She is an orphan girl stained with blood, hiding her name among the refugees; he is the sick and weak prince of the feudal lord, trapped in a dangerous city in the web of intrigues.
When the flame of revenge collides with the ideal of salvation, two broken souls meet at the decadent border.
She used the lost art of war as a blade to pierce the fog of conspiracy shrouding her home and country; he used the isolated city as a chess piece to navigate the chess game of troubled times surrounded by tigers and wolves.
From the sharp knives of mutual testing to the back-to-back trusting people, they tempered their trust in betrayal and flames of war.
When the mountains and rivers were shattered, how did two sober people carry up the collapsing sky with their humble bodies?
See how the orphan girl uses the rivers and lakes as her camp, uses the art of war as her sword, and plays against fate. Finally, in the bloody chaos, she walks on the path of nirvana from an avenger to a guardian.
