[His own heart is rushing fast just as much, maybe never even really stopped, feeling to him like it's thundering relentlessly in his chest right up against Shiro's palm. He's not sure if it's a result of everything rolling over him at once now, catching up to him, but he suddenly just feels overwhelmed. Selfishly... he doesn't want to let go. The thought of staying here, while Shiro goes and spends the rest of the night outside, that alone is enough to bother him, but he knows how much of it is just as much his own need. It's so self-centered he kind of hates himself for it in that moment.
Still, he doesn't stop. He squeezes Shiro's hand and speaks low and unbearably soft.]
I'll sleep, rest, all of it, so just -- you don't have to go.
