[Verse 1: Harry]
You don't understand, you don't understand
What you do to me when you hold his hand
We were meant to be, but a twist of fate
Made it, so we had to walk away

[Pre-Chorus: Zayn, Harry]
'Cause we're on fire, we are on fire
We're on fire now
Yeah, we're on fire, we are on fire
We're on fire now (One, two three!)

[Chorus: Harry, Louis, All]
I don't care what people say when we're together
You know I wanna be the one
Who'll hold you when you sleep (Hey!)
I just want it to be you and I forever
I know you wanna leave, so come on
Baby, be with me so happily

[Verse 2: Liam, All, Louis]
It's 4 A.M. and I know that you're with him (Yeah)
I wonder if he knows that I touched your skin
And if he feels my traces in your hair (Yeah)
I'm sorry, love, but I don't really care
[Pre-Chorus: Liam, All, Niall, Harry]
'Cause we're on fire, we are on fire
We're on fire now (Yeah)
Yeah we're on fire, we are on fire
We're on fire now (One, two, three!)

[Chorus: Niall, Liam, All, Louis]
I don't care what people say when we're together
You know I wanna be the one
Who holds you when you sleep (Hey!)
I just want it to be you and I forever
I know you wanna leave, so come on
Baby, be with me so happily

[Bridge: Liam, Harry, Zayn]
So happily
One, two, three, four!
Oh oh oh, oh oh, oh oh oh oh
We're on fire now (So happily)
Oh oh oh, oh oh, oh oh oh oh (Oh oh oh)
We're on fire now (We're on fire now; We're on fire)
Oh oh oh, oh oh, oh oh oh oh
We're on fire now
I don't care, yeah

[Chorus: All, All, Niall, Harry]
I don't care what people say when we're together
You know I wanna be the one
Who'll hold you when you sleep (Hey!)
I just want it to be you and I forever (Yeah, yeah)
I know you wanna leave, so come on
Baby be with me so happily
I don't care what people say when we're together
You know I wanna be the one
Who'll hold you when you sleep (Hey!)
I just want it to be you and I forever
I know you wanna leave, so come on
Baby, be with me so happily
