What me being an almost 50yrs old dude who's never had a long/stable relationship or the analysis I did about Maya?
She does this in every occasion, even early on when you are cuddling together in her bed and she immediately snaps and starts shouting, or when she snaps at Josy when she doesn't immediately dislike the idea of joining the HOTs, etc...
That's part of who she is, the only bit I don't like too much about the VN is that despite her being this kind of person, everyone (well except Quinn & co.) end up on the "we need to save her ass" train, no questions asked, this part is not really beliveable, if that's how you interact with folks... some will be fine some will never be, but I can understand how a story needs a main theme (that's not just MC wants to bang XYZ) to move on.
