After her soul awakened, Xingzhou regained the memories of her previous life, only to discover that something about the world she lived in now seemed... a little off?! Before her memories returned, the country enjoyed peace and prosperity, and foreign nations came to pay tribute. Xingzhou was the dynasty's only legitimate princess, adored by all. Above her were the emperor and empress, a young couple deeply in love; beside her was her handsome, dashing crown prince brother; and below her were friends who constantly buttered up the princess. After regaining her memories, however, Xingzhou discovered that a whole host of strange consorts had appeared in the imperial harem, each madly in love with her father. Her father went on a tour and brought back a noble consort, who turned out to be the crown prince's true love. The noble consort and her older brother put on one tragic romance after another. Strange things were happening in several dukes' estates, too. Xingzhou felt certain that something was wrong with this world.
