At least that statement seems to be enough for Madoka, since she does move in for a hug after he says it. Wrapping her arms around him as far as she can get, letting her head rest against his chest. Maybe it should be uncomfortable, since it's not like she knows him that well yet, but somehow it isn't.

Maybe it's since she's so close to Jiang Cheng, and he's so important to that man as well. Or maybe it's just since he's seemed nothing but nice and gentle whenever she's spoken to him.

So she just remains in that hug for a moment or two before she softly speaks up: ".. I hope this is a good hug.."

Is she worried about whether or not he might like it, even now?

Yes. Yes, she sure is.
