Idk if the author themselves researched it, but the process of bookbinding seems to be so well put and detailed it genuinely made me question if theyve ever learned how to bind a book professionally in the ancient ways before they started writing this manga. It even has their own unique designs and ways it feels like im actually looking at another culture thats foreign to ours making a new book.
This shit is so peak and well thought out i genuinely believe this entire world was this author's passion project and everything in their life was all to create this world. Its too detailed for a 40 chapter manga (currently and on going)
