not sure, I hope there's one too, there's a novel about a
hitman, but the top is the target, not the person who hired mc (idk why mgg cuts my comment off tho)

Not exactly hired, but its mercenary x duke
Plaything
I wonder if there is some bl out there (well,pretty sure there is) where it's an assassin/hitman x the person who hired them
