The flower of sincerity blooms in the cage of political marriage.
When the supervisor and the monitored gradually see each other's sincerity in the maelstrom of intrigues, this marriage that began with calculation becomes the key to subverting the chess game.
On one side is the brave loyalty under the cold moon at the border, and on the other side is the secret of blood feud hidden in the deep palace. The general and the princess form a life-and-death alliance in mutual testing.
From the frosty confrontation on the wedding night to the fight side by side in front of the Xuanwu Gate, they used their marriage as a shield and true love as a blade to fight their way through princeling factional conflicts, foreign conspiracies, and court strife, and finally jointly protect the mountains and rivers they love so much.
