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.

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.
