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