What you are attached to is very important in Korea. Sometimes somebody is not defined as a private person but as a member of a certain group in Korea. In some respects, it is nonsense because I am what I am. Actually many Korean young people recently want to be judged by their personality but so far Korean people think them as a member of a certain group.
For example, the powerful evaluation standard used by Korean society is an academic clique. Many western countries are in the same situation but in Korea it is more serious. So, clearly it is a big problem and many people tried to solve this problem and is trying but it is not hopeful because many Korean people think education to be the only resource that improves and leads Korea to an advanced country. It is means that they think the competition of students for attending a top university to be only the solution of improvement for Korea.
In the other domains, a situation is the same like an academic clique. Maybe we can assume that this situation is from the extreme situation of Korea with high desire for the growth of economy in spite of low natural resources. So, as long as you live in Korea, you can't escape the question "Where are you attached?"
