Lyrics:

[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 you had to walk away.

[Niall]
Cause we're on fire.
We are on fire.
We're on fire now.

[Zayn]
Yeah, we're on fire.
We are on fire.
We're on fire now.

I don't care what people say when we're together.
You know I wanna be the one to hold you when you sleep.
I just want it to be you and I forever.
I know you wanna leave.
So c'mon baby be with me
So happily.

[Liam]
It's four A.M. and I know that you're with him.
I wonder if he knows that I touched your skin.

[Louis]
And if he feels my traces in your hair
Sorry, love, but I don't really care.

[Niall]
Cause we're on fire.
We are on fire.
We're on fire now.

[Zayn]
Yeah, we're on fire.
We are on fire.
We're on fire now.

(One, two, three)

I don't care what people say when we're together.
You know I wanna be the one to hold you when you sleep.
I just want it to be you and I forever.
I know you wanna leave.
So c'mon baby be with me
So happily.

So happily.
One, two, three, four!

Oh, oh, oh, oh, oh, oh, oh, oh.
We're on fire now.
Oh, oh, oh, oh, oh, oh, oh, oh.
We're on fire now (we're on fire)
Oh, oh, oh, oh, oh, oh, oh, oh.
We're on fire now.

I don't care what people say when we're together.
You know I wanna be the one to hold you when you sleep.
I just want it to be you and I forever.
I know you wanna leave.
So c'mon baby be with me
So happily.

I don't care what people say when we're together.
You know I wanna be the one to hold you when you sleep.
I just want it to be you and I forever.
I know you wanna leave.
So c'mon baby be with me
So happily.
