Isabelle Alcantara had her life planned out: take over her father’s business empire and finally get her childhood best friend, Gio Sarmiento, to notice she’s the one for him. But when her father dies suddenly, his last will and testament drops a bomb that shatters her world. To inherit the controlling 51% stake of Alcantara Holdings and save the company from her ruthless grandmother, Isabelle must marry within thirty days. But the groom isn’t the sweet, charming Gio. It’s his older brother. Nathan Sarmiento. Ten years older. Cold. Calculated. The terrified employees call him "The Dragon," and he’s the only man who has ever intimidated Isabelle. It was supposed to be a simple business arrangement: 1. Keep the marriage a secret. 2. Stay married for two years. 3. Strictly business. No feelings. No intimacy. But living in Nathan’s sleek BGC penthouse changes everything. Behind the closed doors of the master suite, the cold-hearted CEO is possessive, intense, and dangerously seductive. As late nights at the office turn into heated moments under his desk, the line between "fake wife" and "real obsession" begins to blur. The contract says two years. But their hearts might not last two weeks.
