Face still down, Riku raised an arm in the air, giving Sora a thumbs-up for a second before laying it down again. His back rose and fell with silent shallow breaths. After a moment, he rolled over onto his back, eyes and lips squeezed tight. He looked pained and frustrated. At least Sora wasn't taking advantage of the fact he was down. Leave it to his best friend to be a good sport.
Sora is a good guy.
"I'll deal. But I'm out for now."
