Rookie Historian Goo Hae-ryung is set in early 19th century (ish because the premise is ahistorical) Joseon and is a romcom about women being appointed as court annalist-historians. There's court intrigue, office drama, secret pasts, the usual het romance, but the (female) protagonist is really fun and there's a nice supporting cast; what makes it really stand out is that a good half of the time the plot is about the sanctity and independence of the historical record and how important it is to keep it from being censored or corrupted by people in power.
