Why is it always you?

Why?
Why is it every time I let my thoughts stray,
They seem to stay on you?
What is it about you that make my mind do loops?

Why?
What kind of spell did you cast on my brain
To make it constantly go absolutely insane
Just at the mere mention of your name?

Why?
Don't get me wrong, I don't mind
But I just wonder sometimes
Why is it always you?
