Summary: Castiel has been demoted. He's not fond of his new duties, though he seems not to have a problem with the uniform.


Have been looking and looking for this fic and I can't recall its name or where its located
I remember the line "loves love" and I remember it was Castiel was demoted into a Cupid and he has basically been brainwashed into "loving love" and about every so often every other word is "love". Dean and Sam kidnap Castiel to help unbrainwash him. But his superior eventually finds him but seeing that Cas and Dean are "in love", the Cupid is overjoyed and allows Castiel to stay with Dean. and I believe the Superior just got promoted and then chose some weird boxer shorts with hearts all over them. a very amusing, a possible crack!fic. :D



thank you 
happily,
