Ta-da! A legendary mom who was a delinquent teenager goes to school to take it all! In a grey world of children marked with wounds, they are the mirrors of adults. Other main characters here are teenagers. Like the lyrics of a popular song children sing, the world is full of lies, and the school has become a prison without bars. Children do anything by fair means or foul for grades, deceive teachers by claiming parental authority, extort money from friends, and engage in violence. However, the world of such children is drawn here as it is, but the focus will be on the distorted portraits of adults that it reflects like a mirror. We should consider what a good adult is through the two faces of a mother who becomes a scary knife before corruption but a warm kitchen knife to children who are in despair for affection.
