To learn the truth about the annihilation of her original family "Su", she had to reach an agreement with Shen Qingce, the new top scholar sent by the emperor to "guard" her, who was known for his outrightness and sharp tongue: She would use her superb cooking skills to solve Shen Qingce's "anorexia" and provide clues, and he would use his skills as a counselor to help her navigate the court and investigate old cases. From the initial dislike of each other (he disliked her for being "uninformative and opportunistic", she criticized him for being "acrimonious and ignorant of enjoyment"), the two gradually discovered each other's shining points in the process of jointly facing partisan strife, palace intrigues, and border crises. Su Jinshu uses delicious food to open up joints and uses modern thinking to overcome difficulties repeatedly; Shen Qingce protects her with strategies and clears the fog with wisdom. In the end, they not only found the real culprit who framed the Su family (related to the Queen Mother's family), but also made great contributions to maintaining the stability of the country and promoting the reform of people's livelihood. The feelings that started with transactions, were loyal to talents, and fell into sincerity finally came to fruition amidst the fireworks in the sky and the fragrance in the city.
