Du Yushen, the legitimate daughter of a maternal relative with a weak family background, was forced to be betrothed to the nine-year-old second son of Prince Qin's family due to the scandal surrounding her second sister's private affair. She looks docile and harmless, but in reality she is sober and cold, taking every step of the way, just trying to survive in a deep house. Zhao Yi, the eldest son of the Qin Dynasty, was famous in the capital. He had military exploits and was deeply sinister. He despised the absurdity of the power play among the noble families and watched his younger brother's marriage with indifference.
She seems to be flamboyant and informal, but in fact she is deep-minded and calculating every step of the way. When he first entered the palace, he pretended to be extravagant, deliberately telling the truth, and not acting like a lowly and timid person. At the family banquet, he was not afraid of the eyes of others, and spoke frankly and dared to ask about military supplies at the border, breaking the hypocrisy and elegance of the whole hall.
He was Zhao Yi, the eldest son of King Qin who was favored by the Empress Dowager, had great military achievements, was cold and self-possessed, and was a strict observant of etiquette. He hated glitz and publicity the most. Originally it was a helpless marriage chess game to balance the palace and the court. She just wanted to protect herself and get out of the quagmire of the Du family; he originally just wanted to abide by the rules of the palace and protect the safety of his younger brother. However, starting from the confrontation in the archery field and the promise in Guanwuju, the fate of the two people was tightly bound, and the undercurrent of power intrigues, family disputes, and reserve positions followed one after another. She made every move, and he couldn't help it. This encounter that started out as a calculation eventually turned into a fateful entanglement of love.
Purpose: The daughter of a sober family struggles step by step in the power struggle in the house, saves herself and overcomes the situation, and goes from testing and balancing each other to loving each other with the cold and powerful prince. She sticks to her heart, breaks away from the fate of the family, and takes control of her own life and marriage.
