"I think you could be a really good dancer with more practice," she encouraged him. "And I think any girl would be really lucky to go with you."
The lack of music didn't matter. Leading him in this simple waltz to no sound was the most fun she'd had all day. She could only imagine how wonderful it would be, the both of them dressed up, him looking more handsome than ever, moving easily to the music while surrounded by other spinning couples. But none of those girls in the other couples would be as happy as she would be with Severus.
And then maybe, when the music slowed down, they would dance very close, and at the right moment, he would lean down and gently kiss her just the way she imagined...
Snapping out of her daydream, she realized how close her lips were to his. It was a lot warmer outside now.
