This article is my second article. The first article has already "sacrificed a heroic sacrifice". The first article is about fandom plus time travel. I was lost in the virtual world I had constructed. I got fed up, so I changed my ID and planned to start over. This article is what I really want to write, and I have a desire to talk about it. It is not a time-travel novel, nor a fanfic. The background is in the real world, and the protagonist is "I". The prototype of the protagonist is myself. The protagonist is my slightly idealized image of myself. I have no choice but to add some imaginative elements to it. The theme of the story is youth, which is how we interpret ourselves vividly.
