Help finding this Korean movie?

In the movie it's the Korean war and a group of North Korean soldier and a group of South Korean soldiers get lost and they both end up at this isolated village (the villagers don't even know that there is a war) and the soldiers fight but they then start to get along while living in the village. And there is this really weird girl who dies at the end (all the soldiers die too ... you gotta love Korean movies) The movie isn't that old.
