Close As Strangers

Primrose Adkins, 13 years of age. Luke Hemmings, 14 years of age. The two were inseparable. They were so in love that they ignore everything and everybody around them. Until heart shattering news arrived. It had been 6 years since Luke Hemmings had moved far, far away. Primrose nor Luke have seen each other since then. But when Luke and his family finally move back, he is 20, and she is 19. The two bump into one another at a local gas station. Primrose doesn't recognize him, but Luke defiantly remembers her. What will Luke do to win Primrose back? Will they end up together again? Or will they always just remain, 'as close as strangers.'
