I watched this drama 2 times and never get tired. When I first watched it in 2013 I cried like a baby, but I thought some things about the Korean education were exaggerated. But after living in Korea for 2 years, I realized this is real. This drama tells REAL stuff that happens to real people. Studying from day to night, pressure, greedy parents, depression and anxiety, young people without dreams....They literally don't have life. This hits me so much. I recommend this so much to people who want to understand better some issues in Korean society (that I really wish it could change through time...) . Highly recommend it to everyone.
