Hi! I am looking for an AU where Dean is going to Sam's wedding, and Castiel accompanies him. They're friends at first, but it ends up Dean/Cas. No supernatural elements at all - Dean is (if I remember correctly) a nurse, Castiel is a doc.

Sam is marrying Ruby, and both are ex-junkies. Dean hasn't seen Sam in a long time, and only goes because Cas goes with him. The wedding takes place at Bobby's.

Any help would be greatly appreciated!

ETA: found! Thank you chiya_chan!
