Yeah, it probably shouldn't matter too much in the long term, since I'm gonna try to avoid bogging things down with long classroom scenes, but who's in who's class does lend some opportunities for classic shoujo moments on the side, like the traditional Person A asking for Person B who's in another class and causing the whole "Are they dating?" rumors to fly around. I guess it would make a difference if we do things like a sports festival or cultural festival arc, though, since that would determine who's on who's team or who's running what events, respectively.
