Lyrics:

Unbreakable heart play your part
In the scheming I have done
Not to fall for anyone
Or let love start

Unbreakable heart it's an art
You will master by and by
'Til then just be my
Unbreakable heart

You may get swept away
Like other fragile hearts
But don't you ever say
Love's breaking me apart

Unbreakable heart don't depart
From the pact that we have made
Love is forsakeable
My unbreakable heart
