In this scenario, Rishe Irmgard Weitzner is faced with a difficult decision. Her fiancé has publicly ended their engagement, and her ducal family is disowning her due to shame.

However, she hopes for her seventh reincarnation to be peaceful and uneventful. Little does she know that Arnold Hein, the crown prince of Galkhein Kingdom, will be present. He is destined to take over the throne and become a tyrant who starts a war with neighboring countries. To make matters worse, Arnold is the one who killed Rishe in her previous life. Despite this, Arnold proposes to Rishe on the spot. In order to achieve her desired life, Rishe must now consider accepting his proposal and uncovering the reasons behind his violent actions to prevent the war from ever happening.
