[So acutely aware of every little shift of his hands, his touch, especially in how he's shaking -- he's noticing it far more than the way he trembles too nearly everywhere that Shiro touches. Keith's hands brush up his back and to his shoulders to squeeze gently at either one in an effort to soothe him just as much, to keep that contact.
When Shiro cups his cheek, he practically sinks into it, tilting his head to his hand. He can't help the stuttering way his breath catches before letting his lips press into the gentle pressure of his thumb - then tipping lower to kiss his wrist, the center of his palm, listening and not trusting himself to speak right away, so opting to do this instead. Even his lowered gaze is because he knows his eyes are barely a step away from tears.]
For me too. [He finds his voice and it carries an equally wobbly rasp, speaking into Shiro's palm.] When we met, that moment... really changed everything. For us both, I know.
I think - I could have searched the whole universe and never found anything close to this with you.
