On the eve of her wedding, Qin Yan was kidnapped by the Qin family and sent to the palace in the capital overnight, where she became the sleeping substitute for her eldest sister Qin Xin.
Qin Yan was a low-ranking female official that everyone looked down upon during the day, but at night she became the young emperor's favorite.
Qin Xin relies on her to win the favor of the Sixth Palace at night and is arrogant.
Qin Yan, who had long been numb, was deprived of everything until she became pregnant with the emperor's child.
Driven by maternal love, she awakened, and she began to work on how to replace Qin Xin and become the winner in the harem.
Xiao Heng has always felt that Qin Xin, whom he has watched grow up since childhood, is the woman who truly suits his heart.
But suddenly on the night when the imperial commander came back from the expedition, he heard the sound of the woman beside him crying in her dream.
As a noble concubine of the Sixth Palace, she was the most noble woman in the world besides the queen, but she wanted to die.
Xiao Heng was shocked. He felt that his love for Qin Xin had already exceeded that of all the women in the harem. Why did she still want to commit suicide?
So, he quietly began to investigate everything about Qin Xin, including the concubine she suddenly brought to the palace.
Soon, he discovered the truth. It turned out that the ecstatic beauty he was fascinated by every night was actually the inconspicuous female officer during the day.
Xiao Heng suddenly felt very interesting. He would not forgive Sister Qin Xin, so he started a cat and mouse game.
He originally thought that after Qin Yan gave birth to his first child, the two sisters would go to hell together, but later he discovered that he could no longer live without that beautiful figure at night.
So, Xiao Heng began to carefully plan to personally send Qin Yan to the highest position in the harem.
