Eternity (Larry Stylinson AU)

Harry Styles has late-stage cancer. His chances are slim, and he already feels like he's losing the fight. Then he meets Louis Tomlinson, who's dating Harry's nurse and has a re-occuring brain tumor. Louis starts lifting Harry up and making his life with cancer a little less painful, while Harry forces Louis to cope with reality. Sometimes, in the most unlikely of places at the most unlikely of times, people have a way of finding each other. But sometimes not even love is enough to save you.
