My Sin, Step-brother's Obsession

Kaelani's Pov:

I woke up later than usual, the sunlight already slipping through the curtains and warming my room. The digital clock on my nightstand flashed 9:47 a.m., reminding me how exhausted I had been the night before. I had stayed up for hours finishing extra work, determined to complete everything before the weekend. My body begged for more sleep, but I didn’t have the luxury of staying in bed.

Dragging myself up, I hurried into the shower. The cold water helped wake me faster than coffee ever could. After brushing my teeth and throwing on a pair of ripped jeans, a loose cream sweater, and white sneakers, I grabbed my phone and bag before rushing out of the apartment. I skipped breakfast because I already had plans with my two best friends, Seraphina and Alessia.

The three of us had been inseparable since middle school. Somehow, despite our completely different personalities, we worked perfectly together. Seraphina was wild and unpredictable, Alessia was calm and responsible, and I was usually stuck somewhere in between. I headed toward Gia’s Caffè, the cozy little café owned by Alessia’s family. It had become our safe place over the years. The smell of freshly brewed coffee and warm pastries always greeted customers before the bell above the door even stopped ringing. Alessia’s mother adored us and usually allowed us to occupy the corner sofa for hours without complaining, even during busy mornings.

As soon as I stepped inside, I spotted our usual place near the large window. Alessia was already there, sitting with a steaming cup of coffee in front of her while scrolling through her phone. “You’re finally here,” she said dramatically as I walked over. I laughed softly, leaning down to hug her before dropping onto the sofa beside her. Alessia shook her head with amusement. “She’s late as always.” “Yeah, she is,” I replied with a smile, already knowing exactly which friend we were talking about. That's when Fina came in the cafe.

Alessia's Pov:

I already ordered breakfast,” I said, leaning back into the sofa with a satisfied smile, watching the two of them settle in like they always did—like nothing in the world could ever truly separate us. “After we eat, I think we should go to your boutique, Kae, and pick up those dresses yours truly made for us.” Kaelani looked up at me, and I caught that faint smile she always tried to hide. She never really realized it, but there was something about her presence that made everything feel steady, even when life around us wasn’t. She had always been that way—quietly constant, like a thread holding something far bigger together without ever asking for credit. Me, Essia—Alessia Rowen.

Fina—Seraphina Vale. And Kae—Kaelani Voss. Three names that somehow always existed in the same sentence, the same memories, the same life chapters. People used to joke that we were an odd combination, like pieces from completely different puzzles that somehow still fit. But to me, we never felt mismatched. We just… balanced each other. Our dreams were never the same. In fact, if you looked at us separately, you’d probably never guess we would stay this close for so long.

Seraphina, Kaelani, and I were all built differently, shaped differently, pulled toward entirely different worlds. But somehow, we never drifted apart. Even when life tried. My family name carried weight in places I never asked for. My father was a businessman—sharp, disciplined, always thinking in numbers, deals, and expansion. My mother, on the other hand, built warmth instead of walls. She owned coffee shops scattered across the country, each one carrying her quiet signature of comfort and familiarity. People always assumed I would choose one of them. Business or hospitality. Something predictable. Something expected. I had two obvious paths laid out in front of me. And I chose neither. Instead, I chose a third path—one that didn’t come with instructions or guarantees. I chose modeling. It wasn’t something I stumbled into by accident. I started young, earlier than most people even know what direction their lives are taking.

At first, it was small opportunities—local shoots, small campaigns, fashion shows that barely made headlines. I remember how surreal it felt the first time I saw my face printed in a magazine, even if it was just a regional feature. It felt like stepping into a version of myself I hadn’t fully met yet. But I didn’t stop. I learned quickly that modeling wasn’t just about being seen—it was about presence, discipline, control, and understanding how to turn silence into impact. And I had support. Real support. My parents didn’t understand everything about the industry, but they never held me back from it either. I had sponsors who believed in my potential before I fully understood it myself. Slowly, everything started aligning in a way that felt both overwhelming and strangely natural. And now, at twenty-two, I was one of the top models in the country. Sometimes, even saying it in my head felt unreal. Not because I doubted it—but because I still remembered the girl who used to stand in front of her mirror practicing runway walks in a room that was too small for her dreams.

And then there was Fina. Seraphina Vale—though I rarely called her that unless I was teasing her. To me, she was always Fina. She had always been the most creative soul among us, even when we were children. While other kids played or followed instructions, Fina was building something with her hands. Beads, wires, scraps of metal—anything she could turn into something beautiful. Jewellery wasn’t just a hobby for her. It was instinct. A language she understood better than words. I still remember how she used to sit on the floor with tiny tools scattered around her, completely lost in her own world, designing pieces that looked far more expensive than anything a child should’ve been capable of creating.

And somehow, without even trying, those designs started gaining attention. First from friends, then from small communities, and eventually from people outside our world entirely. Her pieces would go viral before “viral” even felt like a normal thing to say. And now her brand—Vera Seraph—was one of the most respected jewellery names in the industry. I had always thought the name suited her perfectly. Elegant, sharp, a little mysterious. Just like her designs. She created pieces that didn’t scream for attention but somehow demanded it anyway. There was power in her subtlety, something people didn’t forget easily. Fina herself didn’t change much over the years, even with success. She was still unpredictable, still sharp-tongued when she wanted to be, still laughing at the most unexpected moments. But when she worked, there was a calm intensity to her that even I respected. It was like watching someone speak directly to metal and stone and somehow make them obey.

And then there was Kaelani. Kae. Kaelani Voss had always been different in a way that was hard to explain without making it sound like an understatement. If Fina created jewellery that felt like poetry, Kaelani created dresses that felt like entire stories. Not just outfits—stories. She never copied trends, never followed what was already out there. She started from scratch every single time, like every piece she made had to justify its own existence. Even when we were younger, she would design her own clothes for school events, parties, even casual days.

But what stood out most wasn’t just her talent—it was how naturally it came to her. Like she didn’t think about it in steps. She just saw something in her mind and brought it into reality with almost unsettling ease. And the strange part? It wasn’t just her own wardrobe. Mine and Fina’s outfits were often hers too. I still remember our prom night. Everyone else was wearing designer dresses from big brands, all beautiful in t
