The guy who started translating this here (also, my first comment, yay!). I know that the caption with the arrow pointing at Yuuko says something about the possibility of an illicit affair, but I can't make out the last two or three characters. About the lower right, I can make out all the words with some certainty, but I just can't make heads or tails of that sentence (or even figure out how many sentences are supposed to be there). It says something about them putting on a "not getting along" performance so good everyone talks about them being like cats and dogs, then describes them in brackets as "officially approved yuri", and ends with saying, "but they went to the festival together..."
Pretty much. It's mostly this girl like this girl who respects this girl who likes her who likes that other girl because they were friends and this girl who hates this girl for reasons but actually likes this girl, etc. etc. Gotta watch the show to understand.
I think there's only one canon couple in the show and they're adorable. Coincidentally they're also the only couple that's a male and female relationship.
Finally figured out how to translate it all, 10 months later..
Kaori senpai...Typical yuri girl looking up to the MadonnaHibike! Euphonium's 2nd year fighting couple is seethingThey act like they're at loggerheads to the extent that others end up saying they "get along like a cat and a dog" (authorized yuri)There they are, at it againYet they go to the festival together...The possibility of an illicit affair is microscopic...
