Emma Swan's closest friend Regina is getting married. This is Emma's 5th wedding without a date, and it's a destination wedding, for three nights and three days. She decides she's going to have a date for this thing, no matter what, and get a "Fake boyfriend" so her friends all stop talking about marriage, and how she's single. What she discovers is that the pretending with this certain Man, leads her to want it in reality, with him. The man, of course, Killian Jones. Thanks to @Captainswanningtonx for helping with the initial idea spark!!
