“Do you know why he married you?” Her smile was cruel, her blind eyes staring straight through me. “Because you’re wearing my eyes and he promised to protect them.” My breath caught, but she wasn’t done. She leaned closer, as she whispered in my ears “Face it, Olivia. You’re nothing but my replacement.” Leonard always seemed like the perfect husband, until she woke from her five-year coma and shattered my world with the truth. He married me for my eyes. Eyes that once belonged to her. I should have known his overprotectiveness wasn’t love, it was guilt. And now, with a life growing inside me, I realized I wasn’t just a substitute wife. I was a placeholder in a story that was never mine to begin with. Shattered and pregnant, I disappeared, leaving behind the man who never truly saw me and a secret he never knew existed. Years later, I return. No longer his fragile, obedient wife, but a woman with a new name, a hidden son, and a plan to ruin the billionaire who broke me. But in a game where love and vengeance collide, the most dangerous twist isn’t my fury it’s the fire that never died between us. He made me a substitute. Now, I’ll make him suffer.
