Abel tenses a little at the kiss, but he doesn't resist it. When it turns out to be brief and sweet, he blinks at Cain in confusion, surprised by what seems to be an attempt to reassure. Blushing, he stares at Cain, trying to figure out how to answer that.

He's not sure, really, whether they're okay, but he wants to keep trying his best and he's curious about the little gestures of kindness that Cain has shown, even though he's still very wary of the ways Cain has hurt him. Tentatively, he nods, coming down firmly on the side of cooperation.
