I recommend. It is about the South Korean educational system (its teaching quality and vices) and the misuse of social networks. It denounces of the unbearable pressure inflicted on teenagers by their parents, society and, in the end, by themselves. All for a place at the best colleges. With three periods of daily studies: morning at school; afternoon at the prep course and night at home. Suffering from sleep deprivation and lack of leisure time. Mothers suffer similar pressure from society which they reproduce on their children and husbands. It also depitcs the malevolent use of social networks and digital parasites, which destroy careers, families and lives under their steamroller. Their posts end up being reproduced in the media, amplifying their devastating effects. It starts with a very successful workaholic prep course teacher.
