You're not wrong. I've said this before but the only difference between Lucas and the MC in this game is that the MC is made to be the hero not by virtue of his actual character but because of his looks, dick size, and status as an older man, and the benefit of the narrative being designed to help him whenever it can. All the girls want to fuck him, everyone here wants to be him, and if Lucas was the main character it would be the exact same except he'd be younger.
People don't have a problem with rape/coercion/grooming in these games unless it's someone else doing it to a girl that they themselves want to fuck. Not that I'm condemning that, I mean I play these games too and they're obviously fantasy, but that's what this is: fantasy. And in fantasy, you're only the good guy because it's you. Your actions don't have consequence, your intentions don't matter, and your transgressions are easily forgiven. That's why we play, but it does not translate to real life.
