One day, the elder sister was chosen as an imperial consort and enjoyed a life of luxury. By chance, the younger sister met the emperor, her brother-in-law, whom she had never seen before, and they fell in love. When she saw that her beloved still had feelings for her sister, the younger sister killed her for the sake of her own love. Though she endured many hardships beyond what ordinary people could bear, she succeeded, and from then on the emperor devoted himself exclusively to her.
