Cos

-

He was a fool's gold
for her gold bearing
tanned ring finger.

-

You were the sunlight that I loved,
but when you left, I was completely tanned.

-

Banking on my cards,
I played a blind hand,
unaware of the fact,
that my luck is tanned...

-

In the world of,
getting things banned,
Why do I still get upset of
getting tanned.

-

Under the sunlight of her hatred,
The skin of my love was tanned.

-

All i always had was
The sun of worst luck
And my shades of darkness
Life showed different colours
And shades got tanned every day.
