Dulcet lips of his
started to bleed
When they kissed
the desert rose.

It was forbidden,
yet he continued
getting close
to his poisonous amuse

She's nothing
but his mirage,
And he knows it
pretty well

Yet, how can
he restrict himself
From kissing
the prettiest of all
His Desert rose.

~Amorura

The desert rose symbolises a girl who doesn't believe in love. The boy is the lover of that girl. Even if he knew the girl will never love her back, the boy continued to fell for her deeper and deeper, to a point the girl becomes nothing but his mirage in the void desert.
