It's probably a story about Sakunosuke Oda, who was saved in the beast line, and saw the ending of Osamu Dazai, the beast line who was not saved.
However, this article is neither sweet nor abusive, and the author himself does not actually understand the purpose of this article.
The characters may be quite OOC, or the logic may be defective, so please correct me gently.
This article may be a bit boring, so just read it for fun (laughs)
Purpose: redemption
