My Ex's Regret: Married To His Enemy

For eight years, I was the Falcone mafia's top fixer and the Don's secret fiancée, taking bullets to keep his syndicate alive.

But when my mother was crashing from heart failure, he refused to authorize her lifesaving surgery.

I dropped to my knees in the middle of the crowded ballroom, begging him to make the call.

Instead, Kieran didn't even flinch. He sat there meticulously folding a paper bird for his new favorite, Elena.

"You are causing a scene, Sienna," he scolded me coldly. "And you completely forgot to pick up Elena's custom gown today. I am not rewarding your tantrums."

He then publicly stripped me of my executive rank, gave my hard-earned Underboss title to Elena, and made a show of praising her-while the vintage diamond ring he had chosen in her favorite style still sat on my finger.

I had died on the operating table three times to build his empire, yet he was willing to let my mother die over a delayed dress.

The desperation in my gut congealed into a block of ice, and my lingering love completely burned away.

I took off the ring and walked straight out of the Falcone estate into the freezing night.

Outside, the Matriarch of his deadliest rival was waiting in an armored SUV.

"My clinic can save her," she said smoothly. "But you know the price."

I didn't even hesitate.

"I will marry your son."

Chapter 1

Sienna POV:

The light from the crystal chandeliers in the Falcone ballroom was a physical weight, pressing down until one's eyes ached. It caught in the facets of champagne flutes and the polished teeth of underworld elites, a low, dangerous hum of conversation filling the air. I stood in the shadows near the grand staircase, my phone pressed so tightly to my ear that my knuckles ached.

"Sienna," Serena's voice cracked through the receiver, choked with hysterical sobs. "Mom is crashing. The doctors say her heart is failing. They need authorization for the experimental bypass, but the clinic won't proceed without the Don's financial clearance. She is dying, Sienna!"

The murmur of conversation, the clinking of glasses-it all receded, replaced by the low, insistent thrum of blood in my ears. "I am getting him right now," I breathed, my voice a tremor in the sudden quiet of my own head. "Hold on."

I shoved through knots of Capos and politicians, my eyes frantically searching the opulent room. I found Kieran sitting at the head of the VIP velvet booth. He wasn't discussing syndicate business. He was leaning in, his broad shoulders angled protectively toward Elena. She was laughing softly, her delicate hand resting on his forearm.

I rushed forward, my heels sinking into the thick carpet. "Kieran," I gasped, stopping right in front of the table. My face was bloodless, my chest heaving. "Kieran, I need you. Mom is crashing. She's dying. I need your clearance for the Romano clinic right now."

Kieran didn't even flinch. He slowly finished his sip of bourbon, his dark eyes sliding toward me with a chilling disinterest. He picked up a thick cocktail napkin and, with an excruciating slowness, began folding the corners, his fingers meticulously crafting a small paper bird.

"You are causing a scene, Sienna," he said, his voice a low, reprimanding drawl over the swell of the classical music. "And you completely forgot to pick up Elena's custom gown from the tailor this afternoon. She had to wear this off-the-rack dress because of your negligence."

I stared at him, the logic of his words failing to connect in my brain. "My mother is dying," I repeated, my voice raw and cracking. I dropped to my knees, right there in the middle of the VIP section. "Please. Just make the call. I will do whatever you want later."

Elena shifted uncomfortably, looking down at me with wide, innocent eyes. "Kieran, maybe you should-"

"No," Kieran cut her off smoothly, placing the finished paper bird on the table. He didn't look at me. "I am not rewarding insubordination and tantrums. You will learn to prioritize the Family over your personal melodrama. Go handle your mess quietly."

He turned back to Elena, completely and utterly ignoring my existence. The woman who had bled for him for eight years, who had kept his books clean and his smuggling routes open, was begging for her mother's life, and he was folding paper birds for another woman.

I looked down at my trembling hand. The heavy diamond engagement ring on my finger caught the chandelier's light. It was a vintage cut-Elena's favorite style, I suddenly realized with a sickening lurch of my stomach. He hadn't even bought a ring for me; he had simply purchased the ring he once intended for her.

The desperation did not so much evaporate as it did congeal, turning to a block of ice in my gut. I looked down at the ring, at the facets of the diamond. They were just pieces of cut glass. The warmth of the metal against my skin was gone, leaving only the cold, dead weight of it. I slid the ring off my finger and let it fall onto the velvet booth. I stood up slowly. I didn't say another word. I turned my back on the man I had loved for eight years and walked straight out of the ballroom, out of the estate, and into the freezing night air.

A sleek, black armored SUV was idling near the gates. The window rolled down, revealing the sharp, calculating eyes of the Romano Matriarch-the Falcone Family's greatest enemy.

"I heard about your mother, child," the Matriarch said smoothly. "My clinic can save her. But you know the price of Romano blood."

I took one last look at the Falcone mansion, a glittering cage receding in the night.

"I will marry your son."

It took me exactly three seconds to answer. The door of the armored SUV closed with the dense, final sound of a vault being sealed. I was inside.

The Romano Matriarch gave a single, curt nod. She tapped the glass partition, and the driver sped away from the Falcone estate, leaving my old life behind in the dust.

Within the hour, I was standing outside the sterile, unforgiving glare of an operating room in the heavily guarded Romano private clinic. The Matriarch had mobilized her surgical team the moment I'd said yes. Above the double doors, their porthole windows dark, the red light clicked on.

Serena ran down the hallway, her face blotchy and stained with tears. She threw her arms around my neck.

"You did it," Serena sobbed into my shoulder. "Kieran actually pulled through. He used his connections. He saved Mom."

I pulled my sister back, gripping her trembling shoulders, and looked her dead in the eye.

"Kieran did not do this," I said, my voice completely flat. "Kieran is no longer our family. Do not ever say his name to me again."

Serena stared at me in shock. She opened her mouth to ask questions, but I held up my hand.

"The wedding date remains the same," I told her. "But the groom has been replaced. I am marrying Enzo Romano."

As Serena covered her mouth with her hands, I turned my back to the operating room doors. I stared at the blank white wall opposite, tracing a crack in the plaster with my eyes until it burned a permanent, jagged line onto my retina.

Three days later, the doctors transferred my mother to a secure recovery suite. She was stable. The Romano medical team had pulled her back from the edge of death.

I left the clinic and drove straight to the Falcone Syndicate's headquarters, a monolith of smoked glass and steel that devoured the morning sun.

The moment I walked into the lobby, the men straightened up. Capos and soldiers nodded at me with deep respect. I was their top fixer. I was the woman who had kept them alive when the old Don died.

"Congratulations, Boss," a scarred Capo said as I stepped into the elevator. "We heard the news."

I ignored him, stepping out onto the executive floor. My team was gathered near my office, their faces bright with expectant smiles. They thought I was finally getting the official Underboss title I had earned with my own blood years ago.

The twin doors of carved mahogany, their brass handles worn smooth by the hands of powerful men, swung open, and Kieran walked out. He wore a dark, tailored suit, and his sheer physical presence seemed to alter the density of the air. He halted as if he'd walked into a wall of glass when he saw me.

"You are late," Kieran said, his voice a sharp crack down the hallway.

I searched his face for some trace of the man I had known, but found only the familiar architecture of his features, now inhabited by a stranger. No anger. No heartbreak. Just a cold, empty distance.

"You have been absent for three days without my explicit permission," Kieran said loudly, his voice pitched for every soldier on the floor to hear. "You abandoned your post."

"My mother was dying," I said simply.

"Everyone has personal problems, Sienna," Kieran snapped. "We are the Mafia. The Family comes first. You let your emotions cloud your judgment."

He took a step closer to me, looking down at me from his towering height.

"Effective immediately, you are stripped of your executive privileges," Kieran announced. "You are demoted back to Capo. Your syndicate shares are being transferred."

The hallway went dead silent. The men around me shifted uncomfortably, their eyes finding sudden interest in the scuffs on their shoes.

Elena walked out of the conference room right behind him. She was wearing a soft pink dress, a splash of pastel fragility among the hardened killers in the room.

"Elena will be taking over as the new Underboss," Kieran said. He placed a possessive hand on her lower back. "She has the clear head this Family needs right now."

Elena smiled at the men. It was a sweet, innocent smile. A sour wave of bile rose in my throat, hot and acrid.

"Hi everyone," she said softly. "I am still learning about all these investments and things. I hope you will all be patient with me."

Kieran watched her with undisguised admiration.

"Sienna," Kieran said, turning his cold attention back to me. "You will organize a formal welcoming ceremony for Elena tonight. It will be your first task under her command."

I looked at Elena. I thought about the nights I had spent in freezing warehouses with a gun in my hand. I thought about the three times my heart had stopped on an operating table to keep this very syndicate from getting torn apart by a federal RICO case.

I felt a dull, agonizing ache in my chest as I watched this woman effortlessly steal my crown.

I took a slow, steadying breath. I turned my head sharply and looked my Don dead in the eye.

"No," I said.

Kieran frowned, a muscle knotting in his jaw. "Excuse me?"

"I resign," I said. My voice was steady and loud enough for the entire floor to hear. "I forfeit my oath. I am done."

Sienna POV

Kieran's features settled into a stillness that was more unsettling than any rage.

"You do not get to throw tantrums here, Sienna," he warned, his voice a low, dangerous rumble.

I did not answer him. I turned on my heel, walked straight into my private office, and the thick glass door clicked shut in its frame behind me. I sat at my desk and pulled up the encrypted syndicate network.

I typed out my formal resignation, bypassing standard channels to trigger the Omertà severance protocols. It meant I was walking away with nothing. No money. No protection.

I hit send.

Sixty seconds later, my computer screen flashed. The resignation was approved.

My desk phone rang immediately, the shrill, electronic summons cutting through the quiet. I picked it up.

"Elena is just a figurehead," Kieran said smoothly through the receiver. His tone was cold and authoritative. "She needs help managing the shadow investors. You know the accounts better than anyone."

I started opening my desk drawers, silently pulling out my personal files.

"Once you correct this attitude of yours, I will give you your rightful rank back," Kieran continued. He spoke to me like I was a disobedient child.

I tossed a stack of folders into a cardboard box, the heavy thud echoing in the quiet room.

"I am giving you exactly five minutes to retract that email," Kieran said, his voice dropping to a lethal whisper. "If you do not, I will enforce your exile. You will have nothing."

I stared at the darkened computer screen. I pictured him sitting in his massive office, arrogant and untouchable, fully believing I would crawl back to him.

I hung up the phone.

An exhaustion so profound it felt like a sickness settled in my bones, making each movement a negotiation against gravity. I spent the next few hours packing my operational files.

I carried my box downstairs to the exclusive underground restaurant on the ground floor. I needed food.

I walked past the host stand, but suddenly, a loud ringing filled my ears. The edges of my vision began to fray. My knees buckled.

I collapsed onto the hard marble floor, the impact jarring my bones.

Before consciousness could fully desert me, strong hands grabbed my shoulders. Someone lifted me off the ground, and the smell of expensive cologne and gun oil filled my nose.

"Drink this."

A glass was pressed to my lips, and I swallowed the sugary liquid automatically. Someone forced a piece of dark chocolate into my mouth, the sweetness shocking my system awake.

My vision slowly cleared. I was sitting in a plush leather booth. Kieran was leaning over me, his hands still gripping my arms with bruising intensity.

Elena was standing behind him, a flicker of irritation tightening the corners of her mouth.

I pushed Kieran's hands away. I sat up straight and wiped my mouth with the back of my hand.

"Thank you," I said coldly. "You can leave now."

Kieran did not move. Instead, he slid into the booth across from me. Elena hastily sat down next to him.

"We are not leaving," Kieran said, casually signaling a waiter. "Elena likes this specific table. It is the only one available."

He was not asking me to leave; he was commanding it, using her as the instrument of his authority.

"He knows all my favorite things," Elena said. She deliberately leaned her head against Kieran's shoulder, looking at me with a triumphant smile.

The food I had craved moments before turned to ash in my mouth. I picked up my glass and downed the rest of the sugary drink in silence.

Kieran reached into his tailored jacket, pulling out his black burner phone. He placed it dead center on the table between us, the soft clack of plastic against wood echoing like a gunshot.

It was a silent command. He was waiting for me to pick it up, call his office line, beg for forgiveness, and call off my resignation.

I looked at the phone. Then I looked up at Kieran, meeting his unwavering, arrogant gaze.

I reached out my hand, my fingers brushing the smooth casing as I picked up the black phone.

Kieran smirked, a dark, victorious curve of his lips.

I moved my hand to the right and released his phone into a pitcher of ice water on the table, watching the dark shape of it sink as his victorious expression went under with it.

Sienna POV

The phone sank to the bottom of the glass pitcher, a thin stream of silver bubbles rising to the surface.

Kieran stared at the water, his expression one of blank, uncomprehending shock, the arrogant smirk having vanished from his face.

"Loving someone makes you terrified of them getting hurt," I said, my voice eerily steady.

"That is why I never used ultimatums to force your hand for eight years. I was too afraid of cornering you."

I slid out of the booth and gathered the cardboard box, its bottom groaning under the weight of the files, the twine biting a sharp, red line into my fingers.

"But you never feared hurting me, Kieran," I said.

I turned and walked toward the exit.

Out of the corner of my eye, I saw Kieran abruptly stand up.

His jaw clenched tightly, and a hesitation crossed his dark eyes.

He took half a step forward. But he did not follow.

Over the next half-month, I meticulously handed over the Syndicate's illicit operations to the other Capos.

I made sure every smuggling route, every political bribe, and every hidden weapon stash was accounted for.

I owed the Famiglia that much.

Once my duties were fulfilled, I started packing my personal belongings out of the fortress-like penthouse I had shared with Kieran.

On the fourth day of moving, my new phone rang. It was him.

"Where are the quarterly reports?" Kieran barked into the receiver, his voice tight with fury.

"You are abandoning your post. You are throwing a fit over nothing. Get back to the office right now."

He had completely erased the fact that I had officially resigned.

His arrogant brain simply refused to process that I was actually leaving him.

A weariness that felt like it was woven into my marrow settled over me.

Without a word, I pressed the end call button.

I taped up the final cardboard box in the center of the living room just as the moving crew was hauling my furniture out the front door.

A sharp *ding* echoed from the private elevator. Kieran and Elena strolled into the penthouse.

Kieran was casually carrying two bags of expensive groceries, and they were laughing softly about something.

They looked like a normal, happy couple coming home to cook dinner, acting as if the hulking shapes of the moving vans parked at the curb did not exist.

Elena stopped in her tracks and looked at the stacked boxes.

"What is all this?" she asked, her voice a carefully constructed instrument of bewilderment.

Kieran briefly glanced at the boxes, pointedly refusing to look at me.

"Sienna is just clearing out the old for the new," Kieran said with a dismissive wave of his hand.

"She is preparing to be married out of this estate."

Elena sighed wistfully. She drifted over to the floor-to-ceiling windows and gazed out at the glittering city skyline.

"I always dreamed of being married from this very penthouse," Elena murmured softly.

"I wanted the white roses on the balcony."

Kieran set the groceries down on the marble island.

He walked up behind her and smiled, his reflection catching in the glass.

His typically cold eyes softened with a warm, genuine affection I hadn't seen in years.

My mind went completely blank.

*White roses on the balcony.*

That was the exact floral setup Kieran had ordered for our wedding.

I had always known, in some locked corner of my mind, that Kieran had never cared about the details of our Mafia wedding. The realization simply landed at last, in that sickening, heart-stopping moment.

He hadn't bothered to ask me what I wanted.

He had simply remembered Elena's fantasies from five years ago and lazily applied them to me.

A pain so sharp it felt structural, as if a rib had snapped and pierced a lung, stole the breath from my body.

I grabbed my heavy wool coat and walked past them in silence. I just needed to get out of this room, now airless and hostile.

"Watch out!" one of the movers suddenly yelled.

I snapped my head up.

One of the movers had lost his grip on a massive, solid marble bust from Kieran's office.

It was plummeting straight toward us.

He moved with the brutal economy of a trained killer. One arm hooked around Elena's waist, using her own momentum to swing her clear of the statue's descending path. He never once looked back at me. The marble crashed down where I stood, and I raised my hands too late-a useless, instinctive gesture. The impact was a dead, pulverizing weight that drove the air from my lungs. The marble burst on impact, its heavy, sharp fragments tearing through flesh and sinew.

Blood immediately poured down my trembling fingers, spattering in thick drops against the pristine hardwood floor.

The sight of my own torn skin was gruesome, terrifying, and a final, bloody testament to who Kieran truly loved.
