"Equation" lyrics

You're that one equation
That I can never solve
My inner frustration
Always seems to show

And I know it's hard for you
You're a prisoner
But it doesn't mean I'm not the same
Every time I look at you
It's like a mirror
So I only got myself to blame

Do you need me, need me
Like I need you, like I need you
Do you need me, need me
Like I need you, like I need you
Now, now, now...
Now, now, now...
