Korean:

Oh
Yeah, yeah

Can’t believe, 눈앞의 넌
모든 게 그대론데
난 모르는 미소를 짓고 있어
심연 같은 눈동자
그 너머 너를 찾아봐도
낯설어, who are you?
내가 사랑하는 넌 누군지

혼란 속의 몰락
어지러워 baby
난 널 아는 걸까
뭔가 변한 걸까
제발 대답해 봐
내가 틀린 걸까?

Fatal trouble
It’s getting blurry
너의 기억이
무너져내려
Fatal trouble
널 향한 마음도
오랜 믿음도
다 coming undone

I don’t know you (I don’t know you)
난 무너져가 (난 무너져가)
헤메고 있어 (헤매고 있어)
널 지키게 해줘
Fatal trouble
같은 memory
또 다른 story
날 흔들어놔
Fatal trouble

Ah, 겨우 지켜낸
널 잃긴 싫은데
불안이 드리워
점점 여윈 달 같이
흐려져 확신이
I don’t know what to do

혼란 따윈 don’t mind
집중하는 감각
분명 너는 하나
So now, 뒤로 해 다
내 심장이 뛰는
대로 걸어가 난

Fatal trouble
It’s getting blurry
너의 기억이
무너져내려
Fatal trouble
널 향한 마음도
오랜 믿음도
다 coming undone

I know, I know you (I know, I know you)
자 말해 내게 (말해 내게)
아니라고 (아니라고)
변한 건 없다고
Fatal trouble
하나의 영혼
믿어 내 답을
틀리지 않아
Fatal trouble

English:

Oh
Yeah, yeah

Can’t believe, the you before my eyes
Everything is the same
But you’re smiling a smile I don’t know
Eyes like an abyss
Even when I try to find you beyond them
It’s unfamiliar, who are you?
Who is the you I love?

Collapse in confusion
I’m dizzy baby
Do I know you?
Has something changed?
Please answer me
Am I wrong?

Fatal trouble
It’s getting blurry
Your memories
Are collapsing
Fatal trouble
My feelings for you
Even my long-held beliefs
Are all coming undone

I don’t know you (I don’t know you)
I’m collapsing (I’m collapsing)
I’m wandering (I’m wandering)
Let me protect you
Fatal trouble
The same memory
But a different story
Shakes me
Fatal trouble

Ah, I barely held on
I don’t want to lose you
Anxiety looms
Like a thinning moon
Certainty grows faint
I don’t know what to do

Don’t mind confusion
Focus on the senses
You are certainly one
So now, put it all behind
I walk as my heart
Beats

Fatal trouble
It’s getting blurry
Your memories
Are collapsing
Fatal trouble
My feelings for you
Even my long-held beliefs
Are all coming undone

I know, I know you (I know, I know you)
Now tell me (tell me)
Say it’s not (say it’s not)
That nothing has changed
Fatal trouble
One soul
Trust my answer
I’m not wrong
Fatal trouble
