"Yes, winter," Riku agreed. "We can dance together at Yule," publicly, as fiancees. In love. "Sit before the fire when its cold, wrapped in one large blanket for two." Very romantic.
"What," Riku paused and then tried again, "What is the custom, in Balamb, when two people become enfianceed? In Estar, there is an exchange of rings. In Trabia, there is not. There is a gift given to the woman's family instead, in exchange for losing her labor and help in the house. What do they do in Balamb?" Estar was once part of Balamb, perhaps they shared that tradition?
Riku was thinking about the Spring that he and Sora had already shared together. The Spring Festival, dancing in the sun and flowers.
Then, then Sora pulled him down, and whispered to him, making a shiver run all the way down Riku's spine and his eyes slide closed. "Yes," Riku murmured, wetting his lips, "I am looking forward to it," he whispered back. He paused a moment, and then snuck his hand just ever so slightly up the front of Sora's shirt and vest, careful to keep their bodies so that the guards couldn't see. "I think about it constantly."
