Are Koreans heavily in debt?

Excuse me, I'm quite curious about a matter. I've heard rumors that Koreans are heavily indebted. Is this really the case? If so, what are the main reasons behind this phenomenon? Are there any specific policies or measures being taken by the government to address this issue? Additionally, how does this debt situation affect the overall economy and the lifestyle of the average Korean? I would appreciate it if you could provide me with a detailed explanation.
