Tsuna blinked at Gokudera. Huh? "Really?" He couldn't see that being possible. Maybe Gokudera would make a swipe at him and miss, or would just be pulled onto the ground along with Tsuna.
"Oh!" he thought of something good! "When we're watching a movie we can...um...like at the campfire." Cuddle, or whatever. "You should put your arm around me, whenever you want." Tsuna was too short to put his arm around Gokudera, otherwise he would offer to do it himself as well. And if he gave him permission, he'd expect it so it wouldn't startle him when it happened.
