Five years after dying in the book she transmigrated into, Pei Youci has returned.
In the original story, she was a love-struck, troublemaking supporting character who became the biggest joke in the capital trying to win over the icy young heir.
Then the original heroine appeared and turned her against her uncle, Xiao Wuyan. Pei Youci mistook him for the man who had gotten her entire family executed. Her uncle adored her and was willing to endure the punishment of having his bones scraped clean to save her, but she still ended up pierced by an arrow from the young heir and died full of resentment in a mass grave.
The treacherous minister Xiao Wuyan is peerlessly handsome, cool and ruthless, and powerful enough to dominate the court. In the capital, everyone curses him and fears him as the jade-faced Black Yama. He has no interest in women, yet dotes on his little niece above all else.
When Pei Youci gets into trouble, he cleans up after her. When she falls for someone else, he swallows his feelings and lets her have her way. When she is killed, he completely loses himself to darkness and turns the capital upside down, making the whole city pay for her death!
But then, one day, the precious girl he has longed for day and night returns, and she wears herself out trying to keep him from going astray.
Xiao Wuyan loves having her cling to him like she used to, and loves when she acts tough with him at home. He thinks she's utterly adorable, until his precious girl gets drunk and admits she likes him. Then he can no longer hold back.
The twisted possessiveness buried deep within him for so long is unleashed upon Pei Youci in full force.
Pei Youci: I don't know what happened. It's like he suddenly became a different person. Even having sex in broad daylight is nothing to him. He tries every position under the sun, and keeps me in bed day and night. My back can't take it.
Xiao Wuyan: What's the young heir matter? If he dares treat my precious girl badly, I'll kill them all! Overthrowing the throne is nothing. As long as she's happy, I don't care.
