Shen Zhaozhao transmigrates into a book as a supporting female character destined to be used as an experience-point punching bag and eliminated. Having only read the table of contents, she relies on her special cheat ability, the "Gossip Daily," to predict the future and sets her sights on making money and establishing her own household. She saves Prince Xie Linyuan, who is suffering from the Love Emperor Gu, and uses her life-saving favor to demand a reward, walking away with a dragon-bone jade thumb ring. Whenever the full moon arrives, Xie Linyuan suffers unbearable pain as the Gu poison flares up, yet Shen Zhaozhao's touch unexpectedly soothes the Gu worm. But she only wants to turn this into a business, marketing the "right to use Calming Powder" to Xie Linyuan and charging him per use. One is obsessed with money, while the other is arrogant yet secretly devoted. Amid the struggle for the throne and secret rivalries within the household, the two hilariously find their way into each other's hearts.
