Who is the richest man in Korea?

Could you tell me who currently holds the title of being the wealthiest individual in Korea? I'm quite curious about the identity of this person and the nature of their wealth, whether it stems from cryptocurrency investments, traditional business ventures, or perhaps a combination of both. Additionally, I'm also interested in knowing how they've managed to accumulate such a significant fortune in a country like Korea, which is known for its thriving economy and vibrant business scene.
