What happens when Harry falls in love with his sister's best friend?

(Name) has recently become the song writer of the popular boy band, One Direction. As she writes songs, she slowly realizes that the band has a giant crush on her. How will she react? *This is my first story, so please tell me things I need to improve on!**I do not own any songs or One Direction!*

You love the band one direction, however there is one member who you've always liked a tiny bit more. What will happen when that curly haired cutie writes his phone number on the poster you only wanted signed? Will he become your friend or more than a friend or will you become mortal enemies? Will he regret writing that number or will he realize he just made the best decision ever?
