Kourtney Elijah is the eldest daughter of the Elijah family in New York. Due to her stepmother's scheme, she was sent to the countryside by her despicable father at a young age. When the patriarch of the Elijah family celebrated his 60th birthday, they brought her back. She returned quietly, only to be mocked as a rural underachiever and poor girl, which angered the influential figures. A professor from a prestigious university said, "Underachiever? That's a joke! Let me introduce you to the genius who top universities worldwide are vying for!" A billionaire exclaimed, "Poor girl? Nonsense! All my wealth is thanks to Kourtney's contributions!" A certain man declared, "This is my wife. Whoever dares to mock her, I will annihilate them!"

"What are you doing? You’re not supposed to remember." My voice trembled as he smirked, fingers sliding into my hair, tugging just enough to make me gasp. "You’re my wife, Eve." His lips brushed my ear, his breath hot, teasing. "It doesn’t matter how long it’s been. You’re still mine." His grip tightened as he pressed closer, his body flush against mine.

After I transmigrate into a Gary Stu novel as the evil male supporting lead, a system appears in my mind. It tells me that as long as I can conquer one of the female leads, I will be able to return to my original world with a healthy body. But I've failed in my conquest. There are a few female leads in this novel. There's the fake heiress, Leslie Jackman, who I have grown up with and have viewed as my older sister. The true heiress, Miranda Suller, is a boxer who happens to be seatmates with me during our high school times. My childhood sweetheart, Catherine Langdon, who's also a genius surgeon, happens to be one of the female leads too. Heck, even my own daughter, Natalie Jackman… my own flesh and blood… All of them are quick to fall for Gabriel Linner, the poor yet strong-willed young man who's also known as the Gary Stu of this novel. Because of that, they hate me deeply. The system sighs before telling me that as long as I can die in the hands of any of the female leads, it will let me return to my original world. Later on, I use all of the tricks up my sleeve and succeed in getting killed by the female leads. But why is it that they've lost their minds after I die?

I was the daughter of a human noble house, and I married the man I'd fallen for at first sight: Adrian, heir to the vampire Prince. Adrian was unfailingly gentle with me. Every wedding anniversary, jewelry arrived at my door. Everyone said I was the luckiest woman alive. What they didn't know was that on our wedding night, Adrian told me not to let myself hope for anything from him. The anniversary gifts were chosen by his assistant. He never once celebrated with me. In ten years of marriage, Adrian went through more lovers than I could count. Every time, I was the one who wrote the check and dismissed the women he'd grown tired of. This time, I cleaned up after him as usual. That night, he wrapped his arms around me from behind, buried his face in my shoulder, and murmured his praise. “Elena, I always knew you were the sensible one.” I gave a faint smile and slipped out of his arms. “I can do you one last favor.” “Let's get a divorce.” The gentle smile stayed on his lips. Only his eyes went cold for the space of a breath. “Don't be like this. I'll spend more time with you these next few days.” When I turned my face away, Adrian assumed I was slipping back into my old self. I would weep, demanding to know why he couldn't even try to love me. But he didn't know. This time was different. I was dying, and soon I'd be leaving him for good.

My sister-in-law is eight months pregnant. One day, she gets pushed to the ground and starts bleeding heavily. She's then taken to the hospital right away. As I drive by, I quickly roll up the window and pretend not to notice. I step on the accelerator and speed away. In my past life, though, things were different. The moment I saw her collapse, I sprang into action and took her to the hospital without delay. She was in critical condition. After the heavy bleeding, she developed amniotic fluid embolism. My husband was the city's top obstetrician. Thus, I called him urgently, pleading for him to come straight to the hospital. However, he accused me of jealousy. He was having dinner with his first love's family, after all. He claimed that I was exploiting my sister-in-law's accident to force him to come back. By the time my in-laws arrived, my sister-in-law had already succumbed to the amniotic fluid embolism. Her family blamed me for her death, convinced I had stirred trouble with my husband and brought about her demise. Having just returned from out of town, my brother-in-law believed their accusations without question. Overcome with grief, he stabbed me to death at the funeral. Opening my eyes again, I realize I've been transported back to the very day my sister-in-law is knocked down.
