[Verse 1: Harry]

You don't understand, you don't understand (Yeah)

What you do to me when you hold his hand (Hey)

We were meant to be, but a twist of fate (Yeah)

Made it so we had to walk away (Hey)

[Pre-Chorus: Niall, 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: All, 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

I know you wanna leave, so c'mon

Baby, be with me so happily

[Verse 2: Liam, Louis, All]

(Hey) It's 4AM and I know that you're with him

(Yeah) I wonder if he knows that I touched your skin

(Hey) And if he feels my traces in your hair

(Yeah) I'm sorry, love, but I don't really care

[Pre-Chorus: Niall, 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: All, Harry, Liam]

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

So happily

[Bridge: Harry, All, Liam]

One, two, three, four

Oh-oh-oh, oh-oh, oh-oh-oh-oh, we're on fire now

Oh-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-oh, we're on fire now

[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
