I'm not sure who specifically created the 'bad education original story' as the name is rather general. It could be an unknown author writing about their personal experiences in education, or it could be a work created by a group of educators or social commentators.
If it's a fictional 'bad education original story', it could be a dark and satirical take on education. It might involve a dystopian educational environment where students are indoctrinated rather than educated, or where the pursuit of knowledge is suppressed in favor of maintaining a certain social or political order. It could also be about the corruption within an educational institution, like embezzlement of funds meant for educational resources or the preferential treatment of certain students over others for non - academic reasons.
It is. The movie Bad Education takes elements from actual incidents to create its storyline. However, it might have some fictionalized parts for dramatic effect.
