you're forgetting that humans tend to have terrible views of things such as werewolves and vampires as being evil or monsters. also not to mention the bad blood between vamps and wolves as seen in the dinner between us and the count in which he basically calls them dogs. as for the rekindling thing, I doubt it would happen since we have the choice in the game to break things off with Anne. I just don't see her as a recurring character going forward
People frequently, though not always, have negative views of various traits until someone they love gains one of those traits.
It is entirely possibly for Anne, if she has a negative reaction, to come around. MC isn't a "monster" he's her boyfriend.
Our vampire girlfriend doesn't agree with being against werewolves, otherwise she wouldn't be our girlfriend. You know, because we are a wolf. So there'd be no reason for her to not convert Anne, unless of course converting someone counts against her single pregnancy. I can't imagine that being the case because it'd be ridiculous. So yea Vamp GF could convert Anne. And no, Anne wouldn't have any inherent hatred for Vamps any more than we did. Again, we are dating a Vamp.
We have NO CHOICE in breaking up with her or not, simply in HOW we broke up with her. It is my belief that the reason the break up was forced was so people could connect with all the new girls, creating the harem, without (the guilt of) cheating on the first girlfriend. Though I did sleep with the succubus before sending the break up letter, so i'll have to go back and fix that when the next release is out. But yea, I can easily see her coming back
