[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]
'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 c'mon
Baby, be with me so happily

[Verse 2: Liam, Louis, All]
It's 4AM 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, Niall, All]
'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, 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 c'mon
Baby, be with me so happily

[Post-Chorus: Liam]
So happily

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

[Chorus: 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
I just want it to be you and I forever (Yeah, yeah)
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 who'll 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
