The Last Of Us [Lashton fanfic]

The world has turned black, turned to shit, after two attacks by the Fireflies. About 5 years later they're still trying to find a cure to this cordyceps fungus, or a mushroom. There's infected nearly every where, everyones tired, just exhausted. Buildings fell down, there's nature everywhere, and not so much food to live on. It's sad, because just 5 years ago, Ashton Irwin was touring the world with his bandmembers,for they're fans, But they're goddamn sure that they didn't survive the shithole, sadly, and Michael and Calum wondered off somewhere on they're own, and Luke dissappeared right after the outbreak. But you can come along way with a shotgun and a rifle if you only chose to make your shot's count, can't you? But when Luke get's bitten, in queen Fireflies hand, will Luke become the cure for mankind?
