She is the daughter of a marquis, fleeing an arranged marriage and home because she only wants to see the jianghu from the stories she reads. He is a wandering martial artist with a mysterious past, who only wants to walk alone to the ends of the earth.
She clings to him and insists on going with him. He refuses, but when she is in danger, he catches a blade in his bare hand. Assassins from the Secret Hall, the Grand Preceptor's spies, and the suspicions of imperial power close in around them like a vast net.
She doesn't know that the jade pendant around his neck conceals a secret of the dynasty. He doesn't know that her father holds the last clue to his origins.
When the blizzard comes, for whom will the doors of the charity hall still open?
