I get that they're love interests and it isn't really about them, but for a game with revenge as a theme I'd hope that characters like Mai and Ayumi would see at least a little comeuppance. I know them being "complex" is intentional but that can remain true and they can face consequences. When characters betray and continue to betray, it's a bit unsatisfying when it's treated like this, even if it makes sense in context. Good dick and getting them away from Kenta are rewards themselves.
I realize it's not finished and this could be premature, I'm just thinking out loud.
