Dancing was not Hermione's "thing".
So, when Draco got up from his seat after dinner to put on a record and asked her to dance, she outright refused him.
She hadn't danced since the Yule Ball, traumatized by Viktor's clumsily heavy feet constantly stomping on hers. Dancing, to her, was not enjoyable at all.
Draco wouldn't take no for an answer, though. He took her hand and swiftly pulled her to her feet and into his arms.
Hermione frowned up at him but he leaned down to kiss her softly, smirking as he did.
Breath stolen, Hermione made an exception.
