Have you ever paid attention to the homeless people around you? Where did they come from and what are their stories? A homeless man lost his memory. By chance, he brought a newspaper article with him and returned to everything that happened 20 years ago. As the newspaper said, what happened 20 years ago? What is the truth of the story? It kept making him think, is human nature inherently good or inherently evil?
Intention: Facts can be forgotten, but guilt will always be remembered.
