They Don't Know About Us (Harry Styles/Brothers Best Friend)
She's Niall Horan's little sister. Niall and y/n are really close, she's just turned 18 and is thinking about exploring a music career, so Niall invites her to go on tour with One Direction. Niall has always been the protective older brother, but lately it seems like shes growing up faster than he can keep up with. So, Niall has given the band one rule: she is completely off limits.
Harry starts off treating her like Niall's little sister that's off limits. He still playfully teases and flirts with her, but that's what he does with everyone. Then one day his gaze lingers a little longer when Niall is not around, and when he talks to her, there is a softness in his voice.
She has always thought of harry as being her older brothers annoying best friend. Then, one day she starts to notice that his cheeky comments and casual touches make her feel different.
