đọc Special A in manga form will give bạn a better understanding than watching the anime adaption alone. bạn will get entertained bởi almost everything in the manga, like its art that's well drawn compared to the anime (although its art is still quite good). bạn will also see deep character development and thêm characters if bạn continue đọc until the very last book.
So please do continue on reading! I'm sure you'll enjoy thêm of it :)
