[Korean:]

듣지 말았어야 할 얘기
오늘 하루쯤은
잊고 나와도 좋았을 전화
말문이 막히는 얘기
어차피 내 마음은
상관 없는 얘기

어떻게 너를 잊을까
잊으려고 애를 써볼까
다시 돌아갈 순 없을까
아무 말도 꺼낼 수가 없었던
우리 마지막 얘기

사랑한다 말을 했을 땐
넌 멈춰버렸고
난 가슴은 터질 듯 했는데
지금 난 멈춰버리고
네 다음 얘기를 기다릴 뿐야

어떻게 너를 잊을까
잊으려고 애를 써볼까
다시 돌아갈 순 없을까
어떻게도 아프기만 한 얘기
그만하자는 그 얘기

멈출 수만 있다면
지울 수만 있다면
다시 돌아간다면
처음 만난 그 날로

어떻게 너를 잊을까
잊으려고 애를 써볼까
다시 돌아갈 순 없을까
입을 막은 채로 눈물 흘리는
믿기 싫은 이야기

어떻게 너를 잊을까
잊으려고 애를 써볼까
다시 돌아갈 순 없을까
여전히 널 사랑하기 때문에
꿈에서라도
믿기 싫은 이야기

[English translation:]

Words I shouldn't have listened to
Just for one day
If only I had forgotten my phone
Words that cause me to be at a loss for words
Words that don't care
About my feelings anyway

How could I forget you
Should I try to forget you
Couldn't we go back to what it used to be
I was unable to say a single thing
During our last words to each other

When I told you that I loved you
You stopped and
My heart felt as if it would explode
But now, I'm the one who has stopped
As I do nothing but wait for your next words

How could I forget you
Should I try to forget you
Couldn't we go back to what it used to be
Words that are painful, no matter how you look at them
Words saying we should end it all

If only I could stop it
If only I could erase it
If only I could go back
To the day we first met

How could I forget you
Should I try to forget you
Couldn't we go back to what it used to be
I cover my mouth as tears stream down my face
To the words that are hard to believe

How could I forget you
Should I try to forget you
Couldn't we go back to what it used to be
Because I still love you
Even in my dreams
They are words that are hard to believe
