I'm looking for an old Dean/Cas fic where Dean has always been a girl. It was an all human AU that took place post break-up. Dean had been in a relationship with Cas when she was still underage, and had lied to him about it. They broke up when he found out she wasn't legal. I think it started out with him seeing her again for the first time in a while in a grocery store or something like that. Pretty sure they got back together at the end of it, or it had the implication that they would. I think it was a pretty short fic, but it's been niggling at my brain and it's going to drive me crazy until I find it again.

Also, if anyone knows of any other fics where Dean is underage and lies to Cas about it I'd love a rec!
