Who is the most expensive paid actor in Korea?

Could you tell me who holds the title of the most expensive paid actor in Korea? I'm genuinely curious to know who commands the highest paychecks in the Korean film and television industry. Are there any specific actors or actresses who stand out in terms of their earnings, and if so, what factors contribute to their lucrative salaries? Additionally, is there a noticeable trend or pattern among the most highly paid actors in Korea, such as a particular genre they tend to excel in or a specific type of role they often portray?
