This book is based on campus violence. Many campus violence is invisible to us, but it actually exists in every school.
School violence includes not only physical injuries, but also psychological trauma.
Of course, in addition to violence, there are many warm things.
Most of the time, all we can do is work hard to become a better version of ourselves. Beauty and ugliness have their destiny, but there is no end to learning, and there are more possibilities in the future.
