Being Liam Payne's little cousin (One Direction/Niall Horan fan fic)

My name is Melody Payne.. Last name ring a bell?

One direction. Heard of them right? Super attractive, amazing boy band? Well, it just so happens, that im related to one of them, and i know two of them, both of the ones i know, happen to be my best friends, or use to be that is..we all had to go our different ways while they went touring.
Now, after about two to three years, I get a call from my cousin, telling me that he and the boys are coming to visit and he has a plan.... Oh boy, how can this go wrong?
