I imagine it depends on the choices you make, I've never played the story mode past the first few scenes so I'm not sure if you get branching options or not, but on the Sandbox mode there are a few choices that set you on one path or another. (one peice of advice I'll give you is when you have a date will Vanessa, don't choose the submissive option without saving first, that route is incomplete and can lock you out of other content)
