[Korean:]

널 잊어보려 계속 노력하고 있어
괜히 더 즐거운 척
시간을 보내는 날 넌 모르겠지

행복한 척하며 지내다 보면 언젠가
너를 잊게 될 거라 믿으며
살고 있는 날 모르겠지

내가 노력해봐도 너 때문이라서
너는 더 짙어져 가고

혼자 남겨진 시간을 보내는 게 이젠
내겐 너무 두려운 일이
돼버렸단 걸 넌 모르겠지

네 꿈을 꾸는 밤이 오는 게 난 두려워
이젠 내게 밤이
무서워졌다는 걸 너는 모르겠지

내가 노력해봐도
너 때문이라서 너는 더
짙어져 가고
너를 그리고
노력할수록
너는 계속 커져만 가겠지

짙어져 가는
너를 붙잡고
생각할수록
너는 계속 커져만 가겠지

널 잊어보려 항상 노력하고 있어
괜히 더 즐거운 척
살아보고 있는 날 넌 모르겠지

[English translation:]

I keep trying to forget you
Acting like I'm having fun
But you probably don't know

If I act like I'm happy
I believe I'll forget you some day
You probably don't know that's what I think

I try but because it's you
You grow even thicker in me

Spending this time alone
Is so scary to me
But you probably don't know

I'm afraid of nights that I'll dream of you
Nights are scary to me know
You probably don't know

I try but because it's you
You grow even thicker in me
The more I try, the bigger you grow

Holding onto you, who grows thicker
The more I think of you
The bigger you grow

I'm always trying to forget you
Acting like I'm having fun
But you probably don't know
