To navigate family pressure and a strategic business marriage, a cold, domineering billionaire recruits an ordinary young woman for a "sham marriage"—a mutually beneficial arrangement. She assumes it is merely a temporary performance, and he is firmly convinced that his emotions will remain under control. Yet, as they live side-by-side and test one another, desire and genuine feeling begin to blur the lines, while the secrets hidden behind their lies gradually come to light. As the contract nears its end and the truth closes in, the two must choose between their interests and their love—could this make-believe marriage evolve into a real, inescapable romance?
