She was once the empress of the future world, a queen revered by all, yet she fell in love with the man in a book. For his sake, she was willing to give up her throne and the world she lived in, traveling alone to his world.
He was the sole heir to the throne, with ideals and a future of his own. Yet the moment he first saw her, she tricked him into becoming her future husband. She even threatened him with her life to make him learn the martial arts he least wanted to study. But as time passed, he fell in love with her, until he was utterly unable to extricate himself.
They grew up together as childhood friends. He returned to court while she remained in the martial world, building up her own power to prepare for the new age of prosperity she would later help him establish.
She returned from the martial world for his sake, rooting out corrupt officials, seizing power, and battling the court ministers... all to build a brand-new, prosperous dynasty for him.
When he ascended the throne, she became his empress. He had promised that he would marry no one but her in this life, yet to secure his realm, he had no choice but to break his vow and marry again and again. She understood. For the sake of political advantage, he had her confined, deposed as empress, or sent to the Cold Palace several times. She bore it without complaint and even cooperated with him fully.
For her sake, he vowed that one day he would give up everything and travel the world with her, repaying all she had done for him. He would love her with his life, and love no one but her, all for what she had given him.
