What's the Name of That Book??? discussion

I've read this book within the last few years, I'm pretty sure it's set in college, all I can remember is the first part of the book, the main girl is leaving a party the next morning, I wanna say shes barely dressed, and she does this fairly often, she goes outside and the main guy is on a motorbike talking to someone she knows, and she stops to talk to them (this is there first meeting) that's pretty much all I can remember, I'm gonna say this is probably a adult book.
Any help would be great, thank you

Possibly

Yes! that's it, thank you

You are welcome.
