Long lost baby brother
Riku had managed to put Le Juillet out of his mind MOSTLY... mostly. He had to focus on his lesson enough that he didn't think about him until after his lesson was over. He wanted to see Namine, but, knowing that she's seen Le Juillet, he didn't want to talk to her. He didn't want to expect anything and be disappointed.
So really, curling up with his cat in his room and trying to read quietly was his best option. And then, when that got boring, he went and visited with the horses. That was a nice work out, and by the time he was done, Orion practically reflected light.
Then he went back to his room and took an early bath so that he wouldn't smell like horses, and jumped his Prince when he came back, play wrestling with him on the floor until he was absolutely exhausted. The Prince was such a good sport.
As dinner got closer, Riku helped the Prince dress for the occasion and dressed himself and went with him to dinner.
"Where are we meeting him?" Riku asked quietly over dinner. Le Juillet. He just assumed the Prince had arranged all that.
