Gotta Be You - A Harry Styles Fanfic

Lily and Harry have been best friends since the very beginning, but with his recent and very quick rise to fame, Lily sees less and less of him what with his tour taking him around the world. She's a grounded, down-to-earth girl and isn't ready for a life of fame where people know her as Harry Styles' best friend. But things in life are taking a turn for the worst, and Harry knows the secret she has been desperately trying to hide for almost a year now; he's becoming very protective and people are starting to notice.
She knows that her education is her biggest priority, yet something has changed between the two of them since Harry returned from his eight month trip abroad. They're starting to see each other as more than friends, but is Lily willing to give up on her education, her boyfriend whose hiding a deep secret and, most of all, her infamous status for a boy who knows her better than herself?
