He was the founding ruler of Northern Wei. Born posthumously and a prince of a fallen kingdom, he endured the hardships of living under another's roof and fulfilled his mission to restore his kingdom. Restoring the kingdom was both his birthright and the sole meaning of his life. Calm and rational, with a deeply calculating mind, he believed that all emotions were tools for manipulating others. He thought he had seen through everything and understood the nature of emotion, yet was in fact deeply caught up in it without realizing. He deceived himself and ignored the voice within, choosing time and again to push her away, only to fall deeper with every step.
She was the legitimate daughter of the Crown Prince of Yan. Having lost her mother as a child, she bore the burden of supporting her younger brother and avenging her family. By chance, she met him, and he chose her. To help her father ascend the throne and her brother seize power, she resolutely married far away and became his queen. This was a great contest between them: they used each other and kept out of each other's affairs, with the only risk being that they might lose their hearts. They were alike, believing themselves cold-hearted and invulnerable, yet in the end they lost their way under the guidance of fate, and all they had pursued throughout their lives came to nothing.
