The first fan fiction I wrote has a story to it as well.
Once some time ago, my father made a friend as a young man and they kept in touch until my father got sent overseas (he was in the military).
One day when i was 12, turning 13 soon, James contacted my father while we happened to be in Texas helping my grandma. We proceeded to visit where I met his son- Thomas. We really hit it off. He thought I was cool for a girl, and I got a crush on him right away.
The internet was still a new thing and after a few months back home, we figured out how to talk in chats and instant messenger. Wanting to talk more with Thomas and learning he loved a lot fo the same shows I did.... we decided to write a Beast Wars fan fiction together. For the better part of a year we became fairly close as we went back and forth with the file. We even started writing about other things and doing RP chatrooms and stuff.
It's because of that story we stayed close enough to where when I was in a bad relationship- he was there to comfort me and have both of us realize we cared deeply for each other. Which led to our eventual marriage (with some other stories in between).
We still make fan fiction together when we are in the mood.
