Is this ever going to be updated or is it another abandonment by the author?

Chapter1: The proposal
The sound of traffic filtered through the frosted windows of Aria Monroe's tiny floral shop in Brooklyn, mingling with the faint scent of fresh lavender and crushed eucalyptus. Outside, New York City moved with its usual rhythm—people rushing somewhere, horns blaring, a steady pulse that never faltered. But inside Fleur & Ivy, time had a way of softening. Everything was quiet, fragrant, alive. Aria tucked a sprig of baby’s breath into a bridal bouquet, phone wedged between her shoulder and ear. “Zara, no, I swear if you wear that dress, you’ll outshine the bride. Again.” Laughter burst through the line, warm and crackling. “Isn’t that the point? I'm Kidding. Mostly. Aria, you’re the only person I know who makes a Monday morning feel so good.” Aria smiled faintly, smoothing a petal with her thumb. “It’s chaos here. Mrs. Leary’s anniversary bouquet order got delivered to a funeral parlor. I’m one call away from a Yelp meltdown.” “You live for the drama,” Zara teased. “Anyway,

Chapter 2: The hidden groom
The chapel was too quiet.Not solemn or sacred, just… empty. Heavy with tension instead of reverence.Aria stood at the entrance, clutching her bouquet so tightly that a thorn from one of the roses pierced her thumb. She didn’t even flinch. Her heart beat too loudly in her chest, drowning out the pain, the soft murmur of the guests, the sound of organ keys that hadn’t been touched yet.The veil felt like a curtain of iron draped over her head. She couldn’t breathe through the lace. The dress—borrowed, too long in the sleeves, tight at the waist—felt like it belonged to someone else’s life. And maybe it did.This wasn’t her story. Not really.This was her grandmother’s.Our blood is old, Aria, Nana had whispered just two days ago from the hospital bed, IV lines running along her frail arms. You come from a legacy, a promise sealed generations ago. If we lose that connection, we lose everything. He’s the only one who can keep our family standing.Aria hadn’t asked for his name.She hadn

Chapter3: The ice house
The drive from the chapel to Damian’s estate was steeped in silence so loud it rang in her ears. Outside the tinted car windows, the New York cityscape bled into suburbia and then into something else entirely—massive iron gates, manicured gardens, and a mansion that looked like it belonged to an empire, not a single man. The estate was located in the upper East side, Manhattan. It reminded Aria of those ancient palaces in European films—elegant, expensive, cold. Like the man who owned it. Damian hadn’t spoken a word since the ceremony. Not during the brief reception. Not during the drive. Not even as the staff greeted them at the entrance with tight smiles and murmured congratulations that sounded more like condolences. He simply walked ahead of her, his steps sharp, his back stiff beneath the fine cut of his designer suit. Aria followed. This was her life now. Inside, the house was cathedral-like: all white marble, chrome fixtures, and echoing silence. There were no family ph

Chapter 4: The rules of war
The morning sun filtered through the gauzy curtains, casting golden light across the breakfast table set for two. Silverware glinted, the scent of fresh coffee lingered in the air, and Aria sat quietly, buttering a croissant as if she hadn’t stepped into a cold war disguised as a marriage. Damian sat across from her, unreadable behind his espresso cup. His dark suit was crisp, his tie immaculate, his hair a little tousled from the rush of the morning—but his eyes weren’t on his phone or the newspaper. They were on her. Lingering. Assessing. She wore a soft blush blouse tucked into high-waisted linen trousers, her long hair loosely tied at the nape of her neck. No makeup, except for a soft rose lip balm. Her skin glowed with a kind of quiet defiance, and there was a graceful elegance in her stillness. Her beauty wasn’t the loud kind. It whispered. Soft curves. Intelligent eyes. A mouth that looked like it was made to argue and kiss in equal measure. She made him feel what he

Chapter 5: Meet the bodyguard
Aria woke with a strange stillness hanging in the air. The side of the bed where Damian usually slept was rumpled, but when she reached out, the sheets were cold. He had been gone for hours. She sat up slowly, brushing her tangled hair from her face. Sunlight streamed through the tall windows of the bedroom, illuminating the elegant molding and muted tones of the walls. For a moment, she let herself forget where she was. Then the memory of yesterday—the rules, the tension, the locked door with Elena engraved on the plate—came rushing back like an icy wave. She climbed out of bed and made her way to the en-suite bathroom. After a long, hot shower and dressing in a soft floral dress that flowed just pat her mid thigh, she stepped into nude sandals and applied light makeup. She might be trapped in a cold marriage, but she refused to look like it. The scent of eggs and freshly brewed coffee led her downstairs. She paused at the foot of the grand staircase, took a breath, and then enter

chapter 6: The gala
Morning sunlight filtered through the tall curtains of the breakfast room, catching in the Crystal glasses. Aria sat at the far end of the long mahogany table, sipping her tea slowly. She had grown used to the awkward silences of this house—the oppressive stillness that clung to the air like invisible chains. Damian was already there, impeccably dressed in a dark suit, his usual scowl in place as he scrolled through his phone. She placed her cup down. “Good morning,” she said, her voice polite but flat. He didn’t look up. “Good morning. You are coming with me to a gala tonight .” Aria blinked. “Excuse me?” “You heard me,” he said casually, still scrolling. “There’s a charity gala at the Astoria Hotel. You’re my wife now. I need to introduce you to a few people. It's important you come.” Aria stared at him, then let out a humorless laugh. “You can't be serious Damian. You’re telling me this now? At breakfast? The same morning as the event?” “Yes.” “And where exactly am I s

chapter 7: The flower girl and the ice king
The cold night air hit Aria like a slap as she rushed out of the grand, glittering ballroom. Her heels clicked against the marble steps as she descended, chest rising and falling with a silent fury. She stood just outside the entrance, wrapped in shadows, the sound of the music fading behind her. Her hands trembled as she clutched her purse tighter, blinking rapidly to push back the sting in her eyes. What was that? What had she just witnessed? Damian. Selene. And a f**king kiss. The image scorched her mind again—Selene’s perfectly painted lips pressing against Damian’s like it meant nothing. Like she meant nothing. Inside, the mood in the ballroom shifted. Damian pulled back roughly from Selene, wiping his mouth as if her touch disgusted him. “What the hell do you think you're doing?” Selene smiled, unfazed. “Oh, come on, Damian. Don’t pretend you didn’t miss me. We both know this... whatever this marriage is, it’s not real.” His jaw clenched. “My marriage is none of y

Chapter 8: Storm night
Damian sat in his home office, the blue light of his laptop screen casting shadows on his brooding face. Numbers and contracts flashed before him, but nothing held his attention—not fully. No matter how many calls he took, how many emails he responded to, his thoughts kept trailing back to her. Aria. Damn her. She wasn’t supposed to get under his skin. She wasn’t supposed to occupy his mind or soften the fortress around his heart. Not after what happened with Elena. The memory of his sister's tear-streaked face, the scandal that broke her spirit— and her death. He clenched his jaw. Aria had started that nightmare. And now, she was in his house. His bed. His life. A soft knock came on the door. “Sir Damian,” the housekeeper said gently, peeking in. “Dinner is ready.” He gave a stiff nod and stood, adjusting his sleeves as he walked out. The dining room was quiet, dimly lit, and Aria sat already, a plate of food untouched before her. She wore a simple sundress, her dark cur

chapter 9: The photo album
Monday morning crept in quietly, with a pale gray light filtering through the curtains. Aria reached across the bed instinctively, but her hand met cold sheets. Damian was gone. She sighed and pulled herself up. The lingering warmth from the night before had disappeared—not just from the bed, but from the air around her too. When she walked downstairs, she found Damian already seated at the long dining table, coffee in one hand, phone in the other. But what surprised her more was the man seated across from him—Jaxon. Jaxon looked up at her with the same blank expression he’d worn the first day they met, offering no greeting or smile. Damian didn’t even glance in her direction. "Good morning," she said, her voice even. Damian didn’t answer. Jaxon nodded, just once, before stabbing at his eggs like they were his enemy. Aria sat, pouring herself some tea. "Wow," she muttered. "So much warmth and hospitality in one room. It’s almost suffocating." Damian’s jaw clenched, but he

Chapter 10: The beginning of doubt
Two weeks had passed since Aria discovered the photo of her cousin Amelia in Elena Voss’ room, and not a day went by without the image haunting her. The more she tried to ignore it, the more the questions gnawed at her. How did Amelia know Elena? And why did Amelia disappear shortly after Elena’s tragic death? That morning, sunlight streamed into the bedroom as Aria stirred awake. Damian was already gone, likely buried in his usual sea of early meetings. She dressed quickly in a short floral gown that stopped at her mid-thigh—practical, she thought, for a warm Monday morning—and headed downstairs. Damian was already seated at the dining table with his coffee, flipping through his tablet. He looked up when she walked in, but his eyes lingered a beat too long. “Good morning,” Aria said, taking her seat. “Morning,” he replied curtly, then added, “Jaxon won’t be going with you today. I need him at the office. Another guard, Mikhail will follow you.” “That’s fine,” she answered, r
