I don't think Jenny should be a repeat of Roxxy's story either, the thing is if you're giving me different paths in game at least make them matter, if you read her diary she hints that she might be falling for the MC, but even if you choose the dominant path you never really get to explore that side of her. DC always says that he wants the choices you make to have an impact on the game. Jenny's story could've been a perfect example of that, if you chose to be submissive she would stay a bitch towards the mc, but if you chose to be dominant you could've explored her softer side. In her current story no matter what you choose she stays a bitch.
