I want to be the only world

You will always have a million worlds
Trapped inside that mind, heart.
Those eyes -
I have read a few times;
They always seemed true for as long as they were before me
But because you have a million worlds,
And I am but oneā€¦
I will never know which of the 999,999 you inhabit the most,
For we are often 9,343 miles apart.
