Love after Marriage
Contract Marriage
She never meant to become his wife. Aria Hale had only stepped into the marriage registry to deliver her sister’s documents. Yet somehow, she walked out as the legal wife of Leon Mercer—the city’s most ruthless billionaire. One signature. One mistake. One furious husband determined to make her regret it. “You trapped me,” he growls, ice lacing every word. “You’ll pay for this.” But Aria isn’t who he thinks she is. She carries secrets he could never imagine—an identity carefully hidden, a fortune he never suspected, and a strength that refuses to break under his cruelty. He assumes she’s a gold-digger. She lets him believe it. When he insists she stay until the divorce is finalized, she agrees—but only because she has her own plans. And then he notices. The way she never begs. The subtle power in her laughter. The way other men glance at her… and how his chest tightens in ways he can’t explain. By the time the truth comes crashing down—when he finally discovers who she really is—it’s too late. Aria is gone. Now the hunter becomes the hunted. The billionaire married the wrong woman by mistake. And losing her will be his greatest regret.

The Accidental Bride
It never occurred to Aria Hale that her sister's wedding day would end with her own marriage license. Pushing through the glass doors of the New York City Marriage Bureau, she held the manila envelope to her chest. Immediately, chaos erupted: clerks yelling names, couples yelling over paperwork, and phones ringing nonstop. A bride in a discolored white gown was yelling at her groom about his mother while a baby cried close to the fountain.
Aria wanted to disappear—one job. Deliver the documents. Leave. Invisible, like always. "Next!" a clerk barked, waving impatiently from behind the scratched plexiglass. Aria stepped forward. "Hi, I'm here to—" "Name?" "I'm not—" "NAME?" "Aria Hale. I'm just delivering—"Ariana Hale!" Her stomach dropped.
"No, that's my sister. I'm Aria, not—" "You responded to the name. Good enough." The clerk shoved a clipboard through the slot. "Fill this out. Your groom's already twenty minutes late. If he doesn't show in ten, you forfeit your slot."
"But I'm not getting married!" Aria's voice cracked. The clerk finally glanced up, expression neutral. "Everyone's nervous, honey. Just breathe and sign when he arrives." Aria checked her phone. Nothing. No texts. No calls. Just a curt message from her sister: ARIANA: Emergency. Can't make it. Leave the papers. Thanks! No apology. No explanation. Just an order.
She typed and erased responses she would never send while her fingers lingered over the screen. After twenty-four years of being forgotten, invisible, and cleaning up other people's messes, she was rewarded with a room full of strangers who couldn't even pronounce her name correctly. The doors burst open.
Every head turned. A man walked in like a storm given human form. Broad shoulders, dark hair, grey eyes, sharp enough to pierce steel. Leon Mercer. Billionaire. CEO. The man her sister was supposed to marry.
He stopped in front of her. "You're late." Aria opened her mouth. Closed it. Wrong person. Wrong sister. Wrong everything. "Save it. Let's get this over with." He grabbed her elbow. Warm. Firm. Unyielding. Trapped. "Wait, you don't—" "Ariana Hale and Leon Mercer!" The clerk slid the papers across. "Sign now." Her hand shook. She looked down at the certificate. Aria Hale. Not Ariana. Not her sister. Her own name.
She froze. Her heart pounded in her chest. "Sir, I think—" "Think later. Sign now."
His Patek Philippe gleamed in the overhead light as he checked his watch. Aria's mind raced. Run? Scream? Call her parents? But who would believe her? Who would take her side when she had just signed the papers herself? Her hand moved on its own. Aria Hale.
The pen scratched across the page. The clerk stamped it with a heavy thump. "Congratulations. You're married." Time slowed. Every sound dulled. Leon's grey eyes lifted to hers. Cold. Furious. Ice. "You're not Ariana." "I tried to tell you—" "You signed." He held up the certificate. "Aria Hale."
With a low voice that cut like a knife through the chaos, he said, "You trapped me.". "You will regret this every day until I am free of you. Aria had a burning throat. She was on the verge of tears, but she held back.
Not here. Not now. "I didn't trap you. You didn't even look at what you were signing." He ignored her. Shoved the certificate into his jacket. His other hand gripped her wrist—not cruel, not gentle, just possessive. "You're coming with me," he said, phone pressed to his ear. "Lawyer. Meet me now." Outside, a black Mercedes waited.
The driver already held the door. Aria's mind raced. She could run. She could scream. She could call her family—but who would listen? Who would believe her? She looked at Leon. The fury simmered beneath his controlled exterior. The man hated her. And legally, she was now his wife. The door closed.
She felt the smooth, cold leather against her back. She took a sharp breath. "Go. The harsh, blinding sunlight hit her face. She caught a glimpse of herself in the window's tint. Aria Hale. Not Ariana. Nobody's second choice. She had recently unintentionally wed a billionaire who hated her. She also didn't know how she would survive what was about to happen.

Aria could not sleep.Surrounded by papers, phone logs, and digital forensics software, Sophia's contact delivered at three a.m., Aria spent the night in Leon's penthouse office—the one he'd told her never to visit.She was still wearing the emerald necklace.A reminder. A weapon. A promise.By sunrise, she had proof.The messages Vanessa showed were fake. The metadata was altered. The phone number listed as Aria's belonged to a burner phone registered in New Jersey, where Ariana had been hiding for the past month.But it was the financial records that made Aria's blood run cold.Ariana had been systematically draining Aria's trust fund since she turned eighteen. Small transfers at first, then larger ones. Hidden behind shell companies and fake investment accounts. Over seven years, she'd stolen nearly $40 million.Forty million dollars that could have changed Aria's life. That could have saved her from student loans, from roommates, from wearing thrift store clothes while her sister

The Metropolitan Museum's Great Hall glittered like something out of a fairy tale.Aria stood at the entrance beside Leon, her hand tucked into the crook of his arm, and tried to remember how to breathe. Crystal chandeliers cast prisms of light across marble floors. Women in designer gowns dripped with jewelry. Men in tuxedos talked business over champagne that probably cost more than her monthly rent.This was Leon's world.And tonight, she had to convince everyone it was hers, too."You are shaking," Leon murmured, his thumb stroking her hand where it rested on his arm. "Breathe.""There are at least three hundred people in there." Aria's voice came out thin. "All of them are judging. Whispering. Waiting for me to fail.""Let them wait." Leon turned to face her fully, his hands cupping her face. "Look at me."She did.His gray eyes were firm, unwavering, rooted in the maelstrom."You are Aria Mercer," he firmly declared. "My wife. Like everyone else, you belong here. And everyone in

Leon's face was inches from Aria's when she awoke.With a yelp, she sprang back and almost fell off the bed. "What are you doing?""Watching you sleep." She probably had drool drying on her chin, while he looked maddeningly perfect—fresh-pressed white shirt, dark tailored pants, not a single hair out of place."You snore.""I do not!""You absolutely do. It's cute." He sat on the edge of her bed like he'd done it a hundred times before. "My mother will be here in two hours. We need to talk strategy."Aria rubbed her eyes, her brain still foggy. "Strategy? For meeting your mother?""My mother is not a person. She is a tactical operation."Leon gave her a cup of coffee, brewed to her exact preferences. When had he learned that? "With just one chat, Catherine Mercer has ruined three of my past relationships. She is cold and cunning, and she will take advantage of every weakness you have.""You are really selling this meeting.""I am preparing you for what is to come." His hands found her

Aria was elbow-deep in work emails when the penthouse elevator chimed.She looked up from her laptop, confused. Leon wasn't supposed to be back until seven, and Sophia had left hours ago. The security system should have alerted her if someone was coming up.The elevator doors opened.A tiny woman dressed in a Chanel suit stepped out, followed by two men carrying luggages.She had white hair styled in an elegant up-do, her sharp blue eyes scanning everywhere, and the kind of posture that suggested she'd been trained to walk with books on her head. Diamonds glittered at her throat and wrists—not flashy, just casually worth more than most people's houses."Well," the woman said, her voice crisp and carrying. "You must be the girl who finally trapped my grandson."Aria's mouth fell open. "I—what—I didn't trap—""Relax, dear. I'm teasing." The woman waved the luggage men toward one of the guest rooms. "I'm Elena Mercer. Leon's grandmother. And you're Aria, the accidental wife who has my gr
