"Even if my mind gets fuzzy sometimes, my blood is still clear." I like you, I like you very much. The content is only a few chapters. It is purely the author's emotional work after reading Bungou Stray Dogs. It is full of boring YY. If you don't like it, don't criticize it. Thank you very much. . .
