It isn't that he doesn't want to kiss her. He does. He wants to kiss her all the time. But he doesn't want her to think that he's just kissing her just because he wants to be free of the mistletoe - which he does want, but not enough to compromise the other thing.

He pauses, before taking another step in towards her and leaning in to brush a kiss against her cheek softly. He lets it linger longer than he probably should, and there's still emotion there - it's just enough for the seal of the mistletoe to break.

He pauses, before taking a step back with a small smile. "Looks like it worked."
