There is one time during twilight when meet two lovers
and discreetly, behind sunset's cover, they first
must dance round each other's girth  
under dusky sky then, in russet-style soon couple.    

Sparks fly as Dark embraces Light for at his touch stars
rush to the scene, blue blushes red at confessed
union, hues meld in wild expression
before Dark has to stay and reluctant Day departs.

Grey is then dominant shade as waits setting silence
with bated breath until comes change to wrench
paired bliss again as rays descend
'til morning breaks loose from ******* to night.

When Dark and Light next unite dawn knows well
it will be but moments before their goodbye      
but used to addiction hours will fly
toward  flickering chance as time ties them again.
