Ryuutaro untangled from the other two boys as quickly as he possibly good and his first proper action afterwards is crawling away.
Only after that is done, he turned to look at Hayato. With Uri.

So he did it. So he really did it, after all this time. For a moment Ryuutaro was just relieved. Everything needed to turn out right now, there was not a single bit of doubt.
With the relief came a desire to just run over to Hayato, press against him, then put him to bed...

But no. What did he even think? Leaving everybody hanging like this, doing stupid things, making him worry, leaving him basically on his own in this horrible, hateable place?
Suddenly Ryuutaro'd pride didn't allow him to move a single inch towards Hayato. How could he? He was such an idiot sometimes!

... and then there was this part of him which he desperately wanted to ignore. The one who still couldn't believe that this world, this weird, horrible place, was going to be his homeworld.
And who told him Hayato wouldn't do this more often? Tsunayoshi had seemed used to it. And he knew perfectly well how Hayato could be.... how he was most of the time actually.
This was... stupid. And just a bit too much to take.

The different feelings and urges just crashed down on Ryuutaro like he expected the ceiling to do earlier.
He knew, if he did anything now, it'd be stupid.
So Ryuutaro remained where he was, doing nothing at all in a desperate try to seem composed and get himself together already.
