Your Heart For Mine?

everybody has a secret:

kept as bloody wine in a barrel,
you will know mine on my death.
Force met with force.

It is bloody wine in a barrel:
rot with me, ferment!
Force met with force.
you will rot with me.

Rot with me! Ferment!
My secret is in my heart:
you will rot with me,
till death do us part.

My secret is my heat.
And you say you wish to hold it?
till death do us part?
when the rot sets in.

You say you wish to hold it,
but your hands will decay,
when the rot sets in.
Bleed with me, then.
