I like the way the blond girl is, how to put it, not an easy tsundere. Like sure, she's sort of this way because she gave up bla bla bla, but her isolation has some real force and runs deep, and you feel like she'd be unique and strange even without that. So when she doesn't get the point of some kind of trivial social interaction that everyone else takes for granted, her strength of personality kind of makes you look at it from a new perspective.
Lots of characters who are superficially like her are just sort of brittle and bitter, but basically waiting desperately for someone to pry open their shell--one or two pushes and their defences crumble. This girl has some solidity to her ramparts. And some distinctive architecture.
Yes. That. Like she's a more genuine rendition of this sort of character than usual. I aprob
