Fear Flew Away Like a Feather – Written by Shin Sun-jae, Illustrated by Yang Jeong-a Just like adults, children experience a wide range of emotions—joy, sadness, embarrassment, anger, fear, and more. But sometimes they don't quite understand what these feelings are. A child might slam a door or blush without knowing whether it's because they're sad, embarrassed, or angry. Understanding one's own emotions is important. Just as we learn the names and functions of body parts, giving names to our feelings helps us accurately recognize our emotional state. Once children understand what emotion they're feeling, it becomes much easier for them to know how to express it and how to cope with it. The Isum Emotions Series is designed to help children look within their own hearts and grow into mature, empathetic individuals who are considerate of others' feelings. Each book includes scientific information about why we feel various emotions and how our bodies react to them. With imaginative illustrations and delightful stories, the series examines emotions from many different angles. The appendix also features advice from a psychiatric specialist, offering deeper insight into the world of emotions.
