Renegade (Phandom Big Bang)

It's World War 2. Phil, a young German soldier, is stationed in Denmark. There he meets Dan - a rebellious Danish school boy who is intent on making his job hell. But before long, they realise they have more in common than they'd have thought. How do you hide a friendship when you come from two different sides of a war? Fluff/angst/war/violence/death (it's really good)
