Accidental Bond

I've made a lot of mistakes in my life, but accidentally becoming a mercenary for a demon might be the biggest one yet…
My inner dragon has always been more like a devil on my shoulder, talking me into making bad decisions and creating chaos. I have a hoard full of demon artifacts, each one likely to cost me my life if the owners ever come after me.
I thought accidentally becoming a mercenary was the worst mistake I would make in a single day… until I inadvertently mated myself to a demon. It's not my fault his mating ring was so pretty!
It'll be fine… all I have to do is fulfill my contract, not do anything else to make things worse, and avoid falling for the surprisingly sweet, himbo demon who thinks I'm his mate. Should be easy… right?
