NGL.... that's kinda shit writing and just retarded.
Why would you establish these girls as cheaters... and then have them end up with MC (of the manga, not the game).
Like.... how are the readers supposed to go "Nice" when they know they're cheaters. It's just the MC of the manga that they'll eventually betray, not the MC of the game.
Since while the scenario/events have changed, it isn't like their personalities or traits have.
Especially nothing big enough to ingrain into them a hated for cheating and being disloyal that they'd never do it.
All that aside, it's just weird as well... Even if they legit aren't cheaters, and have little to no relation to their game counterpart... MC still knows that story, and sees them as LI's of Leon, it's just weird, and would feel wrong (especially since he hated them going with the dude he is now so much). Where as characters that never appeared, free real-estate.
Although... What should i expect from such gimmicky writing.
Cheers for saving me time though, now i know not to read this one. (would've read, if he didn't end up with any of the games cheating heroines).
