Ryuutaro twitched as Hayato said his own thoughts out loud just so easily. But then he figured that it wasn't all surprising that Hayato knew it... It was so obvious.
Ryuutaro didn't even want to hate this world. He knew that there was more to it than this hideout, this cruelty... but in his mind these few aspects he knew always just added up, the fact that this world almost killed Hayato again, and he couldn't do anything but hate. Hate in a very childish way, but still hate.

Ryuutaro listened on to Hayato voicing his feelings and what he heard didn't make him angry anymore. He'd do anything... Ryuutaro nuzzled his face in Hayato's chest, over time he'd become almost immune to finding dirt on Hayato disgusting- but his voice still came out almost clear.
"I know.... And I... I'm trying, too, you know? It's not enough for your world yet.... but someday it will be." "
Ryuutaro had been working to get on top of his world, he'd been working a lot for it back then, and he'd be able to do it, too, in this world. He'd get to the top. With something.
Taking shouldering all of my fate as well as yours is an impossible task."
