Taken to the Demon Court

Who would have thought that being able to tell when someone lies would get me kidnapped and sold at a demon auction? Before the kidnapping, I had nothing. No family. No love life. No purpose. Then the twin demon royals swept me off my feet right before I became lunch meat. Their condition? Spy on the king and report back his lies. Easy enough. But I never expected to feel the things I did for them so suddenly. Or that it would threaten to keep me in the demon realm for an eternity.
