Shangguan Ya, the eldest daughter of the Marquis of Zhenguo, mistakenly believed in her fiancé Li Ziyang and her concubine Wang Xin in her previous life, and the whole family of the Marquis was executed. She also died with hatred. After she was reborn, she vowed to protect her family and make her enemies pay with blood!
In this life, in the face of Wang Xin's frame-up, she calmly rebelled; in order to prevent her father from getting engaged to Li Ziyang's family, she deliberately told the details of the northwest military situation that only King Nangong Chen of Jing'an knew during the royal hunt. She successfully attracted attention and formed a rift with Nangong Chen. She secretly arranged to collect evidence of Wang Xin's collusion with the boy in the outer courtyard, find Ma Xiang, a scholar from a poor family, help him in the imperial examination, and let him pay attention to the movements of Li Ziyang and his uncle.
At the haircut ceremony, Wang Xin repeated her old tricks. She was well prepared. Not only did she bring out a more gorgeous dress, but she also hinted at Wang Xin's evil intentions, making the ladies from the aristocratic family present suspicious of Wang Xin.
As the revenge plan advances step by step, she and Nangong Chen go from mutual suspicion and testing to gradually developing a vague affection. However, due to Wang Xin's instigation and Li Ziyang's threat, their relationship is full of twists and turns.
At the Mid-Autumn Palace Banquet, she produced evidence of Li Ziyang and Wang Xin's crimes, ruining their reputations. But Nangong Chen's refusal to do anything at the palace banquet made her completely heartbroken.
The leader of the hidden villain's relatives surfaced and sent people to assassinate her and Ma Xiang in order to protect themselves, forcing her to join forces with Nangong Chen again. In the process of solving the final crisis, what kind of life and death test will they experience?
Is it through working together to resolve misunderstandings and gain perfect love? Or should we each be at peace and leave endless reveries behind? Or is it that heaven and man are separated forever, leaving room for regret?
