His Vengeful Contract: Ruining My Ex

Chapter 1

The towering glass facade of Thorne & Associates gleamed under the twilight sky, a monument to corporate ambition. Elena Rostova stood in the grand lobby, adjusting her grip on a chilled bottle of vintage Dom Pérignon and a velvet-wrapped box. Inside the box was a custom-engraved Montblanc pen, a gift for her fiancé.

"Elena! You're here late," a cheerful voice called out.

Elena turned to see Sarah, the night receptionist, beaming at her from behind the marble desk.

"I couldn't wait until tomorrow," Elena said, offering a warm but exhausted smile. "I heard the board made their decision an hour ago. Did Marcus get the Senior Partner promotion?"

"He sure did," Sarah said, clapping her hands together. "The whole executive floor was buzzing. His presentation on the Azure Resort project completely blew the investors away. They said the structural designs were the most brilliant thing they'd seen in a decade."

Elena's chest tightened with a complex mixture of pride and quiet resentment. *My designs,* she thought. *Those were my late nights, my sketches, my mathematical breakdowns.* But she pushed the bitterness down. It was for their future.

"He's still up there?" Elena asked.

"Yes, up in his new corner office on the fiftieth floor," Sarah replied, winking. "He told me he was reviewing some final contracts with Miss Sterling, but I'm sure he'd love a surprise visit from his beautiful fiancée."

"How can I sleep when the fate of Rostova Architecture hangs by a thread?" her grandfather's gravelly voice replied, thick with a Russian accent and heavy with fatigue. "Did Marcus secure the promotion?"

"He did," Elena said, keeping her voice steady despite the anxiety knotting her stomach. "Sarah just confirmed it. He's Senior Partner."

A heavy sigh of relief echoed through the speaker. "Thank God. Elena, my sweet girl... I hate that you are giving him your genius. You should be the lead architect here, saving our family's firm with your name on the blueprints, not ghost-designing in the shadows for a man like Marcus Thorne."

"We talked about this," Elena murmured, watching the floor numbers climb. "Marcus promised that once he made Senior Partner, he would inject a massive capital investment into our firm. His new status will give him the leverage to route the biggest supplier contracts to us. We just need to hold on until the wedding."

"I do not trust him, Elena. A man who steals his bride's glory is a man who will steal her soul."

"He's not stealing it. I gave it to him," Elena said firmly, though the words tasted like ash. "It's a partnership. Tomorrow is our engagement gala. Once he publicly
