   Summary

   Sanemi and Giyuu were both royal princes, they had both fallen head over heals for one another. Sanemi writing letters professing his neverending love for Giyuu, until they got married. Serving as Emperor and Male-Empress side by side. Even having a son, Kazuyuki.

   Six years later, things have changed with time. Now Giyuu found himself falling asleep more times than he'd prefer.

   Sanemi deeming other "duties" more worthy of his time.

   As present as he is unfaithful.
   In both his son, and husband's life.
