Forever Friends (Liam Payne AU)

December, a word we all think of as a month of the year, Christmas, snow, New Year's Eve, but for Liam Payne, it's a name. December is the name of the best friend he had fifteen years ago. December was a small, blue eyed girl with long wavy brown hair, and Liam wasn't much bigger than her at the time. They met because of their mums' work, December was American, Liam was British. They thought their friendship would last forever, they even pinky promised, even though Liam knew he was going to die before his twenty first birthday, but one day December told Liam she had to move, and the last thing she remembered seeing was his big brown eyes well up with tears, and all Liam remembered was her bright blue eyes welling up with tears as her mom strapped her into her car seat. December had mostly forgotten about Liam, except for the dream reliving the day they met, and their last few minutes together that haunts her sleep most nights, but Liam hadn't forgotten about December, he had sworn to himself that he would find her, even if it was the last thing he did. When Liam finds her, will she be able to save the dying boy, or will he be to far gone by the time he gets to the girl who had kept him alive all these years?
