Ye Shuyu is the legitimate daughter of the Prime Minister's household. Her mother died young, her father doesn't love her, and she suffers constant abuse from her father's concubines and her half-sisters.
She thought Jun Linchuan would be the only light in her life. She spent her whole life plotting to clear the way for him to ascend the throne, only to be discarded once she was no longer useful, left with no one by her side.
Jun Linchuan takes the throne, then accuses her and her maternal family of treason. To prove their innocence, not one member of her maternal family survives. She is confined to the Cold Palace, where her half-sister eventually kills her. Only then does Ye Shuyu realize that her half-sister and the concubines have been plotting against her, and even the maid by her side has been working for someone else.
Reborn, Ye Shuyu returns to the age of fourteen. She is still the legitimate daughter of the Prime Minister's household, her relationship with her father has not yet soured, she has not yet dragged her maternal family into the political struggle, and she has not yet met Jun Linchuan.
In this new life, Ye Shuyu wants only to live differently. She will expose the sinister schemes of her half-sister and the concubines, and stay away from Jun Linchuan. What she never expected was that, in both this life and her last, she would be the apple of someone else's eye.
