The "posthumous child" of the Border Marquis Mansion, in order to keep the title and military power that her father had sacrificed for her life, she was disguised as a man by her mother for twenty years. She thought she could continue her work safely in the frontier, but an imperial edict summoned her to the capital. The emperor wants to grant a marriage? Are all the powerful people in the court trying to get people around her? Joke. She turned her head and stared at the Dali Temple Minister who was famous for being ruthless and not approachable to women. She stopped horses in the street and presented love poems in court, and she vowed to make the city famous as "The Broken Sleeve". With her goal accomplished, she withdrew and returned to the border. Unexpectedly, the cold and noble man chased her to the military camp with red eyes, making things difficult for her at every turn, just to get her to give an explanation. It was promised to be a joke, so why did he take it seriously?
