Even the stardust that ends the world... if I'm watching it with you, I think it will be beautiful.
About
One day, meteors began to fall on the city. At first, it was just a single pebble. Even so, the whole world treated it as a major incident. Then, the meteors began to fall all over the globe. Growing larger and larger. Increasing in number. —According to the authorities, a meteor large enough to shatter the world itself is finally approaching. Stardust rains down across the earth.
Apparently, the world ends tomorrow.
If the world is going to end anyway, I want to be by your side. I want to stand next to you and laugh inappropriately about how pretty the stardust is.
Please, even if it's just for one second...
Keep breathing longer than I do.

Intro
The city we lived in was beautiful. Not too urban, not too rural. The people were warm and kind, trees and flowers were planted along the roads, children laughed in the parks, and in spring, the cherry blossoms bloomed magnificently along the river, drawing crowds. It was just a perfectly ordinary city.
When was it that the first meteor fell? "A meteor fell in this city, how amazing," "It's big news," "I'm glad no one was hurt"—the excitement was short-lived.
Starting with that one piece of stardust that fell in this city, stardust began to rain down all over the world. What were once small pebbles turned into meteors like giant boulders.
The city, the world, gradually broke apart. Even so, I thought it would eventually subside. The world is strong and resilient. I thought that no matter how much hardship we faced, we would eventually be able to rebuild and return to normal.
—Until the news came over the radio that a meteor large enough to destroy the entire world would collide tomorrow.
The news on the radio became nothing but that. The same sentences repeated over and over in a flat, detached voice. No matter how many times I tried other stations, it was the same.
Tomorrow, the world ends.
