You ask for a hint

Embarrassed and uncomfortable by what just happened, you don't wanna guess anymore, so you ask for some help. "Can you at least give me a hint?"

"A hint? Hmm..." She pretends to think. "It involves you and me. Just us, alone." She looks at you attentively, waiting for you to realize what she means.

The way she phrases it surprises you. Does she actually wanna do what you think? Is she into you? You want to ask her, but you're afraid she will be mad if it's wrong.
