So I'm writing a story with a MC who is like an evil over Lord type he's like Apocalypse meets Darkseid. Anyway his love interest is his bounty Hunter. She is basically like a slave but her service is willing mainly because he saved her from a worse fate. Their relationship is like Pandora and the Hidden One from Sleepy Hollow, my characters they very dysfunctional in a 50 Shades sense. A common theme in the story is him being very ambiguous about his feelings while she's constantly bending over backwards for him while often wondering if it's one sided. I hint he does by having him do small things but at the same time he treats her no differently than any other in her job position.
