Billionaire’s Substitute Mistress

Mia's life turns around when she eavesdrops on a billionaire conversation and dents his expensive car. Allen makes Mia his substitute bride when he finds out his fiance has been cheating on him as a payment for denting his car.  Mia turns from a girl with debts to a billionaire's wife in just a day. After she signs a contract to be the billionaire's wife for a year,  she is determined to stay until the end just because of the payment she will receive. Will she be able to abide by the rules of the contract? Will she be able to stay with him for a year even though his ex keeps trying to break them apart? 

"Zeke, was I just a substitute?" I asked, my voice trembling. "All these years, was I nothing but a replacement?" But then again, he remained silent. And I took that as a 'yes' to my questions. "It's over. The sooner you accept that, the better." Zeke's cold expression remained unchanged. - Discovering she was just a stand-in for her husband's ex, Vivienne Lancaster divorced billionaire Ezekiel Harrington. She signed the papers and walked out of his life, secretly pregnant with twins. Years later, when Ezekiel's company was on the brink of collapse, he needed the help of the elusive and influential mystery designer Viatrix. Little did he know, the designer he had been chasing was none other than Vivienne—his ex-wife. Vivienne had returned and she was ready to get revenge and reclaim her life, while Ezekiel had to face his past mistakes. Could he win back the woman he had taken for granted, or would he fail chasing the billionaire's substitute ex-wife?

"… Are you planning on making me someone else?" I asked, my bottom lip trembling slightly as I began to realize what I had gotten myself into. "Too many questions." He stared straight at me, and then his lips spread in a sly smirk, "You are right, anyways. You are no longer who you used to be. What is your name?" "Persephone Walters." I told him with a hidden plea in my voice. Please don't make me disappear… "From now on, that person is dead. You will now be my girlfriend, and wife-to-be, the elegant Kassandra Aaron." ______________________ She’s a mechanic. He’s one of the richest CEOs in the state. She is also his girlfriend's doppelgänger, and he only needs her as his substitute mistress until his real girlfriend returns, to save his father's business. Falling for each other seems impossible, mostly because Aiden sees another woman through her. However, when his real girlfriend returns, the contract meets its end and they find out that things are not on the original track. How does CEO—Isaac Bates remind himself that the mechanic—Persephone Walters is way out of his league? How do they defeat the numerous obstacles that stand against their love?

“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.

Mia Scott had one rule: never let anyone know who she really was. For years she lived without the Scott name, the mansion, or the empire, just a quiet apartment and a man she believed loved her for exactly what she showed him. She was wrong about the man. Wrong about her best friend. Wrong about everything she thought she had built. One humiliating night at a bar. One ruined suit. One cold marriage alliance with Ethan Brook, the most powerful CEO in the country and the most emotionally unavailable man she has ever met. She didn’t want him. He didn’t want her. They both had rules. Then she walked into her father’s company as the hidden daughter nobody expected, rebuilt herself from the inside out, and started winning battles everyone assumed she would lose. And somewhere between the boardroom rivalries, the betrayals, the connections neither of them planned, the rules stopped working. Ethan Brooks doesn’t do love anymore. His wife is dead and the guilt lives in his chest like something permanent. He never expected Mia will be the one person who could reach it. From being betrayed to boardrooms. From hidden identity to undeniable power. From a cold wedding to something neither of them saw coming. Replacing the Billionaire’s Wife is a slow burn billionaire romance following a strong willed lady who goes from heartbreak to empire and finds love after marriage with the one man who never planned to give it. Girl power. Hidden identity. CEO romance. Weak to strong. Betrayal. Love after marriage. Some women are underestimated once. Mia Scott made sure it never happened twice.

When billionaire CEO Ethan Kingsley is left at the altar by his fiancée, the last person he expects to face is her younger sister. Emma Bennett has no intention of becoming anyone's substitute. But with her family's future hanging by a thread and a devastating truth threatening to destroy everything they have, she agrees to a contract marriage on one condition: this will be a marriage in name only. Ethan accepts without hesitation. What begins as a desperate deal soon becomes a dangerous game of secrets, betrayal, and undeniable attraction. As Emma uncovers the real reason Ethan spent years searching for her, she realizes their marriage was never as accidental as it seemed. But when the runaway bride returns, demanding the life she abandoned, old wounds reopen and impossible choices must be made. Can a substitute bride become the only woman in a billionaire's heart, or will the wrong vow cost them the love they never saw coming?
