One day later, Xander’s empire begins to crumble. The only person who can save him is the newly revealed CEO of the Vance Global Empire—the woman he just threw away. Xander thought he was the King of Aurelia City, but he’s about to find out he was only reigning because his wife allowed it. Now, he’s on his knees, but Seraphina is no longer listening.

Luca Graven, an orphan cursed by poverty, worked under the man loathed the most— Dante Solis. He was a wealthy, powerful mafia leader who had the strongest men, including Luca himself cowering in fear. Unfortunately, Dante took a liking to him. He brought him into his home, enslaved him, treated him like rubbish….but, he never hurt him beyond his limits. Maybe that was why Luca never fully hated him, and maybe, just maybe, that was why he wanted him. Until, a new version of him shows up. He looked exactly like Dante, same voice even, but completely different personalities. This version listened, cared for him, no longer saw him as a mere slave, he nurtured him and treated him like he meant something for once. Of course to Luca, Dante had miraculously grown a heart but that person that showed him kindness and mercy wasn’t Dante. It was Allen Pierce—his doppelganger. Now torn between two different people, yet drawn to each of them and their different souls, he has to make a decision. But they don’t make it easy. Luca wasn’t the only one fighting to choose, they were both fighting to be chosen.

"Bitch! Still trying to play innocent?" Jasper said as he tightened his grip on Renea's throat and squeezed harder. Then he used his other hand and took out the phone from his suit pocket and played the video of two people having sex in front of Renea... What was even more shocking was that the woman in the video was Renea Morris, but the man in the video was not Jasper. Renea struggled to get the phone out of Jasper's hand and tried to explain, "Jasper, it was not what you think... I... I can..." Jasper looked at Renea with disgusted eyes as he said, "Let's call off the wedding. I can't marry a woman like you." After saying that, Jasper walked out of the store. Renea runs after Jasper. But then she sees Jasper passionately kissing her sister Kailey. And she hears everything, that her sleeping with strange men was all a plan of the Vipers for the last two days, and that their goal was to get out of this stupid marriage. Even her adoptive parents were involved in this... They are all doing this to her because of the inheritance left by her grandfather... Renea's heart was filled with anger and she wanted to expose them to the public... But before she could do anything, Kailey had pushed her in front of the car and she was killed... But when Renea opened her eyes, she found herself in the car with Kailey... She realized that she was reborn and went back to the time when it all started... Renea looked at the people who had hurt her in her previous life and her lips curled into a cold smile... She was back... But this time... she was back for revenge...

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

After transmigrating into a novel, I realized the heroine and I had the exact same name. Naturally, I thought I had transmigrated into the female lead. So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me. He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing. Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me. Heartbroken, I packed my bags and got ready to disappear. The next second, he pinned me against the wall. "Where are you going? Already bored of me, sweetheart?"
