“You and I are not well matched. I hereby break off our engagement.”

Cornelia, the daughter of a duke, is informed by Crown Prince Leonhardt during a ball that their engagement is over.

Or so it should have been.

But when she wakes up the next morning, she somehow finds herself back on the morning of the previous day.

Certain that she will once again be told their engagement is canceled at the ball that already ended once before, Cornelia prepares herself—

Yet Leonhardt is acting differently from how he did yesterday…!?

Though their relationship remains awkward, the two decide to work together in order to escape the endlessly repeating “today”…!?
