The Crazy Emperor's Pampered Cousin

[Crazy Emperor & Delicate Little Sister] Double Cleanliness and Exclusive Pampering, So Sweet!
After being reborn into the body, Shen Tinghe opened her eyes to find herself in the most luxurious and extravagant place in the Great Zhao Dynasty.
My grandfather was the only prince of a different surname; my maternal grandmother was a grand princess, a remarkable woman who fought alongside the late emperor to establish the empire; my maternal grandfather held the position of Minister of the Imperial Secretariat, wielding immense power in the central government.
My father, at a young age, firmly established himself as Minister of Personnel, upright and capable; my mother was a noble and powerful princess of the court, with remarkable shrewdness; my elder brother was accomplished in both literature and martial arts, the ideal husband for countless noble ladies in the capital; my younger brother was considerate and adorable.
What's even more enviable is that the late emperor's personally chosen heir, His Highness the Crown Prince, is her fiancé and the future Empress.
A privileged family background, boundless love and pampering from relatives, and a devoted partner to protect her.

Shen Tinghe: "It would be even better if a certain man could interfere less with me."
Xie Yanzhao, a certain man: "Yuan Yuan, be good."

Xie Yanzhao was a born emperor. He was almost supernaturally intelligent and could calculate flawlessly; he was handsome, but also insanely jealous.
He gave all the tenderness and passion of his life to Shen Tinghe without reservation—the girl he held in the palm of his hand, carefully nurturing and shaping her.
Xie Yanzhao was a monarch, a strict teacher, and also a greedy lover.
There are always some reckless scoundrels who covet other men's wives, but he has the patience and the means to erase those eyesores from her world one by one.
