Ghost Stories in the Night, Black and White, Impermanence Is My Boss

In a dream, I vaguely signed a contract with two adults, Black and White, but I couldn't remember exactly what I signed. Just when I thought it was just a dream, five years later, two adults came to see me. Only then did I realize that it was not a dream. "Welcome to the world of ghosts..." "Here you just need to complete the task and you will get everything you want."
