The Billionaire’s Untamed Obsession

Elín Demánsdóttir’s POV:

Just a minute ago, I was genuinely terrified for my safety, certain that the exhaustion of the last six days had finally unhinged me. But the moment I looked up into Zonrik Zartholm’s piercing, glacial eyes, I realized I had been overthinking.

The concern I had imagined was non-existent. Instead, I heard Zonrik say in a tone vibrating with pure, unadulterated disgust, "How many days has it been since you stepped into a shower? I can smell the sanctuary from here. It’s a sour, clinical stench."

I knew he was telling the truth. For the past week, every ounce of my attention had been sacrificed to the spreadsheets, the mountain resort development data, and the legal parameters of the Haven Sanctuary. I hadn't left this office. But the visceral expression of loathing on Zonrik’s face still sliced through my pride.

"I'm going home to shower," I snapped, slamming my laptop shut. I couldn't stand the way he looked at me, like I was a diseased specimen from my own clinic.

"The city council hearing starts at nine o’clock. We leave the building at half-past eight. Are you certain you can navigate Hvalfjörður and return within ninety minutes?" His voice was a cold, stern lash from behind me.

I stopped in my tracks and looked back. "Do I have to attend the hearing as well?"

This was a high-stakes land development auction. Usually, only the titans of Zartholm Global and their predatory legal teams were allowed in the room. Seeing the genuine confusion on my face, Zonrik crossed his arms, his expensive suit jacket straining against his shoulders.

"You are the one who corrected the environmental impact surveys and the land-grading calculations," he explained with a terrifyingly controlled patience. "If the council asks about the 'sentimental' anomalies in the data—the nesting grounds or the drainage pipes—you are the one who will answer. I won't have my time wasted by a subordinate who doesn't know the difference between a fox den and a sinkhole."

"Understood," I muttered, looking at the clock.

It was seven o'clock in the morning. It took nearly an hour to get from the city center to my cottage near Hvalfjörður, let alone the time to scrub the smell of failure off my skin. I would never make it back. Zonrik looked down at the Patek Philippe on his wrist, his jaw tightening.

"I am going to print the finalized budget and the site plans. Go into the lounge and use the shower there. Just ensure you are out of my office before the executive staff arrives. I won't have rumors of a disheveled veterinarian living in my quarters."

"Fine," I whispered, too tired to fight.

After he swept out of the room, I walked into the private lounge tucked into the corner of the Zartholm Sky Residence. It was a secret, masculine sanctuary—minimalist, dark, and smelling faintly of his sandalwood cologne. There was a single bed, a desk, and a bathroom that looked more like a spa.

I stripped off my grime-streaked clothes and stepped into the shower. The hot water felt like a miracle against my aching muscles. I stayed too long, letting the steam fill my lungs until the world felt soft again. When I stepped out, I realized I hadn't brought a change of clothes. My old ones were damp and smelled of the office.

In a daze of fatigue, I found a crisp, white dress shirt in his wardrobe. It was far too big, the hem reaching my mid-thighs, but it was clean. It smelled like him—sharp, expensive, and intimidating.

I looked at the clock. It wasn't even eight yet. Just ten minutes, I told myself, crawling onto the small bed. I'll just close my eyes for ten minutes.

I slept so deeply it felt like drowning. I didn't wake up until a hand clamped onto my shoulder and physically hauled me upright. My eyes snapped open, and I found myself staring into the ferocious, dark gaze of Zonrik Zartholm.

"What are you doing? Do you have any concept of time?" He looked like he wanted to throttle me.

I glanced at the wall clock. My heart plummeted. It was 8:20 AM. We had ten minutes before we had to be downstairs. I grabbed my tangled hair in a panic, my mind racing. "I'm sorry! I didn't mean to—it was just supposed to be a nap!"

"And why," Zonrik asked, his voice dropping to a dangerous, low vibrato, "are you wearing my shirt?"

I looked down. I was indeed wearing his custom-tailored white shirt, the sleeves rolled up several times. I felt my face heat up. I was a mess, a disaster, and I was currently half-dressed in the clothes of the man who held my sanctuary’s life in his hands.

"My executive assistant, Alma, is already at her desk in the outer office," Zonrik said, his eyes raking over me with an intensity that felt like a brand. "How exactly do you plan on leaving my private suite without causing a scandal that will reach my father by noon?"

The thought of Mack Zartholm Sr. hearing about this made my blood run cold. I grabbed Zonrik’s arm, my fingers digging into his sleeve. "What do we do? You have to think of something!"

Zonrik’s POV:

I looked down at Elín’s hand on my arm. She looked small in my shirt, her eyes wide and clouded with sleep, her lips still slightly parted from her sudden awakening. For a fleeting second, the cold professionalism I used as armor felt heavy.

"Change your clothes immediately," I ordered, pulling my arm away. "In five minutes, I will send Alma to the records room. You will leave the office, take the service elevator, and meet me in the car in the basement. Do not be late, Elín. Not by a single second."

"I won't," she promised, already reaching for her discarded suit.

I waited in the back of the Bentley, the silence of the car filled only with the rhythmic tapping of my fingers on the leather armrest. When the door finally opened and Elín slid in, smelling of my own soap and looking pale but professional, I felt a strange, unwelcome surge of relief.

As Kasper pulled the car into the morning traffic of the Reykjavík–Copenhagen Corridor, I opened the file. I was focused, my mind a steel trap, but I could feel Elín’s eyes on me from across the carriage.

"What are you looking at?" I asked without lifting my gaze from the land-acquisition data.

"Nothing," she said quickly, looking out the window. "I'm just... worried about the plan. If the city council sees the discrepancy in the coastal erosion figures..."

"They won't," I interrupted, closing the folder. "I’ve reviewed your corrections. They are sound. Your logic regarding the natural drainage of the Hvalfjörður basin is... impressive."

Elín looked stunned. "You checked the entire report in two hours? That’s hundreds of pages of environmental data and geological surveys."

Kasper, my driver, caught my eye in the rearview mirror and chuckled. "Miss Demánsdóttir, you clearly don't know who you're dealing with. Mr. Zartholm graduated top of his class at Cambridge. He has a Master’s in Finance and Real Estate Development from the University of Texas at Austin. He passed his professional licensure exams before he was twenty-five. He doesn't just read reports; he dissects them."

Elín’s POV:

I looked at Zonrik with a new sense of wary admiration. I had always assumed he was just another "rich second generation" brat who had inherited his father’s empire without breaking a sweat. I didn't expect him to be a Cambridge-educated strategist with a mind like a computer.

"You passed the CPA and development boards by twenty-five?" I asked, my voice small.

I had spent my life dreaming of getting my senior veterinary certifications, but I had been too busy just trying to keep the sanctuary’s head above water to finish the final exams. I felt a pang of envy, and perhaps a flicker of respect.

"As long as you possess the discipline and the focus," Zonrik said, his voice returning to that arrogant, detached hum, "even someone with average talent can pass those tests. It isn't a miracle, Elín. It’s math."

The admiration I felt vanished instantly. The man was insufferable. I turned my head away, staring at the grey Icelandic morning. The silence in the car stretched out, heavy and uncomfortable.

After a few minutes, I felt his gaze on me. I checked my reflection in the window. My hair was coiled tightly, my professional suit was buttoned to the chin, and my golden earrings were in place. I looked like a consultant, not a veterinarian who had just slept in her boss’s bed.

"You didn't eat," Zonrik said suddenly.

I was taken aback. "I... what?"

"You've been awake for twenty-four hours. You haven't had breakfast. Are you hungry?"

"I'm fine," I said, my pride bristling. "I don't need—"

Gurgle.

My stomach betrayed me with a loud, hollow growl that echoed in the quiet Bentley. I felt the heat rush to my face. I looked down at my lap, wishing the floor of the car would open up and swallow me whole.

Zonrik didn't laugh. He simply reached into a compartment and tossed a wrapped sandwich onto my lap. "We have five minutes before we reach the council chambers. Eat it quickly. I won't have your stomach interrupting my opening statement."

I wanted to throw it back at him, but my hunger was a physical ache. I tore open the wrapper and began to eat. It was a simple chicken and pesto sandwich, but it tasted like a feast. Halfway through, the dry bread caught in my throat. I began to cough, my chest tightening.

Kasper immediately handed a bottle of water back to me. "Here you go, Miss Demánsdóttir."

I gulped the water down, gasping as the blockage cleared. "Thank you, Kasper," I whispered, glancing at Zonrik. He was already back to his papers, his face a mask of indifference. The wicked capitalist, I thought bitterly. He wouldn't even offer a drop of water if I were dying right in front of him.

The hearing was a battlefield. The room was packed with suit-clad executives from rival firms, all vying for the development rights to the corridor. I was called forward to answer three technical questions about the sanctuary’s impact on the local water table. I felt Zonrik’s eyes on me as I spoke. Every time I faltered, I looked at him, and the sheer, cold confidence in his expression gave me the strength to push through.

When the council retired to deliberate, I sat in the corridor, my hands trembling. If we lost, Mack Sr. would blame me. Zonrik would fire me. And the Haven Sanctuary would be gone.

Ten minutes later, the doors opened. Zonrik was the last to walk out. His face was a mask of stone, his lips pressed into a thin, hard line.

My heart sank. We lost.

"Mr. Zartholm?" I whispered, walking up to him. "The result?"

"Let's go," he said, turning toward the elevator without looking at me.

I followed him in my high heels, my heart breaking for the animals I’d have to relocate. I didn't dare speak. The elevator arrived, and we stood in the back. It was crowded—men in heavy coats pressing in on us. To avoid being crushed, I had to turn my back to the crowd, my chest practically pressed against the cold metal wall of the elevator.

Zonrik stood directly behind me, his large frame acting as a shield against the press of the crowd. I could feel the heat of his body, the scent of his sandalwood cologne wrapping around me.

"Why don't you ask?" he murmured, his voice vibrating against the back of my neck. "Don't you care about the fate of your little empire?"

I squeezed my eyes shut. "I'm afraid of the answer, Mr. Zartholm. I don't want to hear that I failed."

"You didn't fail, Elín," he said, and I could hear the faint, rare hint of a smile in his voice. "We won the bid. The Hvalfjörður corridor belongs to Zartholm Global."

I spun around, nearly hitting my head on the wall. "What? We won? Then why do you look like you’re at a funeral?"

"Because winning is the expectation," he said, staring down at me. "But I suppose... for you, it is cause for celebration."

I felt a surge of joy so intense I almost hugged him. "I pray every day for the sanctuary to stay safe, Mr. Zartholm. I want it to be the strongest refuge in the universe."

"The universe?" He arched a dark eyebrow. "Your ambition is expanding, Elín."

As the elevator doors opened, the crowd surged forward. I was pushed back, my heels slipping, but Zonrik’s hand shot out, catching me by the waist and pulling me flush against his hard chest. For a long, breathless second, we just stared at each other.

"Don't fall yet," he whispered, his eyes dark and unreadable. "The real war hasn't even begun."
