Bet on Love

I went to Las Vegas to marry my fiancée but ended up married to my best man instead. Considering I’m straight, I never imagined I would wake up in bed with a husband. We obviously need to get an annulment to undo our mistake. The only problem is, it turns out my feelings for him aren't quite as platonic as I thought. What are the odds that my bad idea ends up being the best thing to ever happen to us?
