[Verse 1: Letty]
All was dark, it showed up, first light
First chapter begins with the light of sight
All the spark comin' down with no plans
The history 'bout to begin
Baby you and I are revolving
Around the darkness we're evolving
Between the time and space we're looking
Something that has never been explored

[Pre-Chorus: Letty & RAP]
You and I, we're flying through the darkness
Even we don't know we're fighting for each other
I'm here baby, please keep moving forward
Spread your wings and hit my heart
WAIT!? THAT'S A BIG BANG!!!

[Chorus: Letty & RAP]
You and I, we're flying through the darkness
Even we don't know we're fighting for each other
I'm here baby, please keep moving forward
Spread your wings and hit my heart
That's a Big Bang

[Verse 2: RAP]
(yo! yo! my turn!)
Baby girl you're the satelitte of my World (Woo~)
The Universe that can never be describe with words (Ssshh~)
You are Proton (What!?)
I'm a Neutron (Who??)
And the Almighty holdin' that Electron
People say "I love you to the moon and back" (I love you)
But I'm just a man who will always got your back (Hello!)
Baby don't leave (Don't!)
Baby stay stick (Please!)
I'm a bit weird (What!?)
Baby please don't disappear (Yeah!)
[Pre-Chorus: Letty & RAP]
You and I, we're flying through the darkness (We're flying)
Even we don't know we're (We don't even know)
fighting for each other (Yeah)
I'm here baby, please keep moving forward (I'll find you)
Spread your wings and hit my heart (SPREAD YOUR WINGS)
(AND HIT MY HEART MAKE A BIG BANG!)

[Chorus: Letty & RAP]
You and I, we're flying through the darkness
Even we don't know we're fighting for each other
I'm here baby, please keep moving forward
Spread your wings and hit my heart
That's a Big Bang
