Chained heart

You've chained my heart too long
I've lived in darkness for years
You made me forget my only song
Weren't you supposed to dry my tears?
Now I'm gonna go away, far from you
You will knock on my door baby blue
Wearing our engagement ring
Begging me for mercy on your knees
Swearing you will do anything
Crying and saying: "forgive me, please"
It will be too late for everything
You've been my mortal disease
I hope one day you'll see
All the pain you've caused me.
