[Returning her kiss, he smiles into it, happy that his bubbly Yoimiya is back and ready to take on what is arguably the most difficult opponent she's faced head on to date. Next to himself, in his opinion of course...but that's not something he wants to dwell on since that almost ended up in tragedy. Instead, he gets to savor a wonderful kiss from the most wonderful woman he's ever met, feeling his heart warm during and after she pulls away.

His gaze is directed downwards however, to the pinky stuck out in front of him. Tartaglia chortles softly, amused to see her keeping up the tradition of making pinky promises with the most powerful men she's ever met.]

Look at you, you're practically Snezhnayan now, pulling out your pinky like that. Alright...

[He hooks his pinky around hers, reciting the nursery rhyme that he grew up with, as part of the ritual of the pinky promise.]

You make a pinky promise, you keep it all your life,
You break a pinky promise, I throw you on the ice.
The cold will kill your pinky that once betrayed your friend,
The frost will freeze your tongue off so you never lie again.

There. It's a promise.

[His eyes shine despite their dullness, staring into her own with a childish amusement. It's so cute that she'll do silly little things like this, but he does expect her to keep her promise to him.]
