Asian Dramas about Royalty

Any recommendations for asian dramas where one or more of the main characters are royalty or it centers around royals? The other main aspect is that the royalty should be more of the European/western concept of royalty  (these are for my mom who’s into anything about monarchs and royals like the British royalty). 

Examples of dramas like this that we’ve already watched or plan to watch and I’m aware of:

- Goong

- The King: Eternal Monarch

- King 2 Hearts

- The Last Empress

Thank you all!
