Zhenya and Taekjoo ruled the underworld like twin gods of sin. Both were feared mafia bosses, untouchable in their own right—but bound together by a dangerous, irresistible tension. Zhenya was a vampire, ancient and elegant, his presence cold and intoxicating. Taekjoo, an angel who had fallen from heaven, wore his beauty like a weapon—sharp, blinding, and lethal.

They hated each other. They wanted each other.

Taekjoo was younger, devastatingly handsome, and impossibly strong. His calm gaze hid cruelty, his angelic face disguising the most ruthless mind in the criminal world. Wealth clung to him like a second skin, and danger followed wherever he went. Zhenya found himself watching him more than he should—memorizing the curve of his smile, the confidence in his movements, the way power radiated off him without effort.

One night, Zhenya summoned him.

Taekjoo stepped inside, wings hidden, eyes sharp. “What do you want, Zhenya?” he asked, voice smooth but edged with threat. “Why did you call me here this time?”

Zhenya leaned back, lips curling into a slow, knowing smile. He hadn’t called him just for business—but business was the excuse.

Finally, he spoke. “I want an alliance.”

Taekjoo’s gaze darkened.

Zhenya continued, his voice low and deliberate. He wanted Taekjoo by his side—to form a deadly partnership and wipe out the werewolf clans rising against them. A war was coming, and together, they would be unstoppable.

What neither of them said aloud was far more dangerous than the deal itself: this alliance could either rule the world… or destroy them both.
