What's the 'feel' of 그대, meaning 'you'?

Question

I've read that 그대 is a 'poetic' way of meaning 'you' - i.e. referring to the person you're speaking to. I saw an example sentence: > 앉으나 서나 그대 생각을 해요 Where it seems to be 'loving' in tone. However, on the one or two occasions I actually heard it, it was used by a boss talking to a younger employee - so (probably?) not 'romantically' loving. What are the different ways that 그대 can be used?

Answer 1

It is one of sarcastic form of "you" this time.

Some Koreans they use 그대 as sarcastic way or joke style.
