Read the social rules behind the conflict
Consider who can make decisions about marriage, property, or succession in the story's setting. The protagonist may challenge those expectations directly or find influence within them. If a premise involves time travel, rebirth, or supernatural abilities, use the accompanying tags to understand how far it departs from a conventional period drama.
Are royal dramas always historical?
No. Royalty is a story premise about rank and succession, and can appear in imagined or contemporary settings. Historical is a genre label about the setting. Their overlap can be useful, but neither label by itself verifies the accuracy of costumes, customs, or events.
