I've watched the anime for this, so I already know the story. And honestly, I think a story about volleyball (or any sport, really) is more effective on a TV screen than on the page...
BUT!
I really love these characters, people. I just do, whether in an anime or manga. Even if some of my favorites weren't on their best behavior in Vol. 1 (I'm looking at you, Tsukki!), I giggled and grinned my way through, and I'm ready to visit them all again soon!
