In the kingdom of K?zui, Crown Prince Ji Senken is exiled and nearly dies, saved only by the sacrifice of Setsurin. Having narrowly escaped death herself, Setsurin conceals her identity and starts living in the royal palace as a humble servant. Six years later, Ji Senken makes his return to K?zui. For some unexplained reason, he feels an unusual attraction to a specific palace slave. Mistaking this servant for a man, he becomes increasingly obsessed—and eventually falls in love. Amid the power struggles and revenge that disrupt the imperial court, the illicit romance between a prince and a "palace slave" heads toward an uncertain destiny.
