Getting Ayumu's "backstory" and initial push into her interest in space went about what I expected, given her preoccupation with UFOs specifically, but it still is a bit heart-wrenching to hear that she was effectively isolated due to just being who she was even back then.
She bears it so stoically now, but it'd be crushing for a primary schooler to experience that level of loneliness. It did give her the cosmos to latch onto, and that is something worthwhile in terms of pursuing and learning about.
But that inability to tell others about the stuff you find so fascinating...well, it hurts.
Which makes Hina-senpai's introduction into Ayumu's life so wonderfully serendipitous. Even her denseness and one-track(heh)-mindedness aside, Ayumu's life grew so much brighter with her senpai in it. Even if Asuka remains a bit of a sticking point (try as Ayumu might to be friends, or at least friendly, with her), her world's expanded, and I'd argue that she now very much has friends, though one would become much more, hopefully.
Not looking good for the short term, though. Hina not responding could mean anything in that moment, though all her blushing and flustered expressions really do point to her developing real feelings. Asuka must have an inkling as to what's going on, which would explain her text to Hina at the end.
But shooting her own shot is something she should have done ages ago. So it's only natural, and I'd argue fair, that she gets her chance with Hina. Hopefully, everyone can accept whatever outcome results from that confession.
I mostly just worry about what Ayumu will do if Hina rejects her here in this moment. She just let forth the truth about her lack of friends and her awkwardness, and reiterated that she doesn't see Hina as a friend (with the implications being what they are). But I trust the author to tell a good story, and one that will do justice to everyone.
Thanks for the TL as always.
