Theory: The system is trying to force the heroine towards one of the LIs. She's got her own system popups that she's actively avoiding in order to chase Evie. That's why she got possessed the first chapter: she was being punished.
i can see this happening.. or this was originally the case but somehow, in the intervening time between Ch1 and Ch2, the heroine managed to break her system somehow which now pushes her to get bullied by Evie
