[Holding him like this, it'll be clear the moment he shivers, hearing the words again-- no, he's definitely not over it. He knows what it means for Keith to say it at all, to mean it like this, to be able to hear it and return those feelings... He's grateful.]
[He turns his head, nuzzling into his hair. He's done something similar before, almost not aware when he was doing so, but this time he leans into the affection, breathes out softly and kisses first his temple and then the shell of his ear, holding him close.]
Thank you. [... A moment later he starts blushing up to his ears, laughing a little in embarrassment.] Ha, sounds silly to be thanking you.
[But whatever. He means it. He'll never be able to express what this means to him.]
