Mr Sinclair, your ex wife is a tomboy billionaire

The ache in my shoulders was a dull, heavy throbbing after a grueling day of running around, managing the estate, and handling the endless demands of the house. I was completely exhausted, but knowing Sebastian had been pulling late nights at the office made me push through my own fatigue. I had spent the last two hours slaving over a hot stove just to make sure he had a proper, fresh home-cooked meal. The staff at Sinclair Enterprises didn't stop me. They were entirely familiar with my face, offering respectful nods and bright smiles as I bypassed the reception desk and took the private elevator straight to the top floor. Clutching the warm lunch bag tightly against my chest, I walked down the quiet, carpeted hallway toward the grand double doors of the CEO's office. I didn't knock, wanting to surprise my husband. I pushed the heavy double doors open, but the warm greeting died instantly in my throat. I froze. There, right in front of me, was Sebastian and a lady I recognized all too well—Chloe Vance, his ex. Her legs were parted wide over his lap, her hands resting comfortably on his shoulders. The sound of the door opening made them both immediately turn their heads toward me. Chloe’s eyes widened, and she instantly jumped off his lap, scrambling to pull down her short skirt. "Oh my goodness! Videl, I am so, so sorry!" Chloe stammered, her voice dripping with a fake, breathless apology. She clutched her chest dramatically. "It’s not what it looks like, I swear! I only came by so we could go over the details regarding our companies' business agreement. We had just finished up and I stood up to leave, but I suddenly got so dizzy that I completely lost my balance and fell right onto his lap! Please don't misunderstand, it was a total accident!" I stared at Chloe. Her expression looked completely guilty and panicked, but deep in her eyes, I saw what was truly there: a flash of smug triumph. She was marking her territory, and she was enjoying every second of it. My eyes instantly snapped away from her and locked onto my husband. There was no panic on Sebastian's face. No flush of shame on his neck. His dark eyes didn't even blink as he calmly leaned back in his leather chair, adjusting the silver cuffs of his shirt. He looked at me with absolute indifference, his expression freezing over with cold irritation because I had interrupted them. "What are you doing here?" he asked flatly, his voice completely calm. The question felt like a bucket of ice water pouring over my head, freezing the last remnants of my warmth. He had just been caught with his ex straddling his lap, and instead of an explanation, he was demanding to know why I was in his space. The initial urge to scream, to tear Chloe away from him, and to demand answers suddenly withered away. Looking at his cold, unbothered mask, I realized something that made my heart go entirely numb: he didn't care enough to even pretend to be guilty. A heavy, quiet calm settled over me. "I came to bring you lunch," I said, my voice shockingly steady, devoid of the tears threatening to choke me. I took a few measured steps forward, completely ignoring Chloe’s presence as I placed the warm lunch bag neatly on the edge of his pristine desk. "But it seems I came at the wrong time." I looked him dead in the eye, refusing to give him the satisfaction of seeing me break. "I'll take my leave." Without waiting for a response, and without giving Chloe a single glance, I turned on my heel. With my head held high and my posture perfectly straight, I walked out of the office, closing the heavy double doors softly behind me. I didn’t let a single tear fall until I was safely locked inside my car in the corporate parking lot. The steering wheel blurred through my vision as the crushing weight of what I had just witnessed pressed down on my chest. I had spent years being the perfect, dutiful wife, only to be made to feel like an intruder in my own husband's life. My phone buzzed against the passenger seat, shattering the heavy silence. I wiped my face and picked it up. It was an unknown number, but the text message left no doubt about who was on the other end. Unknown: “You looked so pathetic standing there, Videl. I almost felt sorry for you. But let’s be real—you’ve always known you were just a placeholder. A temporary substitute keeping his bed warm until I got tired of being away. Sebastian never loved you. He never will. Save yourself the embarrassment and hand over your position.” A bitter smile touched my lips. Did she really think she could unhinge me this easily? I tapped the screen and sent a reply that would slice right through her pride: Videl: “If I am just a cheap substitute, then why hasn't Sebastian divorced me yet to marry you? He knows you're here. Yet, I am still the one wearing his ring. Maybe he just thinks you're better suited to be a mistress.” The reply from Chloe came almost instantly, the three dots flashing aggressively. My words had clearly struck a nerve. Unknown: “You are being way too arrogant, Videl. Enjoy that ring while you can, because I promise you it won't be on your finger much longer. You have no idea what Sebastian and I share. Don't say I didn't warn you when you're left with absolutely nothing.” I didn’t give her the satisfaction of another response. I simply blocked the number, tossed the phone away, and drove straight back to the villa. Let her drown in her own insecurity and threats. By the time evening arrived, the heavy, suffocating pain had settled into a dull, numb acceptance. I didn't lock myself in the bedroom to cry. Instead, I showered, changed into comfortable lounge clothes, and lay down on the bed, blankly staring at the ceiling. Around 8:00 PM, the heavy bedroom door opened. Sebastian walked in, loosening his silk tie, his dark eyes instantly scanning the room until they landed on me. I didn't jump up to greet him. I didn't look at him with tear-stained eyes. "You're back," I said flatly, my voice entirely devoid of emotion. Sebastian paused, his brow furrowing slightly at my lack of a reaction. "Yeah," he replied, his voice gruff as he tossed his jacket onto a nearby chair. "Mm." I gave a low, uninterested hum and closed my eyes. Silence stretched through the room. He lingered near the edge of the bed, clearing his throat before he finally spoke up, his tone stiff. "About this afternoon," Sebastian started, his voice tightly controlled. "Chloe has a severe inner ear condition that causes sudden bouts of vertigo. That’s why she lost her balance and fell. There is absolutely nothing going on between us." A wave of quiet shock washed over me—not because of the ridiculous excuse, but because Sebastian was actually explaining himself. In all our years of marriage, he had never felt the need to justify his actions to me. "I understand," I said softly. A flash of visible relief washed over Sebastian’s face. He clearly thought my quiet compliance meant I was brushing everything off, accepting his pathetic excuse like the dutiful, submissive wife I had always been. Before I even knew what was happening, he crawled onto the mattress. His strong arms wrapped tightly around my waist, pulling my back flush against his chest. I could feel his warm breath brushing against my skin as he leaned in close to my ear. "Tomorrow is Mother's birthday gala," he said, his voice dropping into a lower, more intimate murmur. "The family expects us to arrive together. I'll come back from the office to pick you up so we can leave straight from here." "I know," I murmured. He buried his face into the crook of my neck, inhaling deeply. "You smell good," he murmured, his voice dropping into a low, husky growl. His lips pressed against my neck, sending a familiar, electric shiver straight down my spine. His mouth trailed hot, demanding kisses up my jawline, deliberately teasing me until he finally turned my face and captured my lips. The kiss was intense, a familiar fire that usually made me melt completely. Trapped in his embrace, my treacherous body reacted out of pure habit, my heart rate spiking as his heavy body hovered over mine, deepening the intimacy on the sheets. For a split second, the warmth almost made me forget the cold office. Ring! Ring! The sharp, loud blare of his phone shattered the atmosphere. Sebastian froze against my lips. He pulled back, irritation crossing his features as he reached into his pocket. As he pulled the phone out, the screen lit up the dim room. The caller ID was clear as day: Chloe. Sebastian didn't hesitate. He didn't even look at me to apologize. He immediately slid the screen to answer the call, pressing it to his ear. "Hello?" he said, his voice instantly sharpening. He listened for a mere two seconds before his face turned pale. "What? Hold on, I'm coming right now!" He threw the covers off, bolting out of the bed as if the mattress was on fire. Without a single backward glance at his wife lying flushed on the sheets, he grabbed his jacket from the chair and rushed out of the room, slamming the front door a few moments later. I stayed exactly where I was, staring blankly up at the ceiling. Slowly, the corners of my mouth began to twitch. My face widened into a smile, and then a bitter, breathless laugh escaped my throat. I laughed out loud into the empty room, but the sound was hollow, suffocated by the hot tears that finally poured down the sides of my face. Just a single phone call. One call from her, and he would abandon his wife on their marriage bed without a second thought. The laughter died, replaced by a cold, unshakeable clarity. I was done. I was so, so tired of this humiliating cycle. I sat up, wiping the tears from my face with a finality that rooted deep in my chest. I walked over to my vanity, flipped open my laptop, and pulled up a secure messaging portal to my lawyer. With steady, unblinking eyes, I typed out the words that would end my marriage: Arthur, draft the divorce papers for Sebastian and me immediately. I want everything ready for signature by tomorrow morning. No delays, and keep it strictly confidential. I didn't hesitate for a single second. I hit send. The screen blinked, confirming the message was delivered.
