Yin (dark) and yang (light) are descriptions of complementary opposites as well as absolutes.

You are - white and light
I am - dark and warm

You are crying - nobody sees that
And I - I am scrunching up glass, idiot

You - you love me so earnestly
I, well, I got caught so hopelessly

We - we are whispering secrets to each other
We - we understand everything

But that is not enough

You - you worth of your soul-baring
I - I believe that I worth them as well

You are - a genius, I am a genius too
And if you are searching, it makes it two of us

Pain comes not only from injuries
Fear comes not only from conscience

Funny - not enough surety, as usual

And in the end, I multiply the cigarette butts
And you - you are writing a novel
