I also can't tell if it was Yuu smiling and crying near the end there, but I'm guessing it was her mom since the author did their best to hide who it actually was (eyes were closed, the shirt colour wasn't shown and they both look similar). I'm only going with it being her mom since it's like Yuu's face is being hidden and the mom was on the left side of the page and table and she's got tears as she hugs Yuu
I just noticed... Yuu's second glass barrier gets broken when she's hugged, ugh, my heart.
