Ashley Styles is Harry's sister. She hasn't seen her little brother in over five years. She arrives in London, excited to see Harry, but there's something else on her mind. And when a certain blue eyed british boy begins to fall for her, things get even more complicated. But as Louis says: live your life for the moment, because everything else is uncertain.
