[Verse 1 - Alfredo]
I know I spend a lot of time with the boys
But, girl, you know I need to have you near
Deep inside of me, I feel you fill the void
You are my atmosphere

[Chorus - Trevor, Alfredo]
You make it hard
So hard to breathe without you
Even when I‘m not thinking about you
You make it hard
So hard to breathe without you
You gave me life on the first day I found you

[Verse 2 - Trevor, Gavin]
When I‘m not with you I feel so lightheaded
I need you with me from dawn to dusk
(And all in between...)
Every time you leave me, baby, I dread it
You're my oxygen, no need to discuss
Because-

[Chorus - Trevor, Alfredo]
You make it hard
So hard to breathe without you
Even when I‘m not thinking about you
You make it hard
So hard to breathe without you
You gave me life on the first day I found you
[Spoken - Alfredo, Trevor, Gavin]
Girl, you’re the air that I breathe
I cannot survive without you
You oxygenate my red blood cells
And provide me with a fully functioning body
According to Wikipedia, the transfer of oxygen into blood is called, "diffusion"
(Aw, yeah) (Aw, yeah)
Then you return into my heart, via my bloodstream
Oh, so good
Right into my aorta
Then you slide into my capillary
Fill my cells with your love

[Chorus - Trevor, Alfredo]
You make it hard
So hard to breathe without you
Don't know how you work, but Google makes it sound true
You make it hard
So hard to breathe without you
In eighth grade, my science project was about you
