Rookie Historian is not completed yet, but it already reminds me of this drama not just for the time period, but the strong female lead and prince pairing. Both are also noona romances which is a bonus. :)
These have very little in common on the surface in terms of plot and time period, but they both have insanely competent female leads fighting to keep their independence and their careers. The male leads are also similar since the are really sweet. Both are also noona romances.
