A case comes up at a councelling retreat and Sam, Dean and Cas go to check it out. Sam snatches up the only job vacancy forcing Cas and Dean to go in as a couple. None of them expect the events that unfold (but they kinda do).

Dean starts wearing the glasses used for seeing hellhounds around everywhere to discover other things hidden from his vision. At first he notices nothing. Until one day, Cas shows up and Dean can't seem to take them off. Based off a post I saw on Insta about what if Dean could also see Cas' wings with the glasses on. Not my original idea:)

Dean is an angel, and a guardian angel at that. He's one of the best of his kind. So when a very important human needs watched over, Dean is on the job. The problem is, the human can see him. This might be harder than Dean thought. Disclaimer: Almost all characters do not belong to me. They belong to the writers and creators of supernatural.
