Oh yeah if anybody here can read japanese there's blog for kyoani production staff where they comment about the episode they're working on.
One of the comment is the art director's musing on episode 8 that she wanted to watch that particular scene over and over again, because it was so beautiful. (and imo that's also the highest point of this whole series, the music score is so fucking on point in that scene)
Also it seems the staff also like kumiko and reina pairing and well aware of what they're doing in the anime. My guess is that they can't do anything about the original material and they have to follow it (remember shirobako, original author is the god)
The raws are out. In Korean. And of course, I only spent my life trying to learn Japanese. Why am I screaming to the top of my voice right now? I mean, this is Citrus, I might just end up being deceived once again. But God, this thing is a drug, and I WANT IT freaking badly!
