I'm a bibliophile - something that should be obvious to anyone who is using this site. Also, considering that you, too, use Goodreads, then the odds are high that you are also a bibliophile. Well, this series is basically a fan-service series for bibliophiles. Yes, they're talking about manga instead of more conventional books, but the points still stand - this is a manga about books and the people who love them, for people who love books, by someone who loves books.
The writer, Seimu Yoshizaki, understands books, and wants to share his love of books with the reader - and does a fantastic job of doing it over the course of the manga, through good art and great writing. I simply cannot recommend this manga enough.
