Lunatia, the daughter of a viscount, was nothing more than a tool exploited by her family for her "clairvoyance." Used even by her own fiancé, she eventually pays the price for her abilities by losing sight in one eye. The only future she sees awaiting her is one where all five senses are lost… Determined to live on her own terms and die an honorable death, Lunatia escapes from home. She finds refuge in the manor of the “Marquess of the Lunar Eclipse,” who is rumored to be seeking a new bride. With daring resolve, she proposes to this fearsome, seemingly inhumane man: “If you make me your bride, I will read your future once a day. You don’t have to love me.

Though Lunatia tries to keep her dying senses a secret, the truth starts to come apart at the seams. But why is her supposedly cold-hearted husband suddenly revealing unexpected depths of devotion...?
