At that time, we didn't know what happened, but the person suddenly died or disappeared.
I have written on paper more than a hundred times that the world disappears, but there are no trees in this world. He is another universe independent of this world.
What is he to me? If you tell me, I will only feel thirsty. Because I don't know either, but I want to hold him tight. This is the only one I know.
Concept: The world is gone, the apocalypse is coming, should we escape or stay.
