What is the ugly side of Korea culture?

I think Korean education. I think Korean education is so coercive.
Western education has more liberty than Korean education. Korea's high school students study very hard at night in school. So lots of students are reluctant to study.

University is important in Korea. So lots of high schools are studied for university.
Some schools are reluctant to study arts, sports students. I think that is bad. So I think Korean education will change.
Now education is not very bad. But Korean education is will more liberty.
Than lots of students are interested in education.
