Hatred cannot fill the heart, only warmth can endure the long years. The most powerful thing in this world is never hatred, but hope; the most precious thing is never power and pleasure, but perseverance in the fireworks of the world. Those swords, swords, grievances and hatreds eventually turned into the grass and trees in the valley, the tenderness in the eyes, and the warmth passed down from generation to generation. There is no good or evil, no winning or losing, only the Valley of Forgetfulness, only a group of people, and only warmth year after year.
