One day I was walking alone on the way to dinner, thinking that many times, for various reasons, I like to disconnect from my friends around me, and I like to feel like I am alone in a crowd of people, so I got inspiration.
At the same time, the background of this story was adapted from an immature science fiction essay in junior high school that I remembered. It has been a long time since I wrote a book, so this is a familiar yet unfamiliar attempt. I hope readers will like it.
