One day, Cattleya, the eldest daughter and youngest child of a backwater noble family, receives a suspicious marriage proposal from the Vraage family, one of the most prominent noble families in the country.

Blinded by the favorable conditions—handsome, wealthy, and close in age—Cattleya readily accepts the marriage, but the Duke, whom she meets for the first time, is strangely cold and seems to have no interest in his bride. To make matters worse, during the ceremony, Cattleya overhears the Duke and his companions laughing at and ridiculing her family home.

Enraged and fuming, Cattleya refuses the wedding night, but is practically thrown into the Duke's bedchamber. But there, without understanding what was happening, she is brutally murdered by someone—

"Huh? I came back to life?"

Despite having died, when she opens her eyes, the scene is, for some reason, just before she heads to the Duke's bedchamber. Incredibly, Cattleya has looped back to the worst wedding night!

Killed countless times, each time the worst night begins anew.

Can this slightly dim-witted young lady overcome the death loop?
