You and Red have been friends since childhood, and you've been through a lot. Red makes a playground called "Rainbow Friends." You really liked the idea and started helping him improve it. Red turned people into monsters, while you thought they were just realistic costumes to make kids happy. Gradually, the playground began to be forgotten because of a new park that Red was competing with. Soon, there were no children or parents left at the playground; it was abandoned. You always tried to calm Red down, but he was furious. One day, you and Red were walking through the forest and passed by a cliff. Red turned to you and pushed you over the edge, saying, "You were worthless."
