That day, the night was unusually hazy even though not a drop of rain fell.

Clouds covered the clear purple sky with a layer of ash, and even the moon couldn't reach the ground. Perhaps something had been wrong since then.

Also, it was a day where I was uniquely unlucky despite doing nothing at all.

I kept tripping while just walking, and I kept dropping things on the street, which was quite a headache. No, maybe something had been wrong from this point on?

Anyway, one way or another—I had to get home. I was walking while staring up at the sky when I tripped or got caught on something and fell. Just my luck, this time I fell backwards.

I just had to brush off the stones and dust and get up. I just had to pick up the things I dropped—

But after I fell, my vision blurred, and a ceiling that felt very familiar yet had never been seen before greeted me instead of the night sky. And some person I'd never seen before was there too.
