Can't really say anything substantive with just the first half like this, especially without the knowledge of what she wrote down on her Tanzaku slip.
Obviously it's gonna be "gloom & doom" after she just up and left Sorata behind, with him being largely absent from the chapter (even when physically present).
We do get another dose of Ayano's personality, and once again his general demeanor and way of speaking make him rather off-putting when compared to the rest of the cast (and now the two side-friends see it to varying degrees). But most of what's currently ongoing hinges on whether Sorata & Miyuki actually attempt a dialogue, and while I expect it to happen in order to not let the narrative just.....stall completely, can't really go into things much more at this time.
Though having said that - I will say that Mary's line about thinking it obvious that Miyuki would go onto college struck me as odd, especially her line about Miyuki being "particular and super curious". Mostly because if I were to classify Miyuki as "super curious", it's mostly out of a sense of being in a place so unlike where she grew up, rather than an innate characteristic of her personality.
That, and it doesn't necessarily seem like something that would translate into "well that means higher education's obviously in your future", but it does call into question whether Miyuki really sees herself as someone who could have aspirations in her life. She has always been good at stuff, but has never been really all that invested in those things--and her inability to really mesh with her peers because of her reserved personality didn't help matters. Sorata came along and started shifting that side of her, and she went so far as to follow him back to Tokyo (whether of her own volition *or for her grandfather), so she's definitely not the same person as before.
The issue from there being that she needs to truly square what she wants, and not sit here basing herself and her future on what those around her expect. Miyuki needs to self-actualize, basically, and not listen to Ayano, or Sorata, or her grandfather, or anyone else.
So I had more to say than I thought I did, I guess.
But, thanks for the TL work.
Also--you initially translated the second speech bubble on pg. 16 as "hmm." instead of "well," - as it's a flashback bit from 20.2.
The "hmm." made more sense as a response from Miyuki to Sorata's line that recalls Ayano's sentiments about Miyuki "limiting herself" just to go to a school that Sorata could manage to attend, but I figured I'd point it out because the change-up sorta calls into question which speech bubble belongs/belonged to which character.
