In what situation you can use ~구만 and ~구나?
안녕하세요!
친구들, Can you please explain in what situation you can use expression ~구만 and ~구나?
What makes them different? I think I get the feel when I can use ~구나, but still cannot differentiate it from ~구만.
If you can give some examples, that would be really helpful.
고마워요! ^^
