Misery seems everlasting in Miyo Saimori's life. Born from an arranged marriage, she was quickly discarded after her mother's tragic death. Her father remarried, and her younger half-sister Kaya received all the affection, while Miyo was degraded to a lowly servant. Lacking the strength to fight against her family's abuse, Miyo loses hope that her luck will ever turn. Unexpectedly, Miyo's father summons her to deliver surprising news: she is to marry Kiyoka Kudou, the head of the distinguished Kudou family. Despite his noble background, Kiyoka is known to be a callous man who has thus far dismissed all of his former fiancées. Upon arriving at the Kudou household, Miyo expects coarse treatment and to be tossed aside. However, contrary to her assumptions, Kiyoka shows her the kindness and love that she has desperately needed. Marrying Kiyoka may be Miyo's one chance to break free from her neglectful family and embrace a life of happiness. [Written by MAL Rewrite]
