Can Brits move to South Korea?

Excuse me, I have a question. I'm a British citizen and I'm considering relocating to South Korea. Is it possible for me to move there and live there permanently? I'm interested in the culture, the food, and the opportunities that South Korea has to offer. Do I need a special visa or permit? And what are the general requirements or steps that I need to follow in order to make this happen? I'd appreciate any information or advice you can provide.
