Han Jisung is a genius-brilliant, eccentric, and dangerously underestimated. As the reclusive tech mastermind behind the elite crime-fighting agency known as the Phantoms, he crafts the weapons and gadgets that bring empires to their knees. They call him the Phantoms' Jewel-rare, fragile, invaluable.

But Jisung's quiet world shatters when he's abducted by Lee Minho, the cold-blooded leader of the infamous mafia syndicate, the Ring of Fire. Known only as Lucifer, Minho believes Jisung is the key to obliterating his rivals, the Lamia. At first, Jisung is nothing more than a tool, a pawn in a bloody war. Until he becomes something more-dangerously more.

As sparks fly and loyalties blur, Jisung finds himself drawn to the very man who tore him from everything he knew. But love in the underworld comes at a price, especially when it's forbidden.

Bang Chan-codename Terror, leader of the Phantoms and once Jisung's lover-won't let his jewel go without a fight. Vengeful and unrelenting, he will burn the world down to bring Jisung home... or watch it all turn to ash trying.

Love. Betrayal. Obsession.
In a world where alliances shift like smoke and love is the greatest sin of all, The Sin of Love dares to ask:
How do you choose between the devil who stole you... and the angel who let you go?
