Wait...what's going on?
The Princess was glad it was a nice day. She intended to go out all day with her ladies, even hitch up their skirts and splash in the water, and have a picnic outside.
It was on the way out that she spotted Namine with Riku. The Prince was busy with receiving and meetings. The Princess insisted that they come along.
Namine spent most of her time with Riku, and the Princess spent most of her time running about with the other ladies. It was only during the picnic they all sat together.
