Hayato pauses in his little bitchfit at Yamamoto to look at Ryuutaro a bit surprised. Yeah... that would mean they're only a few months apart now. Hayato was still a bit older though... it would have been just too odd if Ryuutaro was suddenly older then him.

"Yeah we are, aren't we?" He laughed and rubbed the back of his neck, at first he thought the de-aging would be annoying, he was physically 17 after all... but this made it a bit more bearable,"I guess bein' 15 again ain't so bad then."

Yamamoto looked from Ryuutaro to Gokudera and back again in surprise. Gokudera really DID act different with him. Really different. Like how he would act with Tsuna different.

"How old are you, Fukami-kun?"
