This is a book about bullying and anti-bullying. It can't teach you how to ruin the lives of bullies, but it can tell you as objectively and impartially as possible what bullying is and what true anti-bullying is. And everyone can also notice that bullying itself is not a simple and crude problem.
We are all angels, descended into the world, but our soft wings cannot resist the sharp malice. Maybe some of us will choose to become angels again and let go, and some of us will reluctantly pull out our wings, but some of us will grow steel wings, crush all thorns and malicious intentions, and soar in the blue sky.
May you grow wings of steel and become your beautiful, powerful and kind self.
In the end, we will find that the best revenge is that you are not assimilated, but become stronger.
