[Verse 1: Zayn]
Been sitting eyes wide open
behind these four walls, hoping you'd call
It's just a cruel existence
like there's no point hoping at all

[Pre-Chorus 1: Zayn]
Baby, baby, I feel crazy, up all night
all night and every day
Give me something, oh, but you say nothing
What is happening to me?

[Chorus: Zayn]
I don't wanna live forever
'cause I know I'll be living in vain
And I don't wanna fit wherever
I just wanna keep calling your name
until you come back home
I just wanna keep calling your name
until you come back home
I just wanna keep calling your name
until you come back home

[Verse 2: Taylor Swift]
I'm sitting eyes wide open
and I got one thing stuck in my mind
Wondering if I dodged a bullet
or just lost the love of my life

[Pre-Chorus 2: Taylor Swift]
Baby, baby, I feel crazy, up all night
all night and every day
I gave you something, but you gave me nothing
What is happening to me?

[Chorus: Zayn & (Taylor Swift) ]
I don't wanna live forever
'cause I know I'll be living in vain
And I don't wanna fit (fit, babe) wherever (wherever)
I just wanna keep calling your name
until you come back home
I just wanna keep calling your name
until you come back home
I just wanna keep calling your name
until you come back home

[Bridge: Taylor Swift, Zayn & Both]
I've been looking sad in all the nicest places
Baby, baby, I feel crazy
I see you around in all these empty faces
Up all night, all night and every day
I've been looking sad in all the nicest places
Give me something, oh, but you say nothing
Now I'm in a cab, I tell 'em where your place is
What is happening to me?

[Chorus: Zayn]
I don't wanna live forever
'cause I know I'll be living in vain
And I don't wanna fit wherever
I just wanna keep calling your name
until you come back home
I just wanna keep calling your name
until you come back home
I just wanna keep calling your name
until you come back home

[Outro: Taylor Swift & Zayn]
I just wanna keep calling your name
until you come back home
Until you come back home
