I really hope this moves towards accepting the flaws and differences in ourselves and other people while rejecting the pedestals we build for them... Ito has her own messed up headspace but it doesn't excuse her own shitty behavior.
I think the story realizes this, from my understanding of things Ito internally realizes that she's doing the same thing Mina did to her, stringing along a girl who values her opinion over their own needs but because of her own personal trauma she's finding it hard to listen that voice in the back of her head that's telling her "You're being real fucking shitty right now, come on." It doesn't excuse what she's doing but hopefully the story fully moves in that direction.
