Dean/Cas "It's a Terrible Life" AU

[stormydown]

I just rewatched "It's a Terrible Life" and now I'm on the hunt for a fic I read maybe a month or two ago set in that 'verse. I believe Dean has the same sales/marketing job he had in the episode, and Castiel is a cynical reporter/writer who's writing a story about Sandover. Every day he comes into Dean's office and hangs out with him, observes his day-to-day work, studies the innerworkings of Sandover, etc etc. Cas accuses Dean of not knowing his staff well enough, but Dean is good friends with Sam, who works in Tech Support. Stuff happens, Cas and Dean grow closer together, they eventually hook up, Dean considers taking a promotion in a different city because he's scared of commitment or whatever, I think Sam intervenes or gives advice at some point, you know the drill. I'm pretty sure it was a fairly long fic, but I can't remember the exact length. I thought I'd find it somewhere in my History but it's being elusive. Thanks so much for your help!
