
Castiel doesn't want a teacher assistant, he believes he doesn't need one. He's been working at the school for a long time, and doesn't understand why they suddenly are forcing, requiring, him to have a teacher assistant.
Sam goes in knowing Castiel doesn't want one, and does his best to refrain from being upset about Castiel's stance on him helping him out.
The two have an interesting first meeting, but Sam does point out that with him there to help, Castiel can send Sam to do tasks he doesn't like to. Such as messing with the printer where everyone feels obligated to talk to you and ask what you're doing. Which saves Castiel from having to buy his own, it was in his cart already. And he's just there to help Castiel with whatever he needs, he's not there to take over.
Castiel, unfortunately, finds himself liking Sam's company. And how Sam knows how to help without Castiel saying anything. He especially hates how smug the principal is about Castiel and Sam work well together, as predicted. And Castiel tries not to think about the fact that Sam's on his mind a lot more than he should be.
Sam enjoys his job. He likes feeling needed, and loves working with Castiel and the students. The only thing that Sam hates is how much he's interested in someone who clearly isn't interested in him back. Not that Castiel has any obligation or anything, just, it'd be nice if Sam fell for people who would fall with him. But he ignores those feelings at the job, focused on whatever Castiel needs. Even the things Castiel won't voice but Sam's learned to anticipate, and hey, maybe Castiel doesn't hate him as much as he thought he would. And that feels like a win to Sam.
Over the course of the year the two fall really in sync with each other. Classes run smoothly, grades are at an all time high. And they're genuinely friends.
Castiel didn't realize how used he got to Sam's presence and help until Sam misses a day and Castiel's first class is a bit rough but he snaps into gear by his second class. But... He truly misses Sam and is grateful and happy when he returns the next day. Sam apologies, a family emergency, but things are settled. Sam notices a shift after that day, there's a lot more appreciation after that and Sam finds himself beaming at the praise.
As the year gets closer to an end, Castiel is trying to subtly ask Sam if he'll help him with the next school year. Which makes Sam laugh, he tells him not to worry, he can't get rid of him that easily. And Castiel is very happy to hear that.
