Excellent manga that tells a powerful, often heartbreaking, story about bullying, in its various forms from perpetrator to bystander, and its lasting effects. When a young man bullied a classmate in elementary school because she couldn‘t hear, he changed her life as well as his. Now in high school he regrets what he, and others did, and hopes to make things right. Other themes include suicidal thoughts, forgiveness, jealousy, & guilt. Great read.
