[Intro: Chaeyoung]
He-he-he
One spark, baby

[Verse 1: Nayeon, Jihyo]
Everybody wants that endless flame
Heatin' up like an everlasting blast
Eternally hopin' we can stay where we'll keep sparkling beautifully
Forever's here if you just stick with me

[Pre-Chorus: Mina, Momo, Jihyo]
Young and wild and free, breathe it into me
Keep me warm with all your energy
If I lose my rhythm
Then your beat goes on and on (And on and on)
Bring me the, bring me the spark in my veins
Gimme the freedom, the freedom to chase
You know it's all ours
So don't you stop, make this moment last

[Chorus: Nayeon, Sana, Jeongyeon, Dahyun]
'Cause my heart is burnin', burnin', burnin'
So good that it's hurting, hurting, hurting
How do you make the pain so perfect
My favorite person, it's our golden days
Yeah, my heart is burning, burning, burning
Don't lose this spark, baby
[Post-Chorus: Nayeon, Jihyo, Chaeyoung]
My heart's burnin', up, oh, oh (One spark, baby)
My heart's burnin', up, oh, oh
My heart's burnin', up, oh, oh (One spark, baby)
My heart's burnin', up, oh, oh

[Verse 2: Momo, Jeongyeon]
Layin' in the glow, coral light heaven
Make me blush so much, my cheeks all red
'Cause you're as natural as water
Couldn't get any hotter

[Pre-Chorus: Tzuyu, Jihyo, Nayeon, Dahyun]
Young and wild and free, breathe it into me
Keep me warm with all your energy
If I lose my rhythm
Then your beat goes on and on (And on and on)
Bring me the, bring me the spark in my veins
Gimme the freedom the freedom to chase
You know it's all ours
So don't you stop make this moment last (Baby)

[Chorus: Jeongyeon, Dahyun, Sana, Momo]
'Cause my heart is burning, burning, burning
So good that it's hurting, hurting, hurting
How do you make the pain so perfect
My favorite person, it's our golden days
Yeah, my heart is burning, burning, burning
Don't lose this spark, baby
[Post-Chorus: Nayeon, Jihyo, Chaeyoung]
My heart's burnin', up, oh, oh (One spark, baby)
My heart's burnin', up, oh, oh
My heart's burnin', up, oh, oh (One spark, baby)
My heart's burnin', up, oh, oh

[Bridge: Mina, Sana, Tzuyu, Chaeyoung, *Nayeon*]
Lighting it up, we got the shine that breaks the darkness
The shine that breaks the darkness
Glowing so bright
Our fantasies become a promise
This is the time of our lives, carved into our minds
Flying high, baby, there ain't no sundown
An everlasting spark to an everlasting fire
Don't let this fire die (*Oh, I'm burnin' on, ooh*)

[Chorus: Jihyo, Tzuyu, Chaeyoung, Dahyun, *Nayeon*]
'Cause my heart is burning, burning, burning (*My heart's burnin', yeah*)
So good that it's hurting, hurting, hurting (*Hurting, ooh*)
How do you make the pain so perfect
My favorite person, it's our golden days (*Yeah, woah*)
Yeah, my heart is burning, burning, so burning (Oh-oh, oh-ooh)

[Post-Chorus: Chaeyoung]
One spark, baby
One spark, baby
One spark, baby
One spark, baby
