Never have I ever watched a show wherein I would actually end up loving all the characters. Seriously! I started out liking Sugawara only because, let's face it, he's an angel. Then my soft spot for meganes started kick in and Tsukki stole my heart. Then gaaaahd Nishinoya was just too adorable, then damn Kuro is such a sexy beast, Bokuto is my baby, Akaashi is too beautiful, Oikawa is developing, Iwaizumi is my ace, Papa Daichi, Jesus Asahi, Hinata my little ball of Sunshine, Kageyama you adorable blueberry, Yamaguchi must be protected,I ship Yachi with Yamaguchi, and the list goes oooooon...
I'd also rate the story A for all it's elements (not really an A+ since it focuses too much on V-ball. TOO much)
The character growths of these characters are killing me and you really can't hate one characters.
