Is this a metaphor for not having romantic feelings towards a friend?
Or maybe it is a demon pretending to be her?
Maybe a twisted existence that has always been her?
A spatial distortion, that confuses light reaching our eyes?
Could their reality be consumed by Eternal Decay?
Is this just a trickery of gods, their way to make fun of puny human erotism desires by melting her shapes into grotesque forms?
Or was it a cognitive virus, that made it's way deep into wiring's of MC's cortex, inducing changes to world both inside and even partially outside of his head?
Either way, it's cute.
