There's a certain distance about the storytelling, similar as well to Shimura Takako.
Yeah, the cover made me think it was an Aoi Hana doujin as well. I really dug this, makes me wonder what Shimura porn would look like nowadays.
Anyway, I found this excellent. If you don't give your undivided attention I do see how it could be confusing, but I didn't find that to be the case personally.
More original yuri is always good, anyway.
