Sora showcasing some big growth moments over this three-chapter spread.
I quite liked Prez's moment of "stepping up" to meet Miya's own instance of courage. Confessing your feelings, whether you have an inkling of the other party's own perspective, is a selfish move.
But it's important to put that honesty forward as well, both for your own sake and for theirs: there's a measure of respect in trusting them to be honest to you in turn, whatever the answer may be, and holding it all in will only ever end in that eternal pain of "what if?".
And Sora's right. It's absolutely painful, but it ain't "heartbreak", if you are able to pick yourself back up and keep moving forward, continuing to feel. And Miya and Prez care way too much about one another and have too much history for this to shatter things between them permanently.
With Mahiru seemingly now realizing her feelings toward Sora are changing, I believe that makes 4. Yuu being the catalyst in the boardgame scene for "opening Mahiru's eyes" with that talk about proximity and time creating artificial barriers was an interesting parallel to Miya & Prez - for those two, it didn't end well, but that's not any one person's fault, so much as an incompatible type of "love" that each felt for the other.
And I have to wonder if that same discrepancy exists for Sora and Mahiru. We've gotten strong hints that Mahiru was the one that Sora first "fell for", and not Miya all those years before. With that implied foundation, there's every chance that something real might exist between them, that can be built upon, should they act on it (and Sora realize that he "mixed up the sisters" from the get-go).
But that all comes on the heels of a tangled web of feelings - Miya's conflicting emotions regarding Sora and Prez; Prez pining for Sora but feeling like she has to bow out due to her impending graduation; Pilvy with her own quiet declaration to Miya about gunning for Sora; and Sora's own seeming aimlessness in the wake of Miya's rejection.
They're all connected through the years by various means, and they're all growing ever-closer by virtue of the Trialing Committee, and each of them have big hearts and feelings for at least one other person within the group. Narrative-wise, I really couldn't say who might end up "winning the SoraBowl", and at this point and time just saying Poly Ending feels cheap.
But the relationships being the focus, I think the continuous build-up by the author is working out for making a compelling story, whatever the finale may be.
Thanks for your continued TL work on this series.
