Yeah. [It's true, he does; he's frowning again, because if they both fall asleep, they have no way of knowing if they remain in contact and if Dou is alright or not, and the thought of sleeping for what could be hours while Dou is completely catatonic scares him more than he wants to admit.]
[Sighs, grabbing one of Dou's hands with one quick movement, dragging him close with his arm over him, holding tight to his other hand with his, settling over that arm so that his back is pressed against Dou's]
Don't say a word. [His voice is warning, tight and controlled, covering up his embarrassment-- but he knows this way at least, you can hold on to him, and it's less likely for him to be rolling away from you. So he'll endure this, just this once.]
