Forever
An older couple, walking under the stars, drew Touya's attention as he looked out of the window. They looked as in love now as if they'd just met, which drew a smile from Touya, as he thought how that would be he and Yukito years from now.
Smiling to himself Touya turned around and looked back at the bed he had just vacated. Yukito had just woken up and caught Touya's eye.
A smile from his snow bunny.
The one thing that would forever make Touya melt.
