I remember only peeking at the ova to see Kaoru. Other than that I wasn't too interested. Actually, other than the magnificent Kaoru and a few other episodes I really wasn't too impressed with amagami.
Oddly, as much as I love wavy hair on the ladies in anime, I'm not the biggest fan of it in real life. Though some girls pull off the hairstyle and look magnificent.
I haven't been watching it, but it's one of the ongoing series that's on my radar. And for one reason: that curly hair. I've heard good things about it, but I never watch ongoing series. I just keep track of which ones I'm interested in and wait for them to be released on bluray. Ohana's character design was all I needed to make me want to watch it.
