Alluring Ugly Princess

She was originally the daughter of a wealthy family, but she inexplicably traveled through time and space to a little princess from the Eastern Dynasty because of a glass of cocktail. Unfortunately, the little princess just came back from the fire, her appearance was ruined, and she changed from the most beautiful girl to the most ugly girl. An ugly girl should be an ugly girl. She thought that as long as she was Si Jiayan, she would be fine, as long as she left the court, and as long as she didn't become a pawn of politics. It's just that the wheel of fate never changes based on one person's wishes. She met him - Tuoba Yi, and from then on, her destiny really began. He thought that she would become the person in his heart amidst repeated crises and misunderstandings, but the "difference" in her appearance made it impossible for him to recognize her. In the end, he sent her to the battlefield and made her a pawn. After knowing the truth, will they finally get married or part ways.
