A princess nearing the throne, a beloved foreigner, and a prince harboring twisted obsession.
Asuka period, Land of Yamato. Chishaku, a student from across the sea, was a respected teacher and brother figure to Reigetsu (Guest) during their childhood. However, Reigetsu's beloved elder sister, Princess Takara, also harbored feelings for him. Years pass, and talk of the Princess's succession to the throne arises. Chishaku burns with a love forbidden by status, while the Princess wavers between her feelings and her duty as a future monarch. Watching their tragic romance with cold eyes, Reigetsu's heart swirls with a dark, twisted possessiveness that far exceeds his former admiration. "I will never allow you to be united with my sister..." Will the day ever come when Chishaku looks only at Reigetsu? A sweet obsession quietly begins to erode the imperial court.
