Both Dramas have a similar fighting/struggling to survive 'against the monarch' plot:
- both MLs are martial artists that have served in the army
- both FLs are smart, headfast, and raise their own businesses from the ground up

Differences:
- JJL has multiple love interests that pine after her as the series progresses, while BIA has only 1 extra love interest other than the ML
- in JJL, the FL is from the royal clan while in BIA the ML is from the royal clan

In both of these series, the female leads are rational and are good at what they do. Jun Jiu Ling is smart and schemes with life as a whole while the imperial coroner does her job well and has a good head on her shoulders for deducting cases but can be a little naïve when not on guard. They portray strong characters to strangers and the outside world but have allow themselves to be comforted by their counterparts when they are having a breakdown.

The male leads in both series express their feelings pretty early on. They both have their own three musketeer group and really trust those around them. I like that both couples work hand-in-hand and serve as each other's support.

Both are great underrated historical dramas that definitely shouldn't be overlooked.
