Hangul Lyrics
You’ll always be my blue valentine
You’ll always be my blue valentine
식어버린 너의 색은 blue
파랗게 멍이 든 my heart
몇 번이고 덧이 나
열이 나 lovesick
이건 such a bad love
We fight, we sigh, and stop
붉게 타오르다 한순간에 식어가
Rewind, rewind, rewind
언제 그랬냐는 듯이 또 서롤 찾아
깊게 새긴 상처
비친 red blood
부서진 forever
I can see it now
Can you see it now?
우린 마치 broken glass on the ground
돌이킬 수 없다 해도
We can figure it out
If this love is over
다시 뛰어들어 난
이 사랑은 colder
I’ll keep the fire lit in mine
You’ll always be my blue valentine
You’ll always be my blue valentine
식어도 타오르는 얼음 속 불꽃
아무 겁도 없이 뻗어버린 손
Hot and icy
But I like it
It’s so you
바뀌어 맘의 weather
몰려온 cloud
외로운 together
I can feel it now
Can you feel it now?
Rollercoaster처럼
우린 정신없이
흔들려도
돌아갈 걸 알아
So it doesn’t matter
You might be my end game
대가로 얻은 worst pain
(You might be)
If this love is over
다시 뛰어들어 난
이 사랑은 colder
I’ll keep the fire lit in mine
You’ll always be my blue valentine
You’ll always be my blue valentine
붉고 푸른
사랑이란 bruise
낫지는 않길
Cause it’s you (yeah)
If this love is over
다시 뛰어들어 난 (뛰어들어 난)
이 사랑은 colder (colder, yeah)
I’ll keep the fire lit in mine
You’ll always be my blue valentine
(Always be, my blue valentine)
You’ll always be my blue valentine
I’m falling over and over and over, ah
You’re getting colder and colder and colder
Blue valentine

Blue valentine
English Translation
You’ll always be my blue valentine
You’ll always be my blue valentine
The color of you that’s faded is blue
My heart bruised blue
Again and again, the wound opens
It burns — lovesick
This is such a bad love
We fight, we sigh, and stop
Burning red, then cooling down in an instant
Rewind, rewind, rewind
As if nothing happened, we find each other again
Deeply carved scars
Reflected red blood
Broken forever
I can see it now
Can you see it now?
We’re like broken glass on the ground
Even if we can’t turn back
We can figure it out
If this love is over
I’ll dive back in again
This love is colder
I’ll keep the fire lit in mine
You’ll always be my blue valentine
You’ll always be my blue valentine
A flame that burns even in frozen ice
A hand reaching out without fear
Hot and icy
But I like it
It’s so you
Changing weather of my heart
Clouds gather
Lonely together
I can feel it now
Can you feel it now?
Like a rollercoaster
We shake endlessly
Even if we tremble
I know we’ll come back again
So it doesn’t matter
You might be my end game
The worst pain I earned as the price
(You might be)
If this love is over
I’ll dive back in again
This love is colder
I’ll keep the fire lit in mine
You’ll always be my blue valentine
You’ll always be my blue valentine
Red and blue
A bruise called love
I hope it never heals
Cause it’s you (yeah)
If this love is over
I’ll dive back in again (dive back in)
This love is colder (colder, yeah)
I’ll keep the fire lit in mine
You’ll always be my blue valentine
(Always be, my blue valentine)
You’ll always be my blue valentine
I’m falling over and over and over, ah
You’re getting colder and colder and colder
Blue valentine
