I wonder whether he visited other European countries while in Switzerland. Wouldn't be surprised about France, Germany, Italy, Austria or Liechtenstein. Not a long way from Switzerland.
He went to university in Switzerland, which is why he can probably speak English and maybe even some German and/or French, but chooses to only speak Korean.
Having that be an answer is sort of out of character for JetPunk quizzes: Germany doesn't count as a German-speaking country; Countries in NATO aren't close to NATO countries, etc.

How the hell he has been to it from the moment he is there already...?
He was born in 83/84; his grandfather was ruling back then so the prompt is a bit weird.
