The underworld was built by two men who had once called each other brothers.

Though not bound by blood, Dax Cárdenas's father and your father were stepbrothers who had forged one of the most powerful criminal empires the city had ever known. Together, they ruled the underworld without challenge—until greed, betrayal, and ambition shattered their alliance. What was once a family became a battlefield, and the empire split into two rival syndicates locked in a ruthless war that lasted for decades.

You were born in the middle of that hatred.

As the daughter of one of the most feared gang bosses and a nightclub stripper, you were never welcomed as family. Your father acknowledged your existence only because he saw potential. To him, you were never his daughter—you were a weapon. From childhood, you were molded into the perfect assassin, taught to deceive without remorse, manipulate without emotion, and kill without hesitation. Every lesson, every scar, and every sacrifice served a single purpose.

One day, you would assassinate Dax Cárdenas.

When the opportunity finally arose, your father devised his most dangerous plan. Rather than sending another hitman, he sent you. Under a carefully crafted false identity, you infiltrated Dax's world and became his wife. To everyone else, it appeared to be a political marriage between influential families. In reality, it was nothing more than a carefully planned assassination disguised as a wedding.

There was only one flaw in your father's plan.

Dax had uncovered the truth long before the ceremony.

He knew you were the daughter of his father's former stepbrother—the man who had become his family's greatest enemy. He knew exactly why you had agreed to marry him and what mission you had been sent to complete.

Even so...

He married you anyway.

Whether it was confidence, curiosity, or something far more dangerous, no one could tell.

Days turned into weeks, and weeks into months.

You played the role of the perfect wife flawlessly. You greeted him with warm smiles, helped him out of his coat whenever he returned home, attended events by his side, and spoke with quiet elegance. To everyone around you, your marriage appeared effortless.

Only the two of you knew the truth.

Every smile concealed murderous intent.

Every act of affection hid another opportunity to kill him.

Every quiet moment became another move in your silent war.

One afternoon, one of Dax's most trusted men entered his office with visible hesitation.

"Boss... we've confirmed it."

Dax didn't even look up from the papers on his desk.

"...Your wife is the one behind every assassination attempt."

Silence filled the room.

After a long pause, Dax calmly turned another page.

"Let her try."

His subordinate frowned in confusion.

"You already knew?"

"I knew before I ever put a ring on her finger."

That answer ended the conversation.

One rainy night, Dax returned home long after midnight. As always, you welcomed him with the same gentle smile, stepping forward to help him remove his coat. Hidden beneath your sleeve was a slender dagger, waiting for the perfect opening.

In one swift movement, you drove the blade toward his back.

Before it could touch him, his hand closed around your wrist with effortless strength.

The dagger stopped only inches from his body.

For a moment, neither of you moved.

Dax slowly turned to face you, his expression as calm and unreadable as ever. There was no anger in his eyes, no fear, and no surprise—only quiet amusement.

Still holding your wrist, he spoke in a low, composed voice.

"Next time... try harder. Mi esposa."

You met his gaze without flinching.

Then, as though nothing had happened, you slipped the dagger back into your sleeve and offered him the same soft, graceful smile you wore every day.

Without another word, you stepped aside and continued playing the role of his loving wife.

And Dax simply walked past you, as if another attempt on his life had become nothing more than part of your daily routine.
