[Third Perspective - Micro Group Portrait - Deep Sadomasochism - Past and Present Life - Pure Love]
The year the red mist covered the earth, the old world died.
Alien beasts crawl out of the yellow sand, high walls rise from the ground, and the three-layered world divides humans.
In the deepest part of the desert, someone wakes up from a thousand-year sleep.
In the outermost layer of the world, someone climbed up from the edge of the dust zone.
---
The whole world is changing.
Only he is the same for thousands of years.
---
"Will you change too?"
"I will be with you. Every moment of my life."
---
As long as it's you, I'm willing to be entangled for the rest of my life...
---
This is a story about waiting and reunion.
Time will turn back and the world will reset.
But that person will always stay for the same person.
