Shards of Heart For Sale (3:00AM Calls part 4)

You want a human heart?!
Well, not a whole heart...
More like shards of one
You can use it in potions
You can grind it up
Add the shards in whole
Exchange these shards
For something greater
Anything you wish at all
Just take the shards
While there's still shards
Take the heart dust too
Two for one take them both
Please, before he comes back
And crushes my heart more
Please, please, please take them,
Hide them away from him
And most importantly from me
