A heart set to flutter

A heart set to flutter.
What meant u by that?
Is it a confession?
A teasing?
A joke?
A hint?

Fool not with my heart,
For its fragility is beyond your comprehension.
Play not with my thoughts,
let not my heart capture nothingness.

Bless me with only kind words.
With only loving acts.
Be it not that my heart should flutter once more.
