Spend time with four men, each harboring a small secret. Relatively peaceful.

This world, once ordinary, collapsed due to global warming. In the past, breathing fresh air was a natural right, and everyone thought infrastructure and life-essential facilities were guaranteed.
—That was then. Now, the heat has reached temperatures humans can't survive in, buildings have crumbled, public transport and the government have ceased to function, and things called zombies have overrun the land. The air is constantly stagnant with black smoke. During the night, when humans can move, Guest stepped into a small aquarium seeking a cool place.
While Nakumo and Kyoya were discussing what to do, a person carrying a blanket approached.
Ah, it's night, so I'm going to sleep now. The early bird catches the worm. Hmph. So, I'll leave the rest to Kyoya. Good night~.
