And Ryuutaro just listened to Hayato's rambling, closing his eyes. It was easy to see that there was no coherent conversation possible anymore, so he might as well enjoy the pure cute, tired idiocy of this.
The last phrases however get Ryuutaro to open his eyes again, only shortly as he let them run through his head again. He smiled.
"Sleep...", he whispered, not loud enough for Hayato to properly hear him in a state like this, "...you need it."

The rest of their lives, huh? Ryuutaro wondered what they would be like... in ten years... in fifteen years... Even for him it was hard to imagine. He didn't even know what this world would be like, having been stuck in this place all of the time... He'd been to lots of places where beyblading was unknown, but would this be the same?
He felt himself getting tired as well from all this thinking and the warm body close to him... Maybe some sleep wasn't so bad after all...
