Personally really hate the incest so I've come up with this spin when I've played it:
You're in college, you live in a coed dorm (or apartment it doesn't matter). It's the end of the fall semester and you're one of the last people in your dorm to leave for winter break, you're waiting for your ride home but the weather is getting increasingly worse and you might be trapped here at least overnight.
With you in the dorm is:
Jane-your childhood best friend and secret crush who thanks to a scholarship is attending the same school as you and even ended up in the same dorm as you. She's sticking around to talk with Noelle about athletic and academic advice.
Sarah-a carefree and flirty girl who also lives in your dorm and you've shared a few classes with, who like you, is waiting to for a ride home.
Kira-a smart but stuck up RA for your dorm. Since there's only 3 students that have yet to leave, she's the lone remaining RA in your dorm and is waiting for you guys to get picked up.
Noelle-a counselor for the college who's grown fond of Jane, hence why she is willing to stay this late to talk with her.
