My mother-in-law was somehow allergic to me. As long as I was in the house, her skin would break out in rashes, and she would struggle to breathe. The hospital could not find any specific allergen. They said it might be something to do with my scent. To give his mother some relief, my husband Keith asked me to stay in a hotel every weekend. I quietly packed away everything that was mine. I even stopped wearing my favorite perfume just so I could stay home for one extra day. However, her condition only grew worse. The days I was allowed to be home dropped from five days a week to three, and eventually to just one. I never complained. I only hoped she would get better soon. One day, I left work early to pick up a document from home. I heard laughter from inside the house. "Mom, your trick really works! Every time you cough, my brother kicks that woman out." It was Keith's god-sister Caroline, who had studied abroad. My mother-in-law laughed smugly. "Caroline, you're the best. You can cook, and you give great massages. You're nothing like that useless block of wood who's always in the way. "Keith, hurry up and marry Caroline already. Get rid of that woman!" Keith's voice was full of indulgence. "Mom, don't say things like that. Caroline, look at the perfume I bought you. You've worked hard lately." All strength left my body as I stood frozen at the door.

Because of what I witnessed the night before my wedding that really broke my heart. I decided to push my plan of seducing Frederik Wilford for my sister to taste my sweetest revenge for making me feel worthless and unwanted.

The day I died was the same day as my twin sister’s birthday party. She was in tears and was wrapped up in my boyfriend’s arms. My mom was seething with anger and kept calling me over and over again. My brother was clearly upset and sent me a text saying, "You’re so selfish. You just can’t stand to see anyone else happy." Even my usually quiet dad was furious and said, "She’s nothing but an ungrateful brat." I touched my chest. Thankfully, it did not hurt anymore.

Bria Barbara was arranged for a marriage to a Mafia Boss named Theodore Williams. Bria visited her hidden twin sister, Briana Barbara,  who chose to live a normal life instead of being part of the chaotic Mafia world.  In a blink of an eye, Bria Barbara was killed.

As Briana marries Theodore, her hunts begin to catch the one who killed her sister.  But then, what would happen if an unplanned thing became a barrier to her revenge? What would Briana do if she ended up falling for Theodore Williams?  “Watch me avenge her death,” Briana Barbara, her twin sister. 

Arwen was never supposed to be here. Her sister was the beautiful and confident one.
The one promised to billionaire tycoon Caelum Ravencroft. But days before her wedding to billionaire CEO Caelum Ravencroft, the perfect Isolde disappears. To save their family from ruin, her quiet, overlooked sister Arwen is pushed into her place. Caelum is powerful, distant, and used to getting exactly what he wants. He expects a polished bride who fits his world. What he gets instead is Arwen-quiet, thoughtful, an artist who hides her dreams and her pain behind polite smiles. He doesn’t trust her. She doesn’t trust him. But living under the same roof, pretending to be husband and wife, cracks something open neither of them planned. Then a message shatters everything: Don’t trust her. When Arwen’s secret is exposed, she’s thrown out with nothing but heartbreak — and a truth that could change everything. Because while Caelum believed she was lying to him, he never saw the real danger closing in. Now his enemies are circling and his empire is burning. The only woman who can save him is the one he lost. But… She’s already gone. And she’s carrying his heir.

As the youngest daughter of the Costellos, I had always lived in my sister’s shadow. That was until five years ago, when she betrayed the family and ran off with a street thug. I took her place and completed the wedding with Elio Ross. Over the years, he loved and indulged me, but we never got a marriage license. He always said family matters kept him busy, and that, with or without it, I was his wife in his and the family’s eyes. I believed him. Until today… I watched as Elio walked out of the church with my sister Alyssa, who had been missing for five years, both of them wearing the family rings that symbolized their union. At the church entrance, three black SUVs opened their doors simultaneously, and my three brothers stepped out in tailored suits. “The ceremony’s done? We’ve already booked Antonio’s to celebrate Alyssa’s return.” They climbed into the cars, expressing their joy, while no one noticed my pale, shattered face across the street. Later that night, under the guise of apology, my sister let a venomous spider bite me. “A substitute is always a substitute. Now that I’m back, it’s time for you to die.” I screamed for help. However, my husband and my three brothers only rushed to hold my sister, who had pretended she had fallen, without a glance at me, writhing from the poison. They called in every specialist from the hospital, only to tend to my sister’s scraped knee. That was the moment my heart truly broke. After being dragged back from death’s door by the doctors, I made my decision. I picked up the phone and called the International Private Island Exchange. “That isolated, uninhabited island… I’ll take it.”
