NMIXX “Blue Valentine” Lyrics
Hangul
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
Romanized
You’ll always be my blue valentine
You’ll always be my blue valentine

You’re getting colder and colder and colder
Blue valentine
Translation
You’ll always be my blue valentine
You’ll always be my blue valentine
Your color’s faded now to blue
Gone bruised blue, my heart
It keeps getting worse over and over
Fever high, lovesick
This is such a bad love
We fight, we sigh, and stop
Burning in red then freeze all at once
Rewind, rewind, rewind
As if nothing happened, we find each other again
A scar left deeply
Reflection of red blood
A 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 undo it
We can figure it out
If this love is over
I’d still 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 in the ice survives even if it becomes cold
Fearlessly stretched my hand
Hot and icy
But I like it
It’s so you
Changing, the heart’s weather
Roll in cloud
Lonely in together
I can feel it now
Can you feel it now?
Rollercoaster
even though we’re
shaken and unstable
Truth is we’ll come back together
So it doesn’t matter
You might be my end game
The cost is this worst pain
(You might be)
If this love is over
I’d still 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 red and blue
bruise called love
I don’t want it to heal
Cause it’s you (yeah)
If this love is over
I’d still dive back in again (I’d still 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
NMIXX “Blue Valentine” Meaning
Just before arriving in Mixtopia, NMIXX enters the Blue Valentine Stage, where the six girls discover that this adventure is actually their Nth one — and that they have failed every single time at this stage in the past. Within MMU, opinions are divided on whether they should risk everything to complete the journey or turn back. As emotions intensify, each member’s impetus — the energy that fuels MMU — begins to clash and scatter in all directions until the engine ultimately explodes. The girls then come face-to-face with the ambivalence of love, confronting the inevitable conflicts that arise between people who care for one another. Because they love, they hurt; and because they love, they get hurt. This cycle repeats endlessly, expressing a longing to rekindle warmth in hearts that have grown cold at the point where emotions collide.


Within days of its release, the song cracked the Top 20, then the Top 10, before ultimately soaring to #1 on both Bugs and Melon on October 20, marking NMIXX’s first-ever digital chart-topper. The track’s success not only gave the group a long-awaited breakthrough but also ended the record-breaking 100-day reign (2,388 hours) of Golden by virtual group HUNTR/X, the longest-running K-pop chart-topper in history. Once dismissed as JYP’s “forgotten daughters,” the six members of NMIXX have now rewritten their story — proving that perseverance, artistry, and perfect timing can transform even the most unlikely journey into a defining moment in K-pop history.
