THE BILLIONAIRE’S OBSESSION のすべてのチャプター: チャプター 1 - チャプター 10

Sienna didn’t sleep that night. Not even a little. Her body may have been wrapped in the luxurious sheets of the guest room Damien had offered, but her mind refused to rest. It spun in anxious circles, replaying his words like a haunting melody. You belong to me now. What had she done? She stared at the dark ceiling until morning broke. Then she rose, showered, and stepped into the clothes his assistant had left for her—designer labels she couldn’t even pronounce. The soft silk blouse hugged her curves too perfectly. The pencil skirt clung to her hips like it had been tailored by the devil himself. When she finally walked into the penthouse’s dining room, Damien was already seated at the long glass table, sipping espresso as if he hadn’t just altered the course of her life the night before. “Sleep well?” he asked without looking up from his tablet. “I didn’t sleep.” “I didn’t expect you to.” Sienna sat across from him, her posture stiff. “What’s next?” Damien placed the tablet

Sienna stood in front of the large floor-to-ceiling windows of Damien’s penthouse, gazing out at the sprawling city below. The lights glittered in the distance, but to her, it all felt so far away. The vast expanse of the skyline mirrored the chasm growing between her and Damien—an invisible gulf that was slowly widening the more she learned about the life he led. Damien had been unusually quiet since they left the boardroom, and Sienna had noticed the change in his demeanor. He was no longer the confident, assertive man who had effortlessly dominated the room. Instead, he was more withdrawn, almost contemplative, as though he were waiting for something. But what? Sienna turned from the window and found him sitting on the couch, his posture relaxed but his eyes sharp, as if he were analyzing every move she made. The tension in the room was palpable, like a simmering pot that was just on the verge of boiling over. She took a step forward, trying to break the silence. “Damien, about

The ballroom was a masterpiece of opulence. Glittering chandeliers spilled golden light over marble floors, and soft classical music danced in the air like silk. Men in tailored suits and women in flowing gowns moved like chess pieces across the polished floor—every smile, every word, every gesture carefully curated. This was Damien’s world. And tonight, Sienna was being thrown right into the center of it. She stood beside Damien, dressed in an elegant black gown he had picked for her. It fit her perfectly, hugging her curves and leaving her shoulders bare. Around her neck sat a diamond necklace that probably cost more than her entire college tuition. It wasn’t just jewelry. It was armor. A declaration. “You look stunning,” Damien whispered into her ear as they stepped further into the room. His hand rested lightly on her lower back, guiding her forward—but it felt more like control than comfort. Sienna forced a smile, reminding herself to breathe. “Why do I feel like I’m about to

It started with a phone call. Sienna’s phone buzzed just past midnight. She was half-asleep, curled beneath her sheets, her thoughts still tangled in the memory of Damien’s touch. Her heart skipped when she saw his name flash on the screen. Damien. She hesitated for only a second before answering. His voice was low and velvety. Come outside. She sat up, confused. What? Come. Now. Then the line went dead. Moments later, Sienna was standing on the curb in her silk robe, arms folded against the chill in the air. Damien’s black car pulled up silently, its windows tinted, the engine purring like a predator waiting to strike. She slid in, heart thudding. “Didn’t know you were the type for late-night drives,” she said, trying to sound casual. “I’m not,” Damien replied. “But I had a meeting. I want you to see something.” They drove in silence, the city slowly fading behind them. The lights grew sparse. The roads quieter. After nearly twenty minutes, the car turned down a private dri

Sienna stormed into her apartment, slamming the door behind her with a force that reverberated through the walls. Her heart pounded in her chest, each beat a reminder of how badly things had gone. The anger surged, burning hotter with every passing second. She didn’t know whether to scream, cry, or punch something. The sharp click of her heels on the marble floor did nothing to quiet the noise in her head. Damien’s face, his eyes—those cold, calculating eyes—flashed in her mind, over and over. How could he? How could he betray her trust like that? It wasn’t just the files—no, that was only the tip of the iceberg. The betrayal was in the way he looked at her when she confronted him. The way he tried to justify it. The way he dismissed her feelings, as if they didn’t matter in the grand scheme of his world. She wasn’t just another employee to him. She wasn’t just another pawn in his ruthless game. She was supposed to be more than that. She tossed her bag onto the couch and stood in th
