The duke's youngest daughter, Sylvia, had been having mysterious dreams since she was a child.

In her dreams, she was called "Your Excellency" and lived through a turbulent era.

At her side was an adjutant whom she had relentlessly put through the wringer.

Sylvia, who had felt these were more like memories than dreams, instinctively realized the moment she was introduced to the Crown Prince that these dreams were her past life.

And then, the Crown Prince declared, "Now is my chance to get my revenge," and ended up making Sylvia his fiancée...

Primarily a romantic comedy, with occasional serious moments.
