He was my best friend. He was there to hold me together while I was breaking, he could make me laugh when I was on the verge of tears, he protected me, he saved me when I didn't realize that I needed it. He helped me through a lot. Which is precisely why I started to fall for him and that terrified me. I didn't want feelings to get in the way of what we had.

But no matter how hard I tried I couldn't help but fall in love with him. I'm Natalie Anne Hollandsworth and this is the story of how I fell in love with my best friend.
