Surgical screws do really feel like the sort of think Chokki-senpai would be super into having, and that's before it coming from (and out of) the kouhai she likes.
Hopefully she doesn't continue swallowing her feelings for too much longer. But her being genuinely happy for Shun...well, it's awesome to see. He's putting together his future, tying directly to a past that was both immensely important to him, and one that he thought he'd lost completely.
And she's been a part of him recovering from that loss, and even reclaiming a version of it that he has seen transmuted, and can carry forward with him in new ways that in turn can serve to help others.
Just a wonderful metamorphosis of events and feelings, and an incredible payoff for Shun's character.
"now Chokki just needs to stop screwing herself over and get together with him."
(thanks for the TL work as always.)
