Story: Mistaken (Niall Horan fanfic)

Niall Horan Fanfic.

Cat is in love. Not like her prettier, thinner twin Caroline in love with yet another fast guy with rich parents and a private car...No, Cat is in love with an adult, intelligent, attentive, sensitive Harry. Or should we say Mister Harry Styles, her teacher English. Not that she ever told him, but she knows a 100% for sure that he is also in love with her.
Just Like she knows for sure that Niall, son of her fathers boss, is totally gay. Hello?! He'd rather give tennis lessons to Caroline than dating her! If that isn't evidence enough...
And So Cat doesn't mind sharing all of her secrets with Niall. She even tries out her kissing on him, so she wouldn't look too inexperienced when she and Harry finally can be together. No problem right? Unless not everything is what it turned out to be ofcourse...
