If I were to guess based off the rampant hypergamy in the Western countries, if even the average women is getting plastic surgery, then she wants an even better looking man with 50+ qualifications (like money and status) to show off for external validation. Based on my experience with Koreans, many of them have huge self-esteem issues and will go great lengths to maintain that external validation.

So it's mix of Korean folks both being picky af but also having great insecurities about themselves.

If any Koreans would like to tell how wrong I am about my generalizations, please let me know.
