You are my double
somehow, I am your trouble
You cast the dice
You became my worst vice
I am your adverserial
your commitment is my surreal
in appearance
i may be your shadow
in reality
you are merely my puppet
Or, it could be
You may be the executioner
whereas I am to beheaded
As my body fluid and blood
stain you
we become one
when my hand manipulate the strings
as a puppeteer
we become one
Un duetto/une duetta?
