When the End Comes, I Have a World Tree

Some people say that there are two things in this world that are eternal, one is the sun, moon and stars hanging high above our heads, and the other is the silent persistence hidden deep in everyone's heart. Under the apocalypse, order collapses. The main theme of the apocalyptic world is that people will be punished if they don't do it for themselves. People with good intentions are often ridiculed and plotted by the world. However, there will always be people who silently move forward towards the same goal in different ways.
