Hearing Hayato actually say he was afraid felt strange.
But Ryuutaro knew what he was talking about. The moment he'd woken up in the Dark Nebula he'd felt the same.
When Hayato's hand went down again, Ryuutaro just took it into his.
"I'm not going to", not willingly at least. Ryuutaro didn't want to think about the possibility of them being forcefully separated, each returned to their own world for good.
"...you are my fate after all..."
And everyone knew how Ryuutaro was about fate. It was about the only thing that could keep him chained. In the beginning it had been a bit scary to actually accept the bonds with Hayato, accept to belong somewhere.
But fate had brought him there and it felt just okay to be together instead of on his own.
Finding his own place didn't necessarily mean that he had to have it all to himself. That was something he'd realized back then.
Forcefully keeping himself away and fully independent, even when being with Hayato felt better, would be a cage he'd lock himself into. And plainly just a stupid thing to do.
Ryuutaro was over that now. He'd made his choice and wouldn't let any insecurities appear now.
This was the first time he directly named Hayato as his fate instead of just saying something like 'this'.
