Su Jin'er entered the palace for the first time, but accidentally had a heart-to-heart talk with the emperor. In the end, because she couldn't bear to see the emperor's lonely eyes, she made a promise that she could not take back in her life.
The agreement and the exchange of conditions were just to fulfill the dream of an emperor.

In the end, Jin'er grew from an ignorant girl to a mother of a country praised by everyone in the world, but she also lost the most important person in her life.
