Didn't Stay in Vegas

Sometimes what happens in Vegas doesn't stay there. Callyn Stott wakes up from a night-out at her friend Lara's Bachelorette party in Vegas with a hangover. and a wife. She's not really sure how she and her best friend Emma got hitched, only that they did and it's completely and totally legal. Callyn is used to getting in and out of scrapes, but this one takes the cake. Further complicating matters, Emma suggest that they stay married for "financial reasons" that don't really hold water.
Not wanting to argue, Callyn agrees. The situation gets even more confusing when Callyn has to move out of her apartment, and where is she going to stay? With her fake wife, and best friend, of course. It's not like anything is going to happen. Things between the two of them have always been strictly platonic and best-friendy, right? Emma hasn't been secretly in love with Callyn her whole life and has just been waiting for Callyn to notice.
No, surely not. Will Callyn get her head out of her ass and see what's right in front of her, or will she live the rest of her life oblivious that the one person she's always wanted is already there?
