How to say "Fine!!" In Korean
I have been watching a few dramas. And a character will often say a quick word that is subtitled "Fine" or "OK." But it's not like an answer to a question about how you are feeling. Sometimes it seems like an exasperated sort of "Have it your way" or "Just go do it." I don't even know if I can romanize it from what I hear... Maybe "kray" (which isn't obviously an official romanization). Ideas anyone?

Answer

It must be "그래".
그래 is a short form of 
그렇게 해 "Have it your way" or "Just go do it."
그러해 "Yes", "OK", "Really?"
