I feel very similar. I generally prefer games where the FMC is freely broadening their sexuality rather than blackmailed or coerced into it. Also agree with Ivy being the most interesting for me, followed by Eliot. I do also like the Dean's assistant (can't remember her name at the moment; Madison?) path that's going on if you get out of his blackmail because she seems to genuinely respect that you were able to do that. And the art teacher is certainly new, but potentially interesting too.
And yeah, if the Dean had started with seduction instead of blackmail, he'd probably be pretty close to getting in my Riley's pants (but not before Ivy

). But since he went for blackmail, he gets nothing but Riley's disdain. In fact, I kind of hope Riley can steal his assistant away from him.
