In her previous life, she was killed by her own siblings. In this life, she's sent into the tyrant's harem.
Yun Lin feels that her future is utterly hopeless.
Her reputation as haughty and domineering is already firmly established, and everyone in the palace wants her dead.
Yun Lin: "If I'm going to die so young, why was I reborn?"
Tyrant: "To marry me."
The male lead has a white moonlight, but this is not a substitute romance.

After being reborn, the female lead fights to secure a chance of survival for the people of the Southern Kingdom, willingly allowing herself to be trapped in the harem.
