Ahh, how comforting. Shinji closes is eyes for a moment to just enjoy that soft gesture, exhaling some of that tension he was still holding on to as he does.

"Thank you." They've both been doing their best by each other, that's really all they can ask for.

And, to make his point that he isn't upset with Kai crystal clear, he turns his head, leaning up in order to steal a more proper kiss. He's okay - they're okay.
