Hua Luoluo, a modern online writer, accidentally traveled through time and became the unpopular Princess Jing'an because she stayed up late to finish her manuscript. She originally thought she would suffer a lot in the prince's palace, but with her modern novel ideas and cleverness, she not only easily solved all kinds of difficulties, but also made the cold-faced prince look at her differently. By chance, Hua Luoluo got acquainted with the current emperor. Her unique insights and lively personality made the emperor regard her as a good friend, and he often discussed the ways of governing the country with her.
While on a mission to a neighboring country, Hua Luoluo became an irresistible friend with the prince of the territory. The two talked about poetry, songs, anecdotes, and jointly promoted cultural exchanges between the two countries. In this series of experiences, the relationship between Hua Luoluo and the prince also unknowingly heated up. From the initial respect of each other as guests, to later working side by side, they jointly faced various conspiracies inside and outside the court. In the end, Hua Luoluo gained a happy love and carved out her own world in ancient times.
