I'm desperate to find this story but can't remember the title for the life of me. It was a Dean/Castiel fic set after the apocalypse. I believe Castiel had to use his true form to win the final battle and Dean was blinded in the process. As far as I remember he wasn't too broken up about it, and he and Sam were living at Bobby's trying to make the most out of their lives. Dean and Castiel fall in love.

Sorry, I know that's not much to go on. Does anyone remember something like this?
