The Devil's Favorite Sin

He wasn't meant to feel. She wasn't meant to stay. But sin was never meant to be resisted.

In the shadows of a city ruled by blood and secrets, Seungcheol-a ruthless mafia king known as "The Devil"-moves with cold precision. He doesn't love. He doesn't break. Until he sees her.

Y/N is everything he's not: soft where he's sharp, kind where he's cruel, light in his eternal darkness. She's a commoner, untouched by the underworld-until one night in his exclusive club shatters the divide. One look, and he decides: she's his.

But Y/N doesn't bow easily. She's not a woman who obeys threats or wilts under control. As she's dragged deeper into Seungcheol's world, rebellion burns brighter in her eyes-and so does the pull between them.

Now, it's a war of dominance and desire, of stolen touches and unspoken truths. In a world where love is weakness and loyalty is bought in blood, she might be his favorite sin... or his ultimate ruin.

Obsession cuts deeper than bullets. And some devils don't burn alone.
