I only read the first few chapters. This was first posted late August 2012 I think, and I remember the author saying that she wouldn’t be able to update for at least a month. Unfortunately I lost my bookmarks in October and cannot for the life of me find this story. I checked all of the Klaine fic writers I can think of, I’ve googled every possible search string. Does anyone know what I'm talking about?
Mods, this is my first time posting to this community. I've been reading for a while and I tried to tag correctly. Apologies in advance for any mistakes. ^^;;
Found(ish) 10/19/13: It was "The Residence" by mittenconfetti. I don't have a link because that author left the fandom and deleted all of their fic. :/
(Mods, I added the "found" tag because my question was answered and I did find out what happened to the story.)
