Everything Has Changed (Harry Styles fanfic)

My name is Allison Clark.
I’ve changed a lot, maybe for the worst. I was once in love. It was the most amazing, stressful, incredible, impossible emotion I ever experienced. I hated it. It drove me insane. But I couldn’t let go of it. I still can’t.
His name was Harry. We were perfect for each other. I was always there for him, and he was always there for me, until one day, when everything changed.
But I’m getting a bit ahead of myself. I guess I will tell how us, totally strangers became best friends. I never thought it would end, but every good story has an ending. This is the story…. Our story.
