Rishe Irmgard Weitzner is caught in a recurring predicament: her fiancé breaks off their engagement in public, and her ducal family intends to cast her out. Yet Rishe stays composed, having lived through six cycles of rebirth where she pursued different goals but always ended up embroiled in conflicts that led to her death. For her seventh life, she longs for a peaceful and ordinary existence.
However, Rishe’s plans get complicated by Arnold Hein, the heir to the Galkhein Kingdom, who is fated to take the throne and become a tyrant that launches a massive invasion of neighboring lands. Arnold is also the one who caused Rishe’s death in past loops. So it comes as a shock when he immediately proposes marriage to her. To secure the calm life she desires, Rishe considers accepting Arnold’s offer and looks into the reasons behind his harsh actions—to stop the coming war.
