Mei Lingyue, the legitimate daughter of the Shangshu Mansion, forced her brother-in-law, the Marquis of Jin'an, to marry her. The two supported each other on the Monan grassland and lived happily for three years.
Unexpectedly, Ji Heng always kept the princess who grew up together in his heart until the princess who followed him after he made great achievements revealed the truth.
Lingyue insisted on letting go of the past, but Ji Heng, who kept compromising with the emperor and the princess, never let go.
With the help of others, she was finally able to escape to Jiangnan, start a new life, and die holding hands with her husband who loved her deeply and had been waiting for her to respond to her love.
