"We must try and be nice to him," Riku added the rose scent to the tub and moved his hand through the water to try and get it mixed in. "We are very... demanding sometimes. Not for things, but that people accept us." And it could be difficult for some people.
Riku dried his hands off and began helping Sora out of his shirt, trying to be good and not put his hands EVERYWHERE that he could. He stopped though, with his hands in the material of the Prince's shirt, when he suggested he talk to the King.
"But..." It wasn't that Riku didn't WANT to ask the King for his lover's hand. He would be honored to do so. He was pleased that Sora might want him to. But... "What if he says no?" If he said no, that was it, wasn't it? If Riku asked, and was given an answer, they didn't have a fall-back.
