Here is the context,

2 days ago, me and this model met in the island. I worked as her manager. She doesn't seem to have a boyfriend at the moment. Seeing as she's a model, she must've been hit on by many boys so I thought I'd ask her out in an unique way: I suggested her "Let's take Instagram photos for each other this weekend at the place you haven't been to yet." I suggested the place to be this mountain. She responded me with "Okay if the schedule is empty."

Even if she said okay, I know she would not remind me this like, "So are we going to mountain this weekend?" so I'LL have to ask/remind her of that plan.

If I'd ask her normally like, "Mountain this weekend?", I'd feel an excuse is coming ("I have schedule now sorry") So I figured I need to come up with something clever and funny way to ask her if she's available. Could you help me come up with a witty line for this?
