[Verse 1: Haechan]
Tell me about your dreaming
I believe I was there too
I could sense your breathing
Lying in a different room.

[Verse 2: Jeno, Jaemin, Renjun, Haechan]
Cause lights of the universe (Yeah, yeah)
Always there to observe
You shimmer
Your inner compass is taking you there (Take you down)
I'll be your beacon illuminate while you on your way
Girl I've been there too(Been there too)

[Pre-Chorus: Renjun, Jisung, Chenle, Haechan]
Don't be afraid tonight, afraid tonight (Oh, yeah)
Just know you'll never be lonely
I know it’s hard sometimes to see the light (See the lights)
But you and I keep on dreaming
(Come on!)

[Chorus: All, Haechan]
We gon' light it up
Light it up now darling
We can make the stars align
We gon' light it up
Light it up, now we sparkling
Brighter than the fireflies (Fireflies)

[Verse 3: Renjun, Jaemin]
Think it then believe it
And truth will find its way
I know that you will see it (Mmm, mmm, mmm)
If you come with me
(Alright, alright, hey)

[Verse 4: Jaemin, Jeno, Jisung]
Show you what it's all about
Now we're gonna go all out
Don't gotta sing the blues (Oh, yeah, yeah, yeah)
If you ever need me shout
I will always be around (Oh, oh)
Girl I've been there too (Oh, yeah)

[Pre-Chorus: Chenle, Haechan, Jeno]
Don't be afraid tonight, afraid tonight
Just know you'll never be lonely (Never be lonely)
I know it's hard sometimes to see the light
But you and I keep on dreaming.

[Chorus: All, Haechan]
We gon' light it up
Light it up now darling (Oh, oh, yeah)
We can make the stars align
We gon' light it up
Light it up, now we sparkling
Brighter than the fireflies.

[Post-Chorus: All, Jeno, Jaemin, Jisung, (Haechan)]
Oh, oh, oh
We gonna light it up
Oh, oh, oh, hey!
Look how we shining now (Shining now)
Oh, oh, oh
You know it's only love
(Brighter than the fireflies)

[Bridge: Chenle, Renjun, Haechan, (All)]
Light it up (Hey, hey)
Light it up (Hey, hey)
Like it's the first day of our lives (Hey, hey)
Fireflies, fireflies (Fireflies) (Hey, hey)
They see us dancing in the sky
We gon', we gon'.

[Chorus: All, Haechan]
We gon' light it up
Light it up now darling
We can make the stars align
We gon' light it up
Light it up now we sparkling
Brighter than the fireflies

Oh, oh, oh

Oh, oh, oh
Look how we shining now
Oh, oh, oh
You know it's only love
