The Secret Rocker and the Pop-star (Niall Horan FanFic)

(MORE PAGES THAN SAID)
'Hi, my name is Marissa Eden. I like to be called Mari though. Pronounced Mary with teachers and fellow students, but otherwise pronounced differently(Mar-i). I put videos on Youtube of me "rocking out". I guess you could say thats loserish. When not making videos, I have a disguise.' What happens when she literally runs in to a blonde pop-star that is 1/5 of one direction? And he recognizes her from her videos? Will she change her disguise? Will she let out her secret? Or will she just have to make the boy band promise to keep her secret?
