Hearts2Hearts “Blue Moon” Lyrics

Hangul

Mm-mm, oh-oh-oh

잊혀진 뭔갈 깨운 것 같아 아주 조금씩
소중히 아껴 듣고 싶던 멜로디
밀려든 사이
나란히 뜨는 rainbow, rainbow
물들어 와
너와 꿈꾸는 채로, oh, 이대로, yeah (Ooh-ooh)

한여름 밤의 꿈 we are
Tonight, tonight, tonight

In the blue moon
서롤 비춘 눈빛과
노을빛에 물든 달빛
마주 보는 우리 같지
내게 힘이 돼 준 목소리
So good with you
우리만의 blue moon (Yeah)

어두운 밤 더운 바람 내리는 빛 (Yeah)
모든 게 다 완벽한 time, yeah
달빛이 잠든 이곳엔
솔직함만이 가득해 (Woo)
가만히 눈을 감은 채, 너와 나 (Yeah; Ooh-ooh)

한여름 밤의 꿈 we are
Tonight, tonight, tonight

In the blue moon
서롤 비춘 눈빛과
노을빛에 물든 달빛
마주 보는 우리 같지
내게 힘이 돼 준 목소리 (Oh-oh, ooh-ooh)
So good with you
우리만의 blue moon

Now I’m falling
쏟아진 별빛 사이 끝없이 빠져든 dream
With you

In the blue moon
서롤 비춘 눈빛과 (Hm-mm)
노을빛에 물든 달빛 (Yeah, yah)
마주 보는 우리 같지 (Oh, yeah)
내게 힘이 돼 준 목소리 (Oh-oh, ooh-ooh)
So good with you (Yeah, yeah-eh-eh)
(With you, yeah) 우리만의 blue moon

Na-na-na-na (Hm-mm)
Tonight, tonight, tonight (Oh-oh, oh, ooh)
Mm-mm, mm, no
Tonight, tonight, tonight (Mm, ooh)

Translation

Mm-mm, oh-oh-oh

It feels like something forgotten has been awakened, very slowly, bit by bit
A melody that I wanted to cherish and listen to so carefully
In the moment it came rushing in,
A rainbow, rainbow rises side-by-side
Washing over and coloring us in
While dreaming together with you, oh, just like this, yeah (Ooh-ooh)

A midsummer night’s dream, we are
Tonight, tonight, tonight

In the blue moon
Our gazes shining upon one another,
And the moonlight dyed in the colors of the sunset
It’s just like us, looking face-to-face at each other
The voice that always gave me strength
So good with you
A blue moon that belongs only to us (Yeah)

The dark night, the warm breeze, the falling light (Yeah)
Every single thing is a perfectly flawless time, yeah
In this place where the moonlight has fallen asleep,
It is filled with nothing but absolute honesty (Woo)
While quietly keeping our eyes closed, you and I (Yeah; Ooh-ooh)

A midsummer night’s dream, we are
Tonight, tonight, tonight

In the blue moon
Our gazes shining upon one another,
And the moonlight dyed in the colors of the sunset
It’s just like us, looking face-to-face at each other
The voice that always gave me strength (Oh-oh, ooh-ooh)
So good with you
A blue moon that belongs only to us

Now I’m falling
An endless dream that I’m falling deep into, amidst the pouring starlight
With you

In the blue moon
Our gazes shining upon one another (Hm-mm)
And the moonlight dyed in the colors of the sunset (Yeah, yah)
It’s just like us, looking face-to-face at each other (Oh, yeah)
The voice that always gave me strength (Oh-oh, ooh-ooh)
So good with you (Yeah, yeah-eh-eh)
(With you, yeah) A blue moon that belongs only to us

Na-na-na-na (Hm-mm)
Tonight, tonight, tonight (Oh-oh, oh, ooh)
Mm-mm, mm, no
Tonight, tonight, tonight (Mm, ooh)
