The noble girl is beautiful.

Shen Yourong, as the eldest daughter of the Duke’s household, engraved the word “propriety” into her bones. Her words and actions never faltered. She neither harbored secret affections at a young age, nor engaged in the childhood antics of love-hate relationships.

Moreover, she never encountered any strange encounters while traveling, smoothly embodying the epitome of a noblewoman.
The only hiccup in her otherwise flawless life was her marriage, which didn’t go smoothly. Despite discussing marriage with her cousin, she ended up marrying his uncle, which was quite embarrassing.

The Emperor, advancing in age, favored the fourth prince, Ji Chengyao, for the heir position. The fourth prince’s foster mother, Lady Shu Fei, hinted at a marriage alliance between Shen Yourong’s maternal family, the Duke of Qi’s household, and the fourth prince.
Both overtly and covertly, they suggested that Shen Yourong should befriend the fourth prince.

Ji Zhuo always felt that Shen Yourong, this so-called model noblewoman, was not as genuine as she appeared.

A noblewoman who seemed diligent and earnest shouldn’t be casually snacking on melon seeds while watching the fourth prince flirt with other girls, as her family tried to curry favor with him.

Note: The heroine is a master of fooling people; the hero is a cunning and noble character.
Shen Yourong and Ji Zhuo.
The male lead is not a good person.
