Hangul
정말 넌 다 잊었더라
반갑게 날 보는 너의 얼굴 보니
그제야 어렴풋이 아파오더라
새 살 차오르지 못한 상처가
눈물은 흐르질 않더라
이별이라 하는 게 대단치도 못해서
이렇게 보잘것없어서
좋은 이별이란 거, 결국 세상엔 없는 일이란 걸
알았다면 그때 차라리 다 울어둘걸
그때 이미 나라는 건 네겐 끝이었다는 건
나만 몰랐었던 이야기
사랑은 아니었더라
내 곁에 머물던 시간이었을 뿐
이제야 어렴풋이 알 것만 같아
왜 넌 미안했어야만 했는지
내가 너무 들떴었나 봐
떠나는 순간마저 기대를 했었다니
얼마나 우스웠던 거니
좋은 이별이란 거, 결국 세상엔 없는 일이란 걸
알았다면 그때 차라리 다 울어둘걸
그때 이미 나라는 건 네겐 끝이었다는 건
나만 몰랐었던 이야기

ENGLISH
I forgot you were
Why do not I see your face looking at me
Then came faintly ah paoh
Chao did not burn wound is a new year
The tears can not seem to
Separation is not an inch did great
This poor because
I know these are a good separation, a thing that happens in this world that ultimately
If you knew then I'd rather it
Countries had already ended, then the thing for your own thing
I did not know about me
I did not mean to
Hours have been stayed by my side as well
Now I know vaguely what I think
Why I'm sorry you've had
I look so 
Expect to hear even had time to leave
How are you going wooseuwotdeon
I know these are a good separation, a thing that happens in this world that ultimately
If you knew then I'd rather it uleodulgeol
Countries had already ended, then the thing for your own thing
I did not know about me
