It only makes sense to me if Watanuki got laid, which would make total sense. I'm probably wrong, hence the confusion.
It looked like she drank his wine(?) and maybe slipped it to him during the "kiss" moment and said wine being the "down payment," maybe until he recovers the pearl. So maybe have to wait until then to find out what the payment will be?
