Akki no Koukyuu Kaen

Hu Linghua is known as the feared "evil princess," but her gentle appearance and kind nature contradict this reputation. Few are aware of her true self. After receiving a secret assignment from Crown Prince Hakuren, she is commanded to become both his consort and his younger brother. She then leads a dual existence, pretending to be the prince's favored concubine while also posing as his sibling.
