You're sure her friends will remember you once they wake up. They’ll be able to tell her all about you.
Or maybe she just might remember on her own. She starts getting flashes of memory of the night before. It’s fuzzy but she can see just enough to know what happened between the two of them.
She was visibly shaken by the sudden flash of memories. She looks up at you, and blushes. She then turns, jumps out of the chair, and bolts out of the room, knocking the chair over in the process.
