This Must Be Love

I'm smiling at my phone
I'm singing in the car
I take the longer road
Just to pass where you are
I never used to act this way
But look at what you did today
My heart beats faster when you call
I miss you before you even go
If this is what
I've heard about
This must be love
I wake up early to see you first
I steal your
T-shirt
And wear it to work
My friends keep laughing when
I say
There's nothing going on this way
My heart beats faster when you go
I miss you before you even go
If this is what
I heard about
This must be love
I know you're coffee, you know my song
A day without you suddenly feels long
I think
I finally understand
Why everybody wants this feeling
I don't need anyone to tell me
I can see what
I've become
If being this happy has a name
This must be love
This must be
This must be love
