The background of this article is seventh grade, which is quite different from the plot of the original work.
The inspiration came from the novel of the same name by Keigo Higashino that I read a year ago. When I was watching the movie version a few days ago, I suddenly felt itchy and then... I borrowed some ideas from the original work, hoping not to discredit Higashino's work.
Originally I wanted to fill in and modify the ending, but then I gave up_(:з∠)_This article ends here, thank you for your support.
