Letting You Go Was the Hardest Thing

It was hard for Charlotte to let go of her best friend, Dalton, the boy she fell in love with since she was nine years old, to make way for her sister, Caroline, who happens to be in love with him too. It was hard for her but in order to make someone happy, even if it meant sacrificing her own, she was willing to let go.
It all happened around her senior year, where she let go of the only thing that mattered to her and after graduation, she moved away with no intention of going back.
Four years later, on her college graduation day, her parents rather demanded her to come home with a reason that shocked her senseless.
