I have not really enjoyed the fairy-tale parts either, but I can see that they're trying to make parallels to the relationship between Rokka and Atsushi. Like how in episode 6 they were tending to an injured bird, like how Rokka used to visit Atsushi in the hospital.
It's a lot of pushing and pulling and indecision, kind of like real life I guess, and I feel like it's trying to be really subtle and careful while building up to something big. I can feel it in the way that I watch it. Like whenever I see Hazuki in the real world, I have to keep switching in my head like "okay.. wait.. this is actually Atsushi speaking through Hazuki, so whatever Atsushi says, Rokka is going to be hearing it from Hazuki, how will this change the way Rokka takes what he says?" And then there's lots questions that keep running through my head like, 'who is doing the right thing?', who is going to 'end up' with who?, will there be a 'happy-fairy-tale' ending? None of which have 'right' answers. =\ I'm really interested to see where this series decides to go. However it turns out, it's going to be a really delicate ride until the end. (pun not intended)
