[Verse One: 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 One: 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 Two: 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 Two: 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 and 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 and Zayn]
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
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 and Zayn]
I just wanna keep calling your name until you come back home
Until you come back home
