My best friend, Clara Wilder, has baked an apple pie for me. But I don't hesitate to give it to my pregnant dog. That's because I've gotten reborn. In my previous lifetime, Clara had bound the Fertility Transfer System to me. If I were to eat the food she made, the baby I was pregnant with would be transferred into her womb, and she would be the one giving birth to them. Clara had married into the wealthy Gray family. For three generations, the Grays were only able to produce one heir each. That was why her in-laws desperately needed her to bear them grandchildren. Since Clara couldn't get pregnant at all, she decided to target me, her newly-wedded best friend. I went to great lengths just to get pregnant every time, but right after I ate the food Clara made, I'd go through a miscarriage by accident. Just like that, Clara was able to give birth to four sons in a row. She became the apple of her in-laws and her husband, Colton Gray's eye, which made her ego swell like mad. In the end, Clara and Colton hatched a plot where they accused me of cheating on my own husband. With my reputation flushed down the drain, I got kicked out by my in-laws. In the end, I starved to death on the streets without a penny under my name. At the end of the day, Clara wants children very badly, doesn't she? After I get reborn, I decide to give her some special "babies".

Al, was thrown into another world for no apparent reason. A new world filled with magical things. However, this wasn't the first time he had been reincarnated. He thought he was just an ordinary youth, but it turned out that his identity was so extraordinary in his first reincarnation. There were his harems still waiting for his arrival. Will he meet them soon and what will happen?

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!

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline. On the day of her birthday, her body gave up and she died alone from exhaustion. Upon receiving the chance of a new life, she was reincarnated as the daughter of the Duke of Polvaros and acquired the prose of living a comfortable life ahead of her. Only she doesn't want that. She wants to work. Even if it's being a maid, a hired killer, or an adventurer. She will do it. The only thing wrong with Evy is that she has no concept of reincarnation or being isekaid. In her head, she was kidnapped to a faraway land… stranded in a place far away from Japan. So she has to learn things as she goes with as little knowledge as anyone else. Having no sense of ever knowing that she was living in fantasy nor knowing the destruction that lies ahead in the future. Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.
