I was accused of attempting to kill my younger sister. No one believed in me, no one to wrap me up. Even my own family. 14-year-old Alisa. I was a 4th princess of Edenberg, and I was miserably thirsty in front of people. I looked at my younger sister, hoping she would stop them from killing me. But what I saw was a devil laughing happily at the sight of me dying. After being executed I opened my new eyes. I was in someone's womb and I could hear voices. Before falling unconscious again I heard a boy's voice saying "Welcome, my precious little sister" He laughed warmly "The whole world loves you." She was reborn as the first princess of the Elmir empire, who was a rival of the Edenburg empire.
