Black and White (Nightmare x reader????)

Y/N lives in a world of 2 brothers. Long ago, they were protectors of a tree, one that held both positive and negative energies. Dream, and Nightmare. Dream protected the positive emotions, whilst Nightmare protected the negative ones. These were in the form of light golden apples, and rough looking black ones. Dream was liked and cherished around the kingdom, while Nightmare was often injured by ignorance within the subjects. One day Nightmare got sick of it. He ate a apple. He destroyed everything. Dream and a few allies managed to escape and start their own kingdom. now there are 2 kingdoms. Nightmare's, And Dream's. And this my friends, is where our story begins.

I want to give a big shout out to @childofbears for letting me use their unfinished idea! Thank u so much! So thanks for the adoption! The original title was "A Tainted Love" if you wanna check out the original.
Y/N = your name.
This is also aimed toward a female audience. I would've done they/them, but I was already 5 chapters in, and I didn't feel like changing it.

Cover art is not mine, I will make some when I get the chance. This is also an empire verse story.
