I forced Maddox, Mr. Tough Guy, into putting on a sexy dress, essentially killing his chances of a social life. I grabbed the bottom of the ever-aloof Zane and made him red in the face. I kicked Damian, the crybaby, into the ground, and all he could do was glare at me through his tearful eyes. My aggressive antics only fueled their resentment. “One of these days, I’ll get you.” I winked at them without a care. “I’ll be waiting.” The day they crossed paths with the female lead would be the day I left this world. Their revenge didn’t scare me one bit. Little did I know, the time would come when I would be proven wrong. While I scrambled to get away in tears, he said softly, “Save your strength. The night is still young.”

After discovering I was pregnant at the military family hospital, I began hearing the voice of my unborn child. When my brother came to visit, I was just about to share the good news with him when my baby sobbed, stopping me in my tracks. "Don't do it! Aunt May's pregnant too, and Uncle Jerry is worried that you'd stop helping them once I'm born. He'll force you to abort me!" And so, I contacted the security department to stop my brother from entering. The very next day, news came that he had been brutally murdered by his enemies, and that his body had been thrown into the river. That's when I knew that he hadn't come to visit family, he had come seeking refuge after provoking some people he shouldn't have. May, my sister-in-law, was devastated and blamed me for his death. At the lowest point of my life, my husband, Ben, stayed by my side, encouraging me to get my act back together, but the baby in my womb continued speaking: "Dad's kissing Aunt May right now! He's so good to you because he feels guilty for cheating on you!" When I came to my senses, I had already stormed into the military compound to catch them in the act. But inside was an important military strategy meeting, and Ben was both punished and demoted for what I did. Disappointed, he asked me for a divorce, yet the baby laughed and said, "Dad's just playing chicken! I guarantee that if you agree to the divorce, he'll be begging for you to come back to him within three days. He loves you too much to let you go!" I signed the divorce letter and waited for a whole three months, only for him to get married to another woman. I rushed to the wedding in desperation, only to be dragged into an alleyway by drunk thugs. Yet, the entire time, my child was cheering happily! Even until my dying breath, I couldn't understand why my child wanted me to be destroyed! When I opened my eyes again, I returned to the day I found out I was pregnant…

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".

My new next-door neighbour was a total hottie. He fixed my plumbing and brought over baked goods, basically the perfect gentleman. However, I could see a bright red stat hanging over his head. Malice Level: 1,111 It could only mean he was out to get me. One night, he snapped my stalker’s wrist, and red digits reset to zero. Somehow, his murder meter turned into a pink possessiveness score of 9,999+. He wiped the blood off his hand, his tone eerily gentle. “Who gave you the right to touch my prey?”

I had agreed to pay 10,000 at the wedding. At the very last minute, my mother-in-law, Alice Thompson, suddenly raised it to 500,000. I went to confront them. My husband, Dylan Forrest, kept his head down, pretending not to hear a thing as he looked at his phone. Alice rolled her eyes, clearly about to brush me off with some excuse. But instead, the truth spilled out of her mouth against her will. "Of course we have to take advantage of you being pregnant and unable to run to squeeze as much money as we can. It's the perfect timing to use it to buy Gideon a house, paid in full!" The words were like a silent explosion. I was so furious I actually laughed. "So, that's the plan? You're trying to strip me for everything I have? If I don't pay, does that mean there's no wedding?" Alice clamped a hand over her mouth, panic flashing across her face. But her voice came out louder than ever, like it was blasting through a speaker. "If you don't pay, then get lost! You're just a pregnant, used woman. Who else would want you besides Dylan?" The guests erupted instantly. Dylan's face went pale as paper. I smiled. Then a mechanical voice rang in my head. "Honest Lies System activated. Malicious fraud detected. Reward granted: 100 billion. Match assigned: the richest man in Lumeria at the next table." "Fine," I said softly. "You said it yourself." I wanted to see just how the Forrests planned to show their faces tomorrow after every ugly truth they'd tried to hide was dragged out into the open.
