Most likely, one of his relatives may have an account on Steam, and he decided to make the only Steam account in North Korea through his name. For example, I don't understand why people are not allowed to play games in North Korea, as if their lives would change if they could log into Steam and buy games... However, I rarely buy games on Steam because, in my opinion, they are too expensive there. For example, I recently decided to Buy FIFA 22 on one site that provides keys to this game much cheaper than Steam. And I was able to activate the key of this game in the Steam library, and now I'm playing FIFA 22
