It does look cute. But it's yet another series that makes me believe that Japan must be over 99% female. Is it just so impossible to expect a series with more than one male main character anymore >_<
Isn't it for (non-action) stories of any media aimed at 1 specific gender pretty standard to have more/prettier characters of the oposite sex? (since the watcher doesn't want much "competition" from his/her own gender)
Lots of anime seems to be these days: anime type "N" is profitable among "male Japanses otaku" -> more of anime type "N" gets made, since that's financially safe -> at some point there's more of anime type "N" than the "male Japanese otaku" ecosystem can support -> some other hype will mostly replace anime type "N" and the population of anime type "N" will go down to a more sustainable level again.
So you will always have "why is there so much of type 'N'?" booms...
Here, have some reverse-harem: http://www.youtube.com/watch?v=srR1xLzkAVg
to rebalance the anime population at bit.
kind of sad one gets named "reverse" and not just something like "female harem"/"male harem"...)
