In that dreamy place at the edge of sleep and wakefulness, Zoro thought Sanji was trying to tell him something. He was sure it was Sanji, even with his eye closed, even without really being aware enough to think about it. Sanji was trying to tell him something, but he couldn't make out the words.
Zoro's snoring interrupted itself, as he nosed against the back of Sanji's neck, blearily trying to make out what it was that Sanji was saying. He listened to it for a few minutes, before becoming clumsily aware that Sanji wasn't actually speaking, just sort of humming to himself in his sleep. He must be having a good dream. ...Mnh. Sanji.
He smeared lazy kisses against the back of Sanji's nape, his still half-numb fingers curling to paw blindly at the blond's chest.
