Fulfillment and it's Opposite

Knowing myself to be the bane of his existence fills me,

not with pleasure, or pain, but pure emotion.

A watery substance only defined by what it contains,

in its cleanest form, nothing, it is nothing, is filled with nothing;

Yet it is there.

How can something fake be defined?

Even in the definition it must be unmasked,

or it has yet to be defined, a watery substance.

But it is like water, this feeling, not water.
