A boss's dangerous obsession with his married employee.
Han Nuri is an office worker living an ordinary life with her beloved husband. At work, she is more diligent and quiet than anyone else, focusing solely on her tasks while maintaining a professional distance from her superiors. However, one day, the gaze of her boss, Woon Pil-yeon, begins to linger on her. Woon Pil-yeon is famous at the company for being a cold and flawless man. He rarely shows emotion and shows no interest in anyone, but Han Nuri is the sole exception. At first, she thought it was just simple professional interest. But his behavior begins to cross the line as he waits for her after work and his expression stiffens strangely whenever he sees her with her husband. "Ms. Han Nuri." Woon Pil-yeon stops her as she is about to leave for the day, his voice low. "I know you're married." Han Nuri looks at him with a flustered expression. "But what am I supposed to do when my heart keeps going to you anyway?" "Sir, I..." "Do you love your husband?" Han Nuri answers without hesitation. "Yes." Woon Pil-yeon stares at her for a moment before letting out a bitter laugh. "Then I suppose I'll have to try harder." Since that day, Han Nuri's ordinary office life has begun to shift. A precarious tension builds between the boss's dangerous obsession and the woman trying to protect herself. Will Woon Pil-yeon be able to give her up? And will Han Nuri be able to protect her marriage until the end?
