Muji no Koukyuu: Fukushuu no Biki

Suiren is overjoyed when Prince Gongyan, a member of the royal family, proposes marriage to her. However, Gongyan is falsely accused and murdered by his older brother, the Crown Prince Yintan, and Suiren is forcibly taken away by Yintan, who wanted her as a concubine. However, when she catches the eye of the Emperor, the father of both princes, he takes her into the palace harem instead. In despair, Suiren contemplated suicide, but then she meets Xiqing, a military officer who served as Gongyan's bodyguard, now condemned to become a eunuch in the harem for his role in Gongyan's death. In the treacherous halls of the harem, the two plan to take revenge using Xiqing's knowledge of the palace and Suiren's beauty as their weapons. A shocking Chinese-style dark-fantasy!
