유난히 어둠을 무서워하던 아이
잠에 들기 전 그 순간이 왜 그리
겁이 났는지 전화기 너머로 들린
포근한 목소리에 마음 놓았던

우리만의 some story 함께 나눈 비밀
어느새 바랜 기억을 안고
One step two step

Uh 내 키만큼 자라난 그림자
날 꼭 닮은 익숙한 니 모습에 I know
그래 우린 늘 함께 걸어왔는걸 oh you are
변하지 않는 my best friend
언제나처럼 그 자리에

조금 다투면 어때 금세 풀어질 텐데
또 아무렇지 않게 실없는 농담을 던지며
웃기지 시간은 계속 흐르는데
어쩜 그대로잖아 변한 게 없어

우리만의 some story 셀 수 없는 매일
차곡히 쌓인 기억을 안고
One step two step

Uh 내 키만큼 자라난 그림자
날 꼭 닮은 익숙한 니 모습에 I know
그래 우린 늘 함께 걸어왔는걸 oh you are (you are)
변하지 않는 my best friend

아무 준비 없이 나선 이 길의
끝을 몰라도 괜찮아

내 키만큼 자라난 그림자 (자라난 그림자 yeah)
날 꼭 닮은 익숙한 니 모습에 I know
그래 우린 늘 함께 걸어왔는걸 oh you are (you are)
변하지 않는 my best friend

변하지 않는 my oh
One step two step
언제나처럼 그 자리에
One step two step

One step two step
One step two step

A kid who was especially scared of the dark
Why was I so scared right before I went to sleep?
But when I heard your voice over the phone
I felt at ease

It's our some story, a secret we shared
Suddenly those memories faded
One step two step

My shadow grew as much as my height
You've resembled me, I know
We always walked together, oh you are
My never-changing, my best friend
Always in that same place

Who cares if we fight, we'll make up soon anyway
Throwing jokes at each other as if nothing's wrong
It's funny, time keeps passing
But how come things don't change?

It's our some story
Memories that built up countlessly
One step two step

My shadow grew as much as my height
You've resembled me, I know
We always walked together, oh you are
My never-changing, my best friend

On this path that we stood on without preparation
We don't know the end but it's alright

My shadow grew as much as my height
You've resembled me, I know
We always walked together, oh you are
My never-changing, my best friend

My never-changing, my oh
One step two step
Always in that same place
One step two step
