While you can rescue Whitney, they're still sent off to a sex dungeon for who knows how long to be put in a miserable state. And with Kylar, they're taken by the police, and we know how suspect the police are in this town, treating prisoners more like toys and whatnot.
Meanwhile, missing class does have punishments, both short-term in the form of Leighton and long-term in the form of school events. As with a high delinquency, the events where classmates try and blame things on you the teachers will actually believe them, serving to give you a punishment.(Edit: Forgot to mention that missing classes also lowers your subject scores, which in turn makes your character weaker with time.) And especially seeing the kinds of things that can happen to Robin, this game can get rather dark at times, so "along the lines of what we already have in the game" could mean some pretty nasty stuff, in my opinion.
Now, I'm by no means trying to say "You're wrong for wanting this!", I just don't like what I personally see from how I'm interpreting it, y'know?
