[Korean:]

I believe in love, I believe in love
I believe in you

사랑이라는 말은 조금 일러
배운 적 없는 something
너의 이름도 아직 낯설지만
자꾸만 들뜬 이상한 맘
꽤 오랜 밤, 날 부르던 네 목소리
Ew, 늘 고장 난 것처럼 지지직대
생각보다 더 먼 곳에 있는 걸까?
왜 선명하질 않니

꿈에 그려본 그 모습
멀리 있어도 I don't care
우리 만날 그날까지 난 계속 trying
Oh, baby

얼마나 기다려야 하는 거니 my guy (Guy)
갈수록 물음표는 쌓여만 가니 (Ha-ha)
If you wanna be my guy (Guy)
한 번만 더 신호를 보내와 주길

Du-bi-ri, my, my, my guy
Du-bi-ri, my, my, my guy
Du-ru-bi, my, my, my guy
Du-ru-bi-ri, my, my, my guy

너의 커다란 키처럼 커진 맘
여전히 can't forget you
하고 싶은 말 자꾸 쌓이는데
마지막 같은 인사는 why?

꿈에 그리던 그 모습
희미해져 가 I'm afraid
다시 만날 그날까지 난 계속 trying
Oh! Baby

얼마나 기다려야 하는 거니 my guy (Guy)
갈수록 물음표는 쌓여만 가니 (Ha-ha)
If you wanna be my guy (Guy)
한 번만 더 신호를 보내와 주길

Du-bi-ri, my, my, my guy
Du-bi-ri, my, my, my guy
Du-ru-bi, my, my, my guy
Du-ru-bi-ri, my, my, my guy

I believe in love, I believe in love
I believe in you-ooh-ooh-ooh
I believe in love, I believe in love
Why you're gone? Baby
