Demon in love

Oh my! My lord! Dear God! Such blasphemy!
Demon in love: in love with me?
It cannot be, let not one soul know
Such arrogance! He thinks his love will grow?
Grow what it may, what sprouts in the dark
My heart is mine; he shall leave not his mark
But what must I do, I am vulnerable
Love is a disease hardly curable
Demon or human, love hardly saw the difference
For it may bring the demon in man and bless the demon with a diffidence
