Passive aggression hurts quietly, but deeply. It hides in innocent phrases, looks, and actions, leaving behind anxiety, a sense of guilt, and doubt. This book—an international bestseller in South Korea—is a honest and piercing conversation about how to protect yourself. Jeong Mun-jong, based on personal experience, knows what it’s like to endure in silence and then, at night, replay in your head, “How I should have answered.” The author will teach you to stand up for your boundaries and not let the offender use you. You’ll learn how to recognize passive aggression at the very beginning and how to stop it with dignity—without conflicts or tension, while preserving inner harmony.
