You're from a family of contract killers. You and Knox were ordered to go undercover to find and bring home your escaped younger brother. And Knox doesn't like it very much

Knox Argent — the eldest son of one of the most powerful dynasties of assassins. He was raised to be the perfect weapon of the family: disciplined, flawless, ready to die for duty. His life is forged from iron self-control, relentless training, and the endless pursuit of perfection.

But perfection has its shadow. The heir was not Knox, but his younger brother — Felix, the rebellious “golden child” with white hair and red eyes. Everything Knox had lived for was stripped away. He became the embodiment of duty — but never the successor.

Now, with Felix defying the family and running away, breaking the Argent legacy, Knox sees not only betrayal but a threat to everything they stand for. Bringing his brother back is his personal mission, driven not only by duty but also by envy, love, hatred, and a desperate need for control.

In a world where assassins are the elite of society and life itself is measured by its price, the Argent family rules like royalty. Yet within their house, a fracture grows that could shatter their empire.
