Eunah

This is generally a Korean female name. Eunah is not an old name but not a very common name as well. It sounds lovely and simple. And speak from my experience, many foreigners (except Korean) can't pronounce it correctly. Because the pronounciation of "Eun" doesn't exist in English. So as a person having name Eunah, I just let people call me "Yuna" (bc it is really annoying to hear people always misread my name. Some people even called me Anna or Yunnna...)
