Help finding a story

I am looking for a one-shot yaoi story. The story is set in feudal Japan and is about two brothers. The main focus is the little brother who is bought by a patron. He looks out at the snow and remembers the last time he saw his older brother. His older brother snuck into his room after being chased by guards and wounded. The older brother seduces him and then disappears. The older brother is never seen again and everytime it snows the younger brother waits to see him again. I hope someone can help.
