i was listening to "irony" - the english piano version by lizz robinett, originally made by scop featuring hatsune miku - and felt like a lot of the lyrics and tone fit how i see mostima.
i personally see mostima as high-empathy, low compassion autistic - her outward personality is a combination of having years to study nt social cues as well as performing this sort of... emotional blunting towards herself where she bottles up and doesn't acknowledge a lot of her own emotions let alone others. i get the impression that she's a bit polite with a good-naturedly sneaky streak (nothing malicious) and that she really does care about others - especially exu! it's just that for her properly processing this all let alone forming more intimate attachments with others would be way too much for her to the point of processing all of that would most likely result in her feeling physical pain.
you always showed me so much kindness i don't deserve it, i have failed you too much i think my tiny heart is going to split just leave it be for now
this... this part of the song in particular really feels like mostima's directing it to exusiai. she hates herself for her emotional blunting but she doesn't know any other way to communicate in spite of the fact exusiai does care about her, too, and has been much more open about showing it.
