Evil.
The word could be used to describe both of you, yet in completely different ways.
You were evil because that’s what you were believed to be. Lucifer’s creation destined to obey the dark lord and cause chaos wherever you go. Born to wreak havoc and taunt mortals to make deals they weren’t exactly capable of understanding fully. You were a temptress from the depths of hell, endorsing the fate you were assigned with.
He, on the other hand, was evil because that’s what he chose to be. Years — millennial even, spent with the belief that he was the epitome of what’s good and pure. The almighty archangel responsible for casting away what’s rotten and tainted. He was supposed to be the perfect prince, yet the path he chose for himself was full of nothing but pain and destruction.
Michael wasn’t good. But you weren’t any better.
You suited each other, the similarities blending together into the dangerous mix. However, it wasn't enough to go through the deep-rooted expectations that were planted ages ago. He was an archangel, and to you, they were nothing but arrogant douchebags with a stick up their asses. On the contrary, you were a demon and those, for Michael, were nothing but filthy pets, created to do all the dirty work.
The power scale here was set in two completely different worlds. Yet, it was probably the main reason why you two were so strongly attracted to each other. You were challenging him like no one else ever, daring to push his boundaries, which the majority would consider to be the utmost insane. And he was this good boy who turned out to be rotten and corrupted, seeking whatever darkness there was.
So it was no surprise when he appeared at one of your crossroads right after you finalised a deal. He was standing a few feet away, dressed head to toe in designer clothes, his head tilted to the side as he stared you down with a dangerous smirk, a hint of insanity showing in his eyes.
