To help the villainess Duan Rongrong survive and reform the obsessive male supporting character, and to keep the transmigration-into-a-book world from collapsing, the Space-Time Administration gave her a dream-visit golden finger.
Duan Rongrong promptly chose to visit all the princes in their dreams: before the old emperor died, he would hold the hand of his only niece, the daughter of his younger sister, and ask which cousin she thought most highly of.
She figured that with seven years left before her uncle the emperor's death, whichever prince governed in his stead, she would enjoy a place at the top of the food chain and be able to finish her mission and go home early.
She never imagined the old emperor would leave a prince of a different surname to govern. With nothing to do, the princes fixed their greedy eyes on Duan Rongrong.
"Cousin, marry me!"
Even more despairing, in the dead of night, the obsessive prince of a different surname, who had become darker the more she tried to reform him, appeared in her bedroom with a faint smile. "Which one of your nephews do you want to marry?"
