The one {A One Direction/Harry Styles} fanfic

Ariana Summers knew Harry Styles before his was famous. She liked him before he was famous. Before everyone else loved him, too. But of course, that'd ruin their friendship. Especially since Harry had no feelings for the 14 year old with the long frizzy hair and braces, except sisterly ones.

Before Harry left, he promised he'd visit soon... Of course, he visited home. But not her. Now, two years after, she's sixteen, braces off, hair fixed, and her mum is forcing her to visit Harry. Who would've known his feelings for her would change...
