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.

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!
