I... take it he doesn't dance often at events? [Maybe he only danced with Nunnally at events to make sure she at least had a good time. And maybe Milly because he was guilt-tripped into doing it. Maybe.]

[Well, he had at least two official dance partners at that event, despite her lack of knowledge of any of the steps involved in that style of dancing.]

[Still felt awkward though. Though at the mention of secret agreements and marriage, of all things, it at least brought some color to her otherwise pale face.]

I'm... not the marrying type. Not in this kind of world, anyway. I'm not even that good at making any sort of agreements or deals like that. [Nah, she's too soft-hearted to even attempt something that devious.]
