Until his father died, he had to choose to become a hunter in order to live with his mother in the city. With a blood-stained butcher's knife, a childish boy began to crawl around in the wilderness. As the days got better, he slowly discovered that his life had not changed at all. Everything is like a rehearsed movie... So he fought back. So the more he fought, the braver he became. So he ends the end of time.
