So to those who haven't started reading this yet, or those that only read the first or second volume of this series, I must warn you. As I've been very disappointed myself and would have liked to know beforehand, I think others might appreciate knowing this.
The first (Kuroneko Kareshi no Asobikata) and second (Kuroneko Kareshi no Amaekata) volumes of this series are quite good. An interesting setting, good characters, wonderful art, and amazing smut. Thus reading, and knowing there are a lot of other volumes of this series, you'll obviously want to continue reading.
BUT ! Here the problems begin.
Sensei looks like she is relying too much on her art, and the smut. Yes it's beautiful, the sex is fucking hot, BUT with a series this long, without a good plot AND character development, your story ends up an empty shell, beautiful but empty. I'm usually a sucker for good art and smut, and can often forgive the lack of plot, but it dragged on aimlessly for so long here, it even got to the point where the sex annoys me, which is extremely rare. The story's going in circles, with big incoherences. Shingo's and Keiichi's character developement don't make sense, which is irritating.
If the smut was good enough to maintain a certain interest in the series, that'd have been good. But, even if that's nice at first, it ends up feeling like they're more about how it feels good than expressing their love for each other, feels really emotionless, like plain porn. And there's not a wide range of facial expressions, the worst being Keiichi which almost always has the same face.
So if you want to try it, go ahead but you'd better stop at volume one or two, after it's just the same thing repeating endlessly making less and less sense, and being more and more frustrating. Even so, some might still appreciate this to the end.
I'm saying all this because I'm frustrated at how the great potential of this author and story are wasted. There could have been so much more depth and development to this manga, it really is a shame. I strongly hope for Sensei to realize this and offer us better mangas in the future.
