A witch who has lived for thousands of years has grown bored with her own life and decided to leave it. Since she is an immortal, her soul cannot leave the world. However, what she can do is transfer her soul to another body. By a stroke of luck, she happens to enter the body of a princess. She was considered a miracle because when the Empress gave birth to her, the princess instantly died, along with the Empress. What the witch didn't know was that she has entered such a predicament. She has to endure the love of the cruel Emperor and possessiveness of the crazy twin princes! What will her life be at the hands of such a loving family? In addition, it seems that this body contains mana that was lost in the royal family centuries ago!

On the day I return to my home to reunite with my actual family, Melanie Stewart, the fake heiress, shows up in front of me. Her neck is completely riddled with hickeys. Instantly, countless live comments appear in the air around me. "Poor Yvonne! She thought she could start living a comfortable and lavish life now that she had been accepted by her actual family. Little does she know that Melanie has already formed a pact with the transfer system!" "Melanie is a loose woman by nature, and she loves sleeping with countless men. After getting bound to the system, the children she gets pregnant with will be transferred into Yvonne's womb instead." "Yvonne will proceed to give birth to dozens of bastard children, thus humiliating her family to no end. She ends up getting cast out of her family by her own parents!" "The truth is, there's a solution to this situation. Yvonne can just remove her uterus so that the system won't work at all. Alas, she doesn't know about that." I stop in my tracks at that moment. In my previous life, I had believed the live comments. As such, I traveled to a hospital to get my uterus removed overnight. But the next day, Melanie blew the whistle on me to my parents. She claimed that I wanted to get rid of my uterus in order to cut down the risks completely for the sake of having as much fun as I wanted with other men. My parents were completely disappointed in me. My fiance refused to enter a marriage alliance with me, a woman who could no longer give birth, as well. In the end, I died from a post-surgical infection. However, Melanie obtained everything that was supposed to be mine, to begin with. That was how she became successful in life. When I open my eyes again, I realize I've returned to the day I'm bound to reunite with my family.
