This is one of those mangas that I'm ashamed to admit I enjoyed. I myself am truly surprised I didn't hate it since it has basically all the features I hate put together.
First of all it's true what they say, Ayase is too much of a girl for this to be proper yaoi. And I love a manly uke, not bara but a pretty-boyish type of masculinity. Ayase on the other hand is the girliest uke in the history of yaoi. Not only that, he looks like a child so reading the sex scenes really feels like shota, no more like lolicon...
On top of that Kanou is like this super seme; five times bigger, twice as tall, stronger, filthy rich (whereas Ayase is completely broke), practically invincible, super masculine playboy etc etc. I've never read a yaoi where the distinction between the uke and seme was this huge and there are lots that use the feminine uke/masculine seme stereotypes. It was pretty disturbing.
The other major issue is of course the fact that Kanou is a serial rapist. Now, I've read (and loved) Koisuru Boukun and heard similar accusations against Morinaga, but in that manga the uke was perfectly capable of protecting his own hide. Here however, as mentioned before, not only does Kanou practically own Ayase who's piss poor, but he's much bigger, stronger and a whole lot more violent. Poor Ayase! (in a lot of ways...)
Having said all that, I did read all the chapters scanlated so far. Why? Because it was entertaining. I may have been disgusted at it and disgusted at myself for reading it but from beginning till the end I was still thoroughly entertained... I've been trying to figure out what the appeal was since it's not like the plot was that superb either... Initially I think it was just because it's quite funny. The whole thing with the small animal owning guide for example was hilarious. It's more like the story's got great comedic value or maybe shock value or something... Anyway, the trick is not to look for anything too deep or meaningful in this manga cos you won't find it.
It's lowbrow but it'll keep you occupied if you've got time to kill. I don't regret reading it and I suggest you give it a try. You'll quickly find whether you'll hate it or like it...
