The rain fell hard over Seoul that night, neon lights glinting against the slick pavement. You—barely fifteen, a prodigy the world didn’t know existed—stood at the head of the city’s police strike force. The youngest general in history. To most, you were a ghost in uniform: a brilliant tactician who dismantled cartels before they even knew they were being watched.

And across the city stood your nemesis: Jonah Kim, heir to the Kim syndicate. Ruthless. Calculated. A man who wielded his name like a blade, ruling the underground with charisma and cruelty.

Jonah didn’t know. Didn’t know the police general he cursed in the shadows was just a child. Didn’t know you had already slipped past his defenses and into his family itself.

Because when you removed your badge and polished shoes, you became his brother.

Or so they thought.

Years ago, during a bloody police raid on the Kim mansion, a baby vanished. The Kims believed their infant son was killed that night. In truth, you were taken—not by chance, but by design. The police, desperate for an advantage against crime syndicates, handed you over to a secret lab. There, they tore away your humanity and rebuilt you into something else. Enhanced reflexes. An intellect beyond the charts. Cold, flawless logic sharpened by endless drills. You were no longer just human—you were their weapon.

And now, the experiment had come full circle. The prodigy general who orchestrated raids and ran operations against mafias had infiltrated the very bloodline he was stolen from.

Jonah accepted you, skeptical at first, but your resemblance to old family portraits was uncanny. The Kims welcomed their “lost brother” home, blind to the truth that you already wore the badge of their greatest enemy.

But the cruelest twist?

You weren’t pretending. You really were Jonah’s brother. The lost Kim heir. The mafia prince turned weapon of the law.

Every time Jonah looked into your eyes, he saw the past he thought had been stolen. And every time you looked back, you saw a brother you were raised to destroy.

The city became your battlefield.

At night, Jonah schemed to crush the mysterious “child general” who hunted his empire. By day, he confided in you, trusting you as his blood, his confidant. Neither of you realizing the threads of fate had tied you both into the cruelest of knots.
