A few notes on the content of the article: (Be sure to read it!)
The first point is that the setting of this article is similar to the original work regarding Dino. As for Kyoya, here he is just an ordinary high school student, a disciplinary committee member with an awkward personality, and no background in politics, so the contrast with the original work may be greater - metaphorically speaking, his rights in school, his tolerance for group gatherings (because he lives in a dormitory), etc. If you can't accept it, reading the article will be more difficult...
The second point is about corpses. Personally, I like 69 very much, second only to Dino and Kyoya, so he is better in my novels, which can also be seen from "Partridge Sky". In this article, Tsumugi is Kyouya's brother (the details will be explained in the article), and the relationship between the two people is that of a tangled rival and a friend. 69 And 27 in the article, well, I guess they are a rather tangled pair.
The third point is that in this article, bl's cp is only DH, and people in 80, 59, 27, 69, etc. May all have girlfriends... Then, in the setting, 80, 69, 18, and Yuhei are three years old, and 27, 59, Kyoko, and Koharu are second-year students.
The fourth point, if the above is acceptable, please continue reading the article.
