The Legitimate Daughter Becomes Empress: Reborn into a Game of Strategy

I am the empress, yet I am the least favored woman in the imperial harem.

The emperor has favored the Noble Consort alone for ten years and has never once set foot in my chambers.

On the night the Noble Consort goes into labor, a fire suddenly breaks out in the palace, and the emperor rushes to her chambers first.

I quietly drink the poisoned wine and see in the Book of Life and Death that I don't have long to live.

The next day, I discover that I have been reborn at fifteen.

And the younger sister who caused me to enter the palace and stole the emperor from me now sweetly calls me "Sister."
