This whole scene broke me ngl. Not just the yuri but what we heard of the new Akito Matsuda composition sounds so good, and it seems to be another big one (we see the sheet music says Movement 1 at the top). Man really knows how to write yuri ballads.
Yesterday on the timeline I saw people posting a particular screenshot of Kumiko I thought they had zoomed in on and I gotta say...being a fan of this series since high school I've seen a lot of people being Totally Normal About High School Girls, but seeing Ishihara & co. do the same thing sucks!
