Dean/Cas fake reality fic

[avat13.livejournal.com]

I am looking for an older Dean/Cas fic where Dean and Cas meet fall in love and get married.They are going to try and adopt a Kid when Gabriel shows up and it turn out he put them in a fake reality where they didn't remember they were a hunter and angel to teach them a lesson. Cas was professor of religious studies I think and he and Dean go to a staff party as date or something. Does anyone know what fic this is?
