She doesn't love the MC, she allowed herself to be raped (could have kicked, screamed, bite, etc... as women who don't want to be raped normally react) all the while going on about her lust for the guy. Then, after the so called rape... she worries about the friendship (seriously, who would consider one a friend who would rape their girl?) and how it would "stress" her relationship.
She goes on to "protest" through typical cuck story fashion, but continues to "allow" hand jobs, blow jobs and continues to get railed by the guy, oh right... "through strong worded protests!" all because... she cares and really loves the MC.
LOL
No woman who loves someone would allow that in such a fashion, nor would she allow it to continue on.
This is similar to the other HC games where it is plot driven to make it "seem" like there is protest, but it is really just pushed in a manner to push the cucking story. This one is more satire, sure... but the story is driven from the perspective of that actual appeal of the FMC to want this. She really wants this, she craves it and seeks it while her protests are just a means for her to rationalize her betrayal and excuse her responsibility concerning her actions.
She has no love for the MC. Love doesn't work like that. Her actions and reasoning are that of a person who cares very little for her so called "love".
This is why these types of stories are a joke, but in this story, it is supposed to be stupid, unreasoned and corny, so at least it gets a pass on that front. There is no logical or "reasoned" means to the characters here though, so I wouldn't even try.
