... The anime looks like it has more ecchi scenes than the manga and light novels, but that's probably due to the fact that it's really condensed and seems like they're rushing through the story.
In any case, Chizuru is really insecure and a pathological liar. Though, I like Nozomu for the same reasons I like Nao.
Also, 5pb is doing a game adaption for Kanokon.

With the way things are going, I wouldn't be surprised if "Asobi ni Iku yo!" gets an anime adaption, it got everything else thus far.
