Duchess Asera, whose prince fiancé since birth was taken by a Saintess from another world, and who had her engagement publicly annulled, was preparing for a journey, recalling a love she had once given up on.

Just then, Duke Rots from a neighboring country – her classmate from the Royal Academy and none other than her first love – rushed to her side with a once-in-a-lifetime proposal.

Asera took Rots's hand and thus became a bride in the neighboring country, but... in truth, she was secretly seething with rage.
