The older sisters in the movie are all very cruel and aggressive, they always consider themselves as the older siblings in the family and bully their timid and gentle younger brothers. Being scolded and criticized is something the younger brothers often have to endure, but there is something much more terrifying than that, which is serving the sexual needs of the sisters, like sex slaves. The sisters dictate that when they say lie down, you lie down, when they say get up, you get up, not daring to go against their will. It is true that having older sisters can be tough, not like what people usually think.
