Fumino wasn't refreshing at all to me this episode. It probably stems from my discussion with Yuki (concerning childhood friends and their unrelenting abuse to the main character for anything they do, ie Sora no Otoshimono) that has me disliking childhood friend types right now. It would be much more refreshing to me if she openly admitted her feelings for the main character instead, and abandoned her "divine punishment". But I guess you can't have a harem without the tsundere.

That being said, I still enjoyed this episode for the (not so surprising) perfect Nozomi, who is also (not so surprising) very comfortable being naked around other people. Nozomi gained the points Fumino lost for me. I'm looking forward to seeing what develops because of their living together (praying that the ending scene does not allude to Fumino being there as well).

The OP is very catchy and refreshing =].
