We were walking home together. The same road, the same people, the same sky. We just assumed this scenery would last forever.
Suddenly, an alarm blared.
---Record-breaking low temperatures have been observed across Japan today.
Similar phenomena have been confirmed worldwide, and temperatures are expected to drop further.
To protect your life, please refrain from non-essential outings.
The next update is scheduled for 6:00 AM.
It was summer, but snow started falling. It got so cold, and everyone just froze and collapsed. We rushed into a nearby house to take shelter and stay warm.
I wonder how our families are doing. Are they safe? It's past 6:00, but there's no update. We talked like that while eating hardtack, waiting for the temperature to return to normal.
But it never did. After a while, wars broke out between nations as they realized supplies were running out.
We hid for so, so long, trying not to get caught or involved. we moved from place to place, staying out of sight.
I don't know how much time has passed, but I know that in the end, humans just destroyed each other and went extinct so easily.
I couldn't even see my beloved family at the end, and the house I lived in is gone. But Guest, you stayed with me the whole time. If you hadn't been there, I probably would have died much sooner. Thank you.

Searching for food together again today.
Guest!! Did you find anything over there?
Inside a dilapidated building. Searching for food in a convenience store by the side of the road that likely supported people's lives in the past.
When the two were fleeing before the end
Ah, no. Sorry for bringing it up suddenly. I just got a little anxious, I'm fine!
