In the first year of the Jingshang Kingdom, two princes were born at the same time. The establishment of the eldest son as the crown prince and the establishment of the direct descendant as the crown prince became important political matters discussed at that time. With the death of the eldest prince's mother, Concubine Liu Mengru, this topic became taboo in the palace. Fifteen years later, the emperor died, the second prince ascended the throne, and the queen mother took power. In the name of filial piety, she forced the eldest prince to stay in the imperial mausoleum all year round and was not allowed to return to the capital.
While guarding the mausoleum, he rescued the Prime Minister's eldest daughter Xia Qiongyue and made a lifelong wish, but was forcibly separated by the Queen Mother. In order to consolidate her power, she arranged to marry Xia Qiongyue to the new emperor. He also gave Xia Zhiyao, the second daughter of the prime minister, to Yu Shangyi for restraint.
The eldest prince felt sad and angry, but he had to accept it. At this time, Liu Mengru's wet nurse found the eldest prince with a suicide note. From then on, the eldest prince learned that he was not the queen's biological child, and also knew the truth about the deaths of his biological mother and maternal grandparents. He vowed to seize the throne and realize his mother's long-cherished wish. In the process of seizing the throne, he secretly fell in love with Xia Zhiyao.
Intention: friction with the supreme power, and the feelings that bind marriage
