If he had been with me, everything would have been different…

Autumn and Finn used to be inseparable. But then something changed. Or they changed. Now, they do their best to ignore each other.

Autumn has her boyfriend Jamie, and her close-knit group of friends. And Finn has become that boy at school, the one everyone wants to be around.

That still doesn't stop the way Autumn feels every time she and Finn cross paths, and the growing, nagging thought that maybe things could have been different. Maybe they should be together.

But come August, things will change forever. And as time passes, Autumn will be forced to confront how else life might have been different if they had never parted ways…
