This story is set during the Tang Dynasty, spanning the reign of Emperor Gaozong, Wu Zetian, Emperor Zhongzong, and Emperor Ruizong. Princess Taiping was born to Empress Wu and Emperor Gaozong of Tang. She was pampered and doted on by her mother, and free from the struggles that her brothers face. The innocent princess fell in love with Xue Shao, a commoner she met outside of the palace. She was determined to marry him, and Empress Wu allowed for their marriage. Xue Shao already had a wife and refused to marry Princess Taiping. Empress Wu then murdered Xue Shao's wife so the daughter she dearly loved would find happiness. Xue Shao was saddened and committed suicide in front of Princess Taiping. That was the moment when Princess Taiping realized the horror of her mother's power. After her mother became the Emperor, Princess Taiping withheld great power regarding politics. The princess decided to be rebellious and remarried to Wu Sansi's cousin, Wu Youji. Wu Youji was kind and harmless, but the princess wasn't content with her life. Wu Youji was known for conducting a special kind of medicine and gained the favor of Wu Zetian. This medicine also led him to have an affair by mistake. He committed suicide out of guilt towards Princess Taiping. After two failed marriages, the widowed princess was disillusioned with her identity. One day, she met a man who looked exactly like Xue Shao. His name was Zhang Yizhi, and he would change her life. She fell in love with him, but Wu Zetian saw through Zhang Yizhi's motives. He was a womanizer that took advantage of others to benefit himself and Wu Zetian forced him to leave Princess Taiping. Zhang Yizhi became Wu Zetian's lover, to the horror of the princess. Once again, she felt lonely and depressed longing for love. Eventually, Wu Zetian loses her power after a decade of politics struggles. Before she dies, she resolves her misunderstandings with her daughter, and the two embrace each other one last time. After her mother's death, Princess Taiping becomes ambitious about politics. This leads to conflicts with her sister-in-law, Lady Wei. Lady Wei wanted to be the next Wu Zetian and she was trusted and loved by her husband, Emperor Zhongzong. This trust led to his demise, as he was poisoned by his daughter, Princess Anle. Princess Anle and her mother Lady Wei were corrupt and Princess Taiping couldn't bear witnessing the destruction of her family. Princess Taiping overthrows Lady Wei and Princess Anle, and returns power to her brother. Her life is peaceful, until Xue Shao's son Xue Chongjian suggests her to take the throne.

However, the plan is revealed to Li Longji, Li Dan's son and the nephew of Princess Taiping. She tries to assassinate him, but he survives. Li Longji reveals that his feelings for her are greater than an aunt-nephew relationship. He loved her for twenty years, but Princess Taiping only loved him as an nephew.
