Every month on the final Sunday, our family convenes for a traditional lunch—a ritual my mother established after I moved out for university. Years later, despite my demanding career and independent apartment, I rarely make it home. Yet this particular Sunday morning changes everything when I meet him: a powerful billionaire whose possessive nature and magnetic charm blur the lines between business and desire. What begins as a calculated contract marriage evolves into something far more dangerous—an addiction neither of us can resist. In this dark romance, possession becomes passion, and a marriage of convenience transforms into an all-consuming obsession that neither wealth nor willpower can break.
