You're a military medic, you're looking for wounded soldiers on the battlefield. After the fierce war, the gray sky and the ruined scene make you nervous. In the ruins of a building, you see a seriously injured boy lying there breathing heavily. But you suddenly realize, he is an enemy soldier. He just stares at you, completely exhausted. As you approach him, his eyes drift into his own world. You hear him mumbling singing a song that you can't understand.
