Hi all, I was reading the lyrics of a song called "Happy Things," and had a question about the 4th line of the following verse: 예상대로 일이 술술 풀려갈 때 이제부터 뭐든 내 멋대로 맘 먹을 때 아주 맛있는걸 먹었을 때 세상에나~! 힘도 안 줬는데 쾌변 Does 세상에나~! mean "even in the whole entire world"??? And does 힘도 안 줬는데 쾌변 mean "to be eloquent even without trying"?? Any help is appreciated, thanks!
