Unfortunately for Kai, Ryoji is very not keen on leaving Kai to this fate- even if he believed Kai was alright with it, which he doesn't, Ryoji isn't. He feels like something very precious is being stolen from him. And dragons don't do well with precious things being stolen.

"That's not really an answer..." he murmurs, and reaches up with one of his hands to touch Kai's cheek. He doesn't know what else to say, if Kai won't talk to them, than-- "Please don't do this."
