Rishe Irmgard Weitzner finds herself in a familiar situation: her fiancé is publicly breaking off their engagement, and her ducal family is about to disown her in shame. However, Rishe is not distraught; she has already had six chances to rebuild her life and chase a different passion each time. But she would always get swept up in a war and die, so now she wishes for her seventh reincarnation to be easygoing and uneventful.

In pursuit of her desired life, Rishe must consider accepting Arnold's proposal and discover the reasons behind his brutal actions to stop the war from ever happening.
