CRAVING THE FORBIDDEN BILLIONAIRE'S SIN

PROLOGUE – A NIGHT OF BLISS

If I were ever told that one crazy night could destroy everything I had built, I would have laughed out loud and poured myself another drink.

But that is the thing about chaos. It never knocks before coming in. It thrives on surprises.

That night, the city pulsed like it had heartbeats. I have never been in a place that crowded before. The night was thick with intentions. The stars glistered in the sky. I, Rain Hart, fresh off an overcrowded bus from an unknown town, a town that I had always wondered if it was even on the map. I stood at the edge of my new life. I made it. I was finally here, the great city of lights, fashion, and dreams that girls like me, and from where I was coming from, could not afford.

Tomorrow, my classes will begin at the globally recognized fashion school, owned by Katherine Knight. The Katherine Knight. The goddess of Haute couture. I had spent years stitching pieces of fabric together, day and night, watching this woman online, literally worshiping her and vowing that I would meet her. Now, it was happening.

But first, I wanted to celebrate my arrival and drink to a new chapter. It felt like the first thing to do. Like an opening ritual.

The bar smelled like whiskey, cigarette smoke, and bad choices. It was very loud and wild; the type of place where no one cared who you were or questioned you, only how long you could keep up. The music hammered through my chest as if trying to adjust my heartbeat. I didn't plan to drink much, but the atmosphere was electrifying and sucked me in. Someone handed me liquor, another handed me a dare, and before I knew it, I was dancing on top of a table.

Screaming.

Laughing.

Free.

The crowd applauded and cheered excitedly like I was their queen. My hair flew around, part of it covering my face, and the hem of my short red dress glittered under the neon lights. I felt like I was walking on clouds, and for the first time in my life, I wasn't the broke girl chasing dreams. I was living the dream.

And that was when I saw him.

He was drinking at the bar, black shirt buttoned halfway, expensive accessories, eyes like sin; calm, calculative, powerful, and watching me with the kind of concentration that made my skin tingle. Most men stared like they desired to own you. He looked at me like he already did.

I don't remember who made the first move, but I remember being pressed against him in the bathroom, laughter mixed with unclear whispers and moans. There was this dangerous aura around him, not just the way he looked, but that quiet confidence that said he was used to getting anything he wanted. And that night, of course, he wanted me. Every part of him said so clearly.

Everything after that was blurry, even the sound of my own pulse. We barely talked, no names, no stories. Just two strangers pretending the outside world didn't exist. Just living the moment in each other's arms.

When I woke up, the room was bathed in the early morning sun and the faint sound of traffic downstairs. My head ached badly, my lipstick was smudged, and my dress was hanging on an expensive chair that definitely wasn't mine. It took me a while to remember where I was.

He was still sleeping, partially covered with the white sheets, handsome, peaceful. I stood there for a while, studying his face. He did not look like the type of man I would ever meet in my life, let alone spend a night with. Everything about him was flashy but radiating secrets.

For a moment, I thought about waking him to say "thank you" or "goodbye." But something inside me quietly said that it was better this way. No awkward conversations. No reality check. No exchange of information. Just a random night that would vanish like smoke.

So I wore my gown, picked up my bag and heels, tiptoed across the marble floor, very careful not to wake him. I mistakenly kicked an empty bottle, and it rolled noisily on the floor until it was stopped by his clothes. I looked back, saw him turn in his sleep, and I slipped out before he opened his eyes, shutting the door as quietly as I could.

The long hall was littered with more doors than I could count and smelled like coffee and money. I took a deep breath, squared my shoulders, and whispered my favorite quote: Eyes on the goal. No distractions. Just dreams.

By the time I entered the street, the city had already enveloped last night. No trace of the night that welcomed me to New York. It was so bright that I squinted while trying to take it all in at once. Cars honked loudly, and people hurried past me, brushing my shoulders.

"Is everyone in New York in a rush?" I asked myself, and I melted into the crowd like nothing had happened. Just another hungover girl with messy hair, misplaced mascara, and a plan to change her life.

But as I caught my reflection in a coffee shop window, a girl stared back, a girl I didn't recognize. There was something new in her eyes, a spark, a danger, a secret.

I smiled at her.

"Welcome," I whispered to her, "to a fresh start."

If only I knew that life had a different agenda for me. If only I knew that the man I had left asleep in that hotel room wasn't finished with me yet. If only I knew that one night of freedom would become the most expensive mistake of my life.

Because the moment I walked through the gates of the fashion academy that morning, destiny, in its cruel, shiny heels, was already there waiting.

And it was wearing Katherine Knight's smile.

CHAPTER 1 - THE MORNING AFTER

That morning, covered with shaky nerves and sunshine, in front of the mirror in my tiny apartment, I applied concealer under my eyes to create the illusion of a well-rested face. My stomach tightened, my head pounded hard, and every blink brought flashes of last night: the neon lights, the laughter, the man. I shook it off. New city. New life. No space for regrets.

Orientation for freshers at the fashion institute would begin in two hours. I had waited for this all my life. I wasn't going to allow a silly one-night stand to spoil it. In a white blouse and tailored brown trousers, I looked professional; nothing like the girl from last night. I wore red lipstick and felt ready.

The campus looked like heaven. The air mixed with perfume and ambition. Students walked like they were on runways. Every corner screamed elegance; from the glass walls, shiny floors, to the banners reading THE KATHERINE KNIGHT COUTURE ACADEMY.

Reading her name made my heart flutter. Katherine Knight, the inspiration behind all my sketches. The reason I was here.

A lady with a clipboard gave me a student badge. "Rain Hart," she read. "Welcome to the academy. Your class is in Studio C."

Studio C looked unreal. Sewing machines glittered under chandeliers, mannequins stood elegantly, and huge inspiration boards covered the walls. Students were showing off their drawings and fabric selections.

I sat near the window, clutching my sketchbook. A petite redhead leaned over. "Nervous?"

"Afraid," I said with a small smile.

She grinned. "Same. I'm Lucy. From London."

"Rain. From, uh, nowhere special."

Before she could reply, the room went dead. Every head and eye turned toward the door.

She was here.

Katherine Knight entered like a slow-motion movie scene. Her presence filled the room. She wore a shiny black dress, her blond hair in a perfect bun. Her heels hit the marble floor like punctuation marks of power.

"Welcome, designers," her tone was calm but commanding. "You've earned your spot here. Let's see if you can keep it."

A ripple of nervous laughter swept through the room. Katherine smiled, but it wasn't warm. It was precise. Controlled. The type of smile that knew exactly how much power it wielded. She went to each desk, going through sketchbooks, murmuring comments. When she got to mine, my throat tightened.

I held my breath as she turned the pages of my portfolio. Her expression was unreadable. Then she looked at me. "Rain Hart," she said softly. "You sketch emotions. I can feel the story in your drawings."

My heart shook. "Thank you, ma'am."

She studied me curiously, "Where did you learn to sketch like this?"

"I practiced by drawing people in the streets back home."

Katherine smiled faintly. "Interesting. You capture the soul, not just the style. Fashion needs more of that."

She hovered for a few more seconds, then left. But I could still feel her eyes on me, like a bright light.

By the end of the session, my nerves were calm. Maybe I really did belong here. Maybe last night doesn't count.

Then Katherine spoke again, "I'll be taking one student as my personal assistant, to work closely with me, attend my meetings, and master the industry from the inside."

Every student straightened.

Katherine's eyes met mine. "Miss Hart, I would like that to be you."

I blinked. "Me?"

She nodded, smiling in that poised manner. "Your designs are deep. Consider it a challenge."

The class was staring, some with envy, others with curiosity.

"Thank you, ma'am," I stammered. "I won't disappoint you."

"I hope not," she said, turning toward the door. "My driver will bring you to my home this evening. We begin early tomorrow."

When she left, Lucy hugged me. "Rain! This is big!"

I smiled, dazed. "I can't believe it."

But as we left the class, an uneasy feeling crept into my mind.

Later that evening, the driver arrived, a tall man in a dark suit who barely spoke as he led me into a black car. The ride was quiet aside from the hum of the engine and my own thoughts spinning faster than the tires.

When we pulled up to the Knights' mansion, I froze. The place looked like a palace of gems, on a mountaintop. Every inch of it oozed wealth and power.

The front doors opened before I even reached them. Katherine stood inside, flawless as always, a glass of wine in her hand. "Welcome, Rain," she said smoothly. The smell of roses and luxury greeted my nose.

Katherine turned to me. "You'll stay in the east wing. My husband will be home shortly. I would like you to meet him before dinner. He is our school's major investor."

I nodded, still overwhelmed. "Of course, ma'am."

As we entered the grand living room, a deep masculine voice sent shivers down my spine.

Katherine smiled and turned toward it. "There he is."

A tall figure in a navy suit walked in, wearing the kind of presence that made everything stand still. I got dizzy.

It was him.

The man from the hotel room.

The stranger whose touch I still felt on my skin.

I couldn't move. My mouth was dry. He froze too, recognizing me, before sliding into practiced calm.

Katherine kissed him on the lips. "Darling, meet my new protégé," she said brightly. "Rain Hart."

He looked at me, eyes dangerously controlled. "Rain," he said, softly. "A pleasure."

I forced a smile, my heart beating so loudly I was sure they could hear it. "Likewise."

Our gazes locked. Something silent lingered between us, sweet and forbidden.

Katherine, unaware, turned to pour wine. "Rain will be a great fit."

"I'm sure she will," he whispered, still looking at me.

I swallowed hard, suddenly knowing how close I was to catastrophe. The air felt thick.

"Rain, breathe," I told myself.

Deep down, I knew that the night I thought I could forget had just followed me home.

CHAPTER 2 - THE MANSION OF MIRRORS

The driver had dropped my suitcase on the porch, leaving me alone in the biggest house I have ever seen. I went outside to pick it up.

Katherine Knight's voice cut through my thoughts, "Come, let me show you around."

We went through corridors decorated with portraits and gowns like a museum. My shoes sank into the posh white carpet. The Knight mansion felt alive. The shiny floors reflected the lights like water. My reflection on the mirrors that lined the hallways seemed to whisper, "You don't belong here." My simple dress looked embarrassingly off compared to the world of luxury around me.

As Katherine walked me through the mansion, I admired the books sorted by color, and even the air felt customized.

"Working closely with me needs discretion and discipline," she said as we passed a long aisle lined with art on the walls, "The fashion world isn't all glitter and glamour. It's a battlefield of ideas, and I like to stay on top."

I nodded, trying not to gape at a life-sized portrait of her wearing a crown of black feathers and a dazzling, long black dress. "I understand, ma'am."

She smiled slightly. "Good. No place for weakness. I reward loyalty."

Her words were heavy, like a promise and a warning entwined.

My room was twice the size of my old apartment, with white curtains that glittered in the soft light and a balcony displaying a beautiful aerial view of the city. A small mannequin stood in the corner, as if begging for my sketches.

"It's perfect," I said, my voice shaking.

"I'm glad you like it. Dinner will be ready soon. Freshen up and join us downstairs."

When she left, I sat on the bed, my heart spinning. How did I end up here? Yesterday I was just Rain from nowhere. Today I was living under the same roof as the most powerful fashion icon... and her billionaire husband.

The memory of him hit me like a wave. Adrian Knight. The man from the hotel. The man whose touch refused to leave my skin, no matter how hard I scrubbed.

I tried to steady my breathing. This was my dream, I reminded myself of what I was there to achieve under the wings of Katherine Knight. Nothing else counted. Whatever happened last night was a mistake; a secret buried deep under city lights.

But secrets have a way of following you.

When I entered the dining hall, the glow from the chandeliers beautified the crystal glasses. Katherine was already seated at the head of the table, elegant as ever. Adrian sat beside her, looking effortlessly magnetic in a tailored black suit.

His eyes found mine the second I walked in. For a moment, the world was reduced to just the two of us. His gaze wasn't soft or apologetic. It was electric, like we both remembered too much.

Katherine gestured gracefully. "Rain, come, sit."

I forced a smile and sat across from them, praying my shaking hands wouldn't betray me.

Dinner was amazing and terrifying. Katherine talked about fashion events coming up, celebrity clients, and an upcoming partnership with a Paris brand. Adrian barely spoke, but I could feel his attention on me every time I looked up.

"So, Rain," Katherine said suddenly. "What was your inspiration?"

I swallowed, "I grew up making clothes from scraps. It was the only thing that made me feel in charge of my world."

Her eyes softened briefly. "Good answer. Passion and pain often make the best designers."

Adrian finally spoke, his voice low and calm. "Katherine, you sure know how to pick them."

She smiled at him, but he wasn't looking at her. He was looking at me. My pulse was fast. The air between us was thick with something dangerous, something neither of us could name.

After dinner, Katherine's phone rang and interrupted my thoughts. She excused herself to take the call. "Rain, feel free to explore the gallery on the first floor," she said, "Adrian will show you the way."

My stomach tightened.

We walked through a dimly lit passageway, our footsteps echoing. The gallery was filled with images of Katherine on the runways, Katherine with presidents, Katherine at flashy events with Adrian, and Katherine holding award plaques.

"She likes to see herself everywhere," Adrian murmured.

I was startled. "She's... impressive."

"She is many things," he said, his eyes on one of the mirrors.

Then came the awkward silence. His voice softened. "You left without saying goodbye."

My heart stopped. "It was for the best. What happened was a mistake."

"Was it?" He came closer, "Because it is stuck in my head."

I stepped back, my vision getting blurry. "You're married."

He nodded slowly. "I know."

There was something in his expression: regret, desire, or maybe something darker.

"Let's forget it ever happened, please," I whispered.

He came close enough for me to feel his breath on my skin. "I've tried."

Before I could respond, Katherine's voice echoed from upstairs. "Adrian, darling, have you seen my tablet?"

He stepped back immediately, his face returning to calm perfection. "In your studio, I think."

I pretended to be admiring a painting, looking composed, but my heart was in turmoil.

A brightly smiling and elegant Katherine appeared minutes later, "Ah, found it! Rain, I hope you're settling in well. Feel at home."

"Yes, ma'am. It's... alluring here."

"Good." She slipped her hand into Adrian's arm, her diamond ring catching the light. "You'll start tomorrow at eight. Sleep well, Rain."

They walked away together, but Adrian looked back once, his eyes meeting mine in a mirror nearby. It was only for a second, but it was enough to take my breath away. As they disappeared down the hall, I stood alone, swallowed by a truth that I couldn't face yet. Because deep down, I already knew. In this house of glass and glory, nothing was as flawless as it appeared. And sooner or later, something was going to crack.
