The protagonist inhabits the body of Ophelia, the villainess from the story "The Crown Prince Returns." Despite believing she could succeed like other reincarnated protagonists, she has repeatedly failed and died in various ways across multiple attempts. Each time, she ends up dying, even when deviating from the original plot. Determined to die on her own terms, she requests a slow-acting poison. However, those around her, including someone who questions if she will leave him after ascending the throne and another who expresses a desire to know her better, are preventing her from doing so easily.
