A movie with three children.

It's about a boy and two girls who spend a long holiday in a huge forest and show their reality with games close to reality. Actors are underage children, but they show jealousy, ambition, abnormal love, possessiveness, arrogance and confusion so thoroughly that they can't continue. It is obviously an adult world, but the children rush in without hesitation. Finally, Eva was stabbed to death by Martin's dagger. It's just a game during the long vacation. The love between the king and queen, the jealousy and inability of the fallen concubine to resist, and abuse have become the only source of happiness, punishment and the way to freedom. Finally, the arrogant queen finally cried helplessly in the cruel and fearful reality, and her long blond hair was messy, snuggling up to the girl who played the bullied role in the game. The repeated appearance of that German shepherd dog is always accompanied by a strange vocal music, and fear suddenly attacks the whole body.
