How much is considered a lot of money in South Korea?

Excuse me, I'm a bit curious about the financial situation in South Korea. I've heard that the cost of living and income levels vary quite a bit compared to other countries. So, I was wondering, how much money would be considered a significant amount in South Korea? Would it be a certain number of Korean Won, or is it more relative to the average income or cost of living? I'm just trying to get a better understanding of the financial landscape there. Thank you for your time.
