Welp, look, I've read and listened to lots of stories with this kind of situation alone (I'm talking about a good 100,000 at least), antagonist Waifu turned out to be good, she repented, helped behind the scenes, etc etc etc, so I can predict this kind of stuff fairly well, believe it or not, and it does get boring predicting stuff.
With that being said, for Rachel, there is just something about her that really rubs me the wrong way. Objectively, she's not the worst I've seen, both physically and personality, and hell I even liked some of the worst by plot twists, but something inside of me really doesn't like her and no one can convince me otherwise except for the game dev.
Oh, and mordred, that's a lot of assumptions right there on Rachel while for Pax, your words really gives off trying to guilt tripping into giving Rachel a chance instead of her earning it.
This isn't a flame or toxic towards the dev BTW, just me giving my thoughts as a fan and writer myself
