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.

A thirty-year-old office lady, who got into an accident and is now trapped inside a novel series she loves. She was reincarnated into one of the side character extras of the story and meets in person the tyrant magician, the playboy prince, and the clueless female lead of the story.

The first thing I do after being reborn is secretly keeping six stunning male models behind my wealthy husband’s back. I seduce them and sleep with them for 999 days to get myself pregnant. I do all this because in my past life, my husband found out that he had asthenozoospermia and married me because I am known for being fertile. He wants to carry on the family line so that he will have a successor to inherit the family fortune. I try everything I can to get pregnant, but nothing works. Conversely, my infertile best friend gives birth to twins and triplets within two years after marrying a 70-year-old man. When my wealthy husband hears that my best friend is blessed with children, he is immediately captivated. They get together behind my back and even arrange for someone to run me over with a car when I find out the truth. After my death, I discover that my best friend has bound herself to the child switch system. Any child I am impregnated with is transferred into her womb. My best friend's infertility is transferred to me in return. When I open my eyes again, I find myself back on the day when my husband married me and brought me home. I smile happily when I think about all the things that took place in my past life. My best friend wants lots of children, doesn't she? If so, I will make her experience the joy of having 18 babies in one pregnancy!
