Well, as long as the Prince KNEW that Roxas knew... it couldn't be too bad.
"Only if you will, Sora." He really needed to give himself more credit. "You are an incredibly handsome man." Plain, ha!
"If you wish for me to dance with others, then I will. I will make you proud to have chosen me, Sora." Not just for love, but for his social abilities too. "I promise to try and leave all hearts intact," Riku promised with a grin, "I have already won the heart I want anyway."
So he was smiling when he finally made it over to the Princess and handed her brother's hand off to her with a genle kind of tenderness. "I would never disappoint fair lady," he promised, "Please take good care of him for me?"
