Can I retire in South Korea from UK?

Could you please advise me on the possibility of retiring in South Korea while residing in the UK? I am interested in relocating to South Korea in my retirement, but I am uncertain about the legal and financial implications of doing so. Could you provide me with information on any relevant visa requirements, tax regulations, and any other factors I should consider? Additionally, I would appreciate any advice on finding suitable accommodation, accessing medical care, and integrating into the local community. Thank you for your assistance.
