I didn't use translation so this might not be accurate. They don't end up together, dark haired dude cannot kill the light haired because light haired reminds him of someone. Light haired dude goes back to his base, they went their separated ways. The end shows a sniper (dark haired sniper) covered in blood which I assume he died after he separated away with Light haired.
Just correct me if I'm wrong lol
