My older sister was always kind-hearted, while I was born a natural troublemaker. When the intense heatwave struck, our family stocked up on supplies and stayed indoors. My sister saw a little boy, who seemed about seven or eight years old, crying and asking for help. She decided to take him in. “We’ve plenty of supplies anyway. One more person won’t make much difference. Besides, he’s just a child.” I warned her that the boy looked oddly mature and might not be as innocent as he seemed. I suggested we observe him a bit longer. She said I was a cold-hearted troublemaker by nature. Then, she went and let him in anyway. Not just that, but she also convinced our mother to force me to share a room with the boy. That night, the scheming “little boy” secretly climbed into my bed. I was brutally assaulted. Yet my sister told me to let bygones be bygones and marry him. To force me to obey, she locked me out on the balcony at over 140 °F. Enraged, I set a fire and killed everyone. When I opened my eyes again and saw my sister safe and unharmed, I smiled. This time, I would show them what a troublemaker really was.

I had stopped pretending the night Sebastian sailed past our bedroom door for the third time and didn’t look back. I had married him to keep my father’s company intact. Out of my father's desperation. The vows were for the cameras and the board, everything else was ledger entries and quiet compromises. He chased his affairs in public while I held the facade. He saw my composure and called it martyrdom. He never figured out that my calm was armor, not devotion. Then Samantha came home, twenty-three, luminous, curious, the kind of warmth that made places in me I’d kept cordoned off ache. She drifted into my life with easy laughter and careless questions. A sister-in-law, that became my obsession. We started with late-night talks, her voice soft in an empty house, her hand brushing mine while we pretended we were discussing nothing at all. Those small touches stopped being accidental, but deliberate. While Sebastian was busy elsewhere, I took his sister. Not to win anything on a balance sheet, not to score a victory, but to finally have the means to protect who I am, and who I love. Samantha was bewildered at first, shame and curiosity tangling on her face, but the way she leaned into the moments we stole told me more than words ever could. It was messy and urgent and selfish. She became my refuge and my ruin. The tenderness I had once sold to survive became a liability I was suddenly proud to bear. When the scandal around Sebastian crescendoed, I didn’t hide behind the marriage or the name. I stepped into the light, shoulder to shoulder with her, exposed and fierce. I traded anonymity for that, truth wrapped in possession, and I, Mikayla Stonefield, would have done it again.

I return to the country after attending an international anesthesia academic conference. That's when I see the news of my boyfriend and twin sister getting married. I'm anxious to verify its authenticity, but my sister drugs me and induces me. "A substitute's child will only be an unwelcome bastard even if it's born. I'm just helping it move on to a better life." Then, she slices me open with a scalpel. She gouges my womb out, causing me to die from significant blood loss. Meanwhile, my boyfriend believes her lies. He's sure he's not the father of my child. He ignores my messages begging him to save me. Instead, he spreads the word about me eloping with someone else. He even wipes all traces of me from his life. "I will never see her again, forever and ever." Five years later, surveillance footage of my sister cruelly murdering me surfaces.
