This book presents four stories set in "Zero School," a place for people who lack empathy. It explores the understanding and practice of empathy, a fundamental aspect of communication, through themes like dreams, hobbies, memories, and curiosity. As the protagonists, initially rigid and closed off, gradually soften and open up emotionally, the story beautifully captures their emotional growth. The illustrations delicately portray their changing feelings, ultimately stirring the readers' hearts. Though these characters start at zero, the book offers readers a glimpse of their boundless potential for growth.
