Ryuutaro looked up at Shamal, hating the fact that he could sit up at all, because well... Hayato was kind of clinging to him. So the compromising position would have to do.
"It's Fukami Ryuutaro" -and very certainly not 'kiddo'.
If he had to ask this question that probably meant Tsuna hadn't explained things to him. Did that mean Ryuutaro'd have to start the explanation all over again?
