This is the serialized version of the short story with the same title that I previously posted.

The fourth chapter contains the same content as the short story.

July 2019: Published as a book by Earth Star Novel. We appreciate your support.

May 2020: Volume 1 of the manga adaptation was released. We appreciate your support.

January 2024: I am making partial deletions as I will be generally revising the story, with the exception of some parts (primarily those that have been published as a book and adapted into a comic).
