Su Qingyue, the youngest daughter of the Zhenguo General's Mansion, is sixteen years old. She has some proficiency in music, chess, calligraphy and painting, but she has a certain agility and sassiness because she has practiced boxing and kicking with her father and brother since she was a child. The young general Xiao Jin, who was named "Pingyuan Marquis" due to his military exploits at the age of 19, is the "God of Qing and Cold War" in the hearts of Chang'an girls. However, due to the marriage granted by the emperor, she has to be bound to Su Qingyue, whom she has never met.
