However, Moyena only has eyes for two handsome young men: her cousin, Moluoni, and his best friend, Chen Yuxiu. Despite Moyena's alluring beauty and vivid personality, both she and Moluoni are royal hostages from the Loulan Kingdom for the Han Empire. When war threatens to break out between Han and Loulan, the Emperor devises a scheme to ultimately obtain Moyena while exiling Moluoni and Chen Yuxiu to Loulan as peacemakers. But politics is never so transparent and clear, because the Emperor wasn't able to capture Moyena, so he decided to send a "little punishment" for the Loulan Kingdom...
