God, he really needed Tsuna's allowance for this? Ryuutaro nearly rolled his eyes, but then he figured he really had to learn to deal with this... it didn't make it better one did, but this was probably a thing too major than to have Hayato change it. Grah.
But he was in a forgiving mood, so he let the thought go after a moment.

"I must admit, I'm really curious now. But then again, I suppose so are you?"
It was ten years in the future after all. And Hayato was less used to seeing the future than Ryuutaro was. Granted this was completely different. A too far-away future... and actually being in it.
