I want to read about the first time someone tells Cas they love him or he says it to them, from his point of view please. Don't care who it's with, anyone at all will do. I just would like some insight into his mind the first time he hears it or realizes he feels it for someone.

Non-AU please. In the sense that it's set in the same world as the show. Obviously, it'll have to deviate from canon :)

Thanks!
