Korean was a language that naturally developed on the Korean peninsula. King Saejong the Great was responsible for devising the current Hangeul alphabet for the Korean language. (It previously used the Chinese ideographs -- Hanzi.) Korean is not a created language; it is not Esperanto or Klingon.

"Only for you" is written as "dangsin man-ui" in the Korean language.

You could study Korean language because you need to know the language for business or other matters, as a second language, or because you want to know the language of your ancestors, if you are of Korean heritage.
