Embodying the culture that she experienced in her previous life, she was a reincarnator with the ability to make the empire flourish. In the first timeline, Rossite is able to use her unique ability, the power of implementation. Being bullied by the reincarnator Karina, she is even accused of attempting to murder the Duke of Identino, which leads to her execution. At that moment, she recalls the memories of her past life as a paramedic. Rossite realizes that she is the real reincarnator and regresses on the brink of death. The first thing Rossite sees after her regression is Duke Identino, saying he has come to find the "emperor's lost daughter." Rossite goes to the imperial capital with him, but even there, Karina slanders Rossite by spreading rumors that she is a fake princess... The emperor, paying no mind to her words, calls her the real daughter. He feels even more drawn to Rossite, who is called the fake princess. 'Why is it that being with this child is as comfortable and enjoyable as being with the empress?' Could she really be the emperor's lost daughter? (Source: Kakao Entertainment Corp., translated)
