Taelin Oh, about her work (THANK YOU, for your response!):
This animation is about Original Fairy Tales.
Further more, it's talking about people's dark side.
I believe the theory that human nature is fundamentally evil.
Children always act based on their instinct for everythings.
So children can catch dark and chaotic side from the fairy tales easily even though it's already revised.
Also, fairy tales're created by Adults who grown up from children.
although adults want to write down something beautiful and pretty for children, they might can add some weired or disorded parts unconsciously.
