Derek and Ariana have never really gotten along that well. Always constant arguing when they're around one another. Everyone were sick of it. It had to be stopped.
Now it may be hard to believe, but there was once a time when they got along. Pretty well, actually. They were best friends. All the way from preschool to high school.
But it was that one day at school when everything fell apart. Everything that they ever had. Gone. All because of a mistake. A mistake that ruined a perfect and beautiful friendship.
If only they could go back and change it. If only they could somehow travel back in time to when they were 17 years old.
Maybe, just maybe, they could start over.
