Zhu Chang'an, a princess who transmigrates into a book × Pei Jue, a sickly, obsessive young general
Zhu Chang'an accidentally transmigrated into a novel as a princess who appeared for only one episode before dying, and whose kingdom would later be overthrown by the male lead. She planned to kill him and bring the story to an early end, then find a way back home. But she couldn’t kill him, so she had no choice but to cling to the female lead and help the male lead get his revenge. That way, she could still survive until the ending. But when she faced Pei Jue, who in the original story had eyes only for his elder sister, she couldn’t control her feelings.
The male lead was the second male lead in the original story. At first, he had eyes only for the original female lead. Later, he was drawn to Zhu Chang'an without realizing it, and only then understood that his concern for his elder sister had been nothing more than familial affection.
