[Korean:]

그런 날 있잖아
이유 없이 슬픈 날
몸은 무겁고
나 빼곤 모두 다
바쁘고 치열해 보이는 날
발걸음이 떨어지질 않아
벌써 늦은 것 같은데 말야
온 세상이 얄밉네

Yeah 곳곳에 덜컥거리는 과속방지턱
맘은 구겨지고 말은 자꾸 없어져
도대체 왜 나 열심히 뛰었는데
오 내게 왜

집에 와
침대에 누워
생각해봐
내 잘못이었을까
어지러운 밤
문득 시곌 봐
곧 12시

뭔가 달라질까
그런 건 아닐 거야
그래도 이 하루가
끝나잖아
초침과
분침이 겹칠 때
세상은 아주 잠깐 숨을 참아
Zero O'Clock

And you gonna be happy
And you gonna be happy
막 내려앉은 저 눈처럼
숨을 쉬자 처음처럼
And you gonna be happy
And you gonna be happy
Turn this all around
모든 게 새로운
Zero O'Clock

조금씩 박자가 미끄러져
쉬운 표정이 안 지어져
익숙한 가사 자꾸 잊어
내 맘 같은 게 뭐 하나 없어
그래 다 지나간 일들이야
혼잣말해도 참 쉽지 않아
Is it my fault?
Is it my wrong?
답이 없는
나의 메아리만

집에 와
침대에 누워
생각해봐
내 잘못이었을까
어지러운 밤
문득 시곌 봐
곧 12시

뭔가 달라질까
그런 건 아닐 거야
그래도 이 하루가
끝나잖아
초침과
분침이 겹칠 때
세상은 아주 잠깐 숨을 참아
Zero O'Clock

And you gonna be happy
And you gonna be happy
막 내려앉은 저 눈처럼
숨을 쉬자 처음처럼
And you gonna be happy
And you gonna be happy
Turn this all around
모든 게 새로운
Zero O'Clock

두 손 모아
기도하네
내일은 좀
더 웃기를
For me
좀 낫기를
For me

이 노래가
끝이 나면
새 노래가
시작되리
좀 더 행복하기를 yeah

And you gonna be happy
And you gonna be happy
아주 잠깐 숨을 참고
오늘도 나를 토닥여
And you gonna be happy
And you gonna be happy
Turn this all around
모든 게 새로운
Zero O'Clock

[English translation:]

You know those days
Those days where you're sad for no reason
Those days where your body is heavy
And it looks like everyone else except you is busy and fierce
My feet won't set off, though it seems like I'm already too late
I'm hateful of the whole world

Yeah, here and there are click-clacking speed bumps
My heart grows crumpled and my words lessen
Why the hell? I ran so hard
Oh why to me

Come home and lie in bed
Thinking if it was my fault?
Dizzy night, looking at the clock
Soon it will be midnight

Will something be different?
It won't be something like that
But this day will be over
When the minute and second hands overlap
The world holds its breath for a little while
Zero O'Clock

And you gonna be happy
And you gonna be happy
Like that snow that just settled down
Let's breathe, like the first time
And you gonna be happy
And you gonna be happy
Turn this all around
When everything is new
Zero O'Clock

The beat slips away little by little
I can't put on an easy face
I keep forgetting familiar lyrics
There's nothing going my way
Yes, it's all in the past
Even talking to myself, it's not easy
Is it my fault?
Is it my wrong?
Only my echo comes back with no answer

Come home and lie in bed
Thinking if it was my fault?
Dizzy night, looking at the clock
Soon it will be midnight

Will something be different?
It won't be something like that
But this day will be over
When the minute and second hands overlap
The world holds its breath for a little while
Zero O'Clock

And you gonna be happy
And you gonna be happy
Like that snow that just settled down
Let's breathe, like the first time
And you gonna be happy
And you gonna be happy
Turn this all around
When everything is new
Zero O'Clock

Put my hands together to pray
Hoping that tomorrow I'll laugh more
For me
It'll be better
For me

When this song ends
May a new song begin
Hoping that I'll be a little happier, yeah

And you gonna be happy
And you gonna be happy
Like that snow that just settled down
Let's breathe, like the first time
And you gonna be happy
And you gonna be happy
Turn this all around
When everything is new
Zero O'Clock
