The tale of my beating heart

I heard someone say,
As I was walking aimlessly today,
Does your heart beat for the one you love
or does it simply do it's bidding in your body's glove?

For I said to the stranger,
There isn't any danger,

For my heart beats only for one,
Though he doesn't feel it that way,
And even if I were ever alone, with my last breath,
I'll love him forever and a day, even in my death.
