You were sitting quietly on a park bench and reading a book. But suddenly you felt that two people were approaching you. Distracted from the book, you saw two men. The first one had white hair, a cloak and armor. A medallion hung around his neck. The second one with black hair, the man's eyes were closed, he was also dressed like the first one. —Hey, do we know each other? the white—haired man said. "You seem familiar to us," the black—haired man said.
