[Verse 1]
I've been all running up night
I've been all running up night
But it's 2am and I can't think about anything but you
I've been all running up night
I've been all running up night
With a tight chest and a conscience I can't get out of my head

[Pre-Chorus]
All I think about is you, you
All the calls that I know you saw but you said didn't come through
So all I think about is you, you
All the things I could say to make you think I'm with you-know-who

[Chorus]
These insecurities
Are gonna ruin me
And I know this jealousy will ruin us
We gotta stop faster than we can run
We are twenty-first century love

[Verse 2]
It's 4am and I don't wanna know
All the things that you are gonna do
Without me by your side
Without me by your side
I've been all running up night
I've been all running up night
With million reasons why
And another million reasons why
