Just discovered this yesterday and caught up! I like it. Some small thoughts:
It might be just be based on contrast, but the new earrings look like Minamo's eye color, which is so perfect.
Obviously it feels like they like each other, we've had a bunch of badumps from Minamo which is the manga equivalent a big arrow pointing to feelings, but I do think it's interesting that Yurika has spent this entire time denying that she likes Minamo to everyone that knows she's gay. I don't know that it is any more significant than Yurika doesn't expect Minamo to be anything but straight and doesn't want to make her uncomfortable, but even with this pretty much confession, I think Yurika might still be hesitant to believe in something again. I hope I'm wrong, but I imagine there will be more aaaangst in the future as they realize their feelings and can actually name them out loud.
Also, with the way the story has been going so far, no way Yurika and/or Minamo isn't outed in some way at school.
