Is there any slightly difference between 그레요? 진짜? and 정말?
So 정말 is more like truly? Are you serious? and 진짜? is more like oh really? and I get it because it's not a big difference in english but it is in my language, but I don't really see the difference between 그레요? and 진짜? Is there any? You can give me some examples.
