best SAEGUK ROMANCE dramas!! recs please

I've seen a lot of sites with drama recomendations for romance saeguk lovers, but wondered what drama mdl users would suggest.

please with happy ending and I find older dramas better and I prefer more serious dramas, but lighthearted ones are fine once in a while.

dramas I've seen:

the princess' man

the crowned clown

moon embracing the sun

the bridal mask (not sure if it counts as a saeguk though)

100 days my prince

the forbidden marriage

king2hearts (not sure if it counts as a saeguk though)

the legend of the blue sea (partially a saeguk)

So many. This is just a list of what I watched, the asterisks were the ones I thought were the best

Moon Lovers*

Faith

100 Days my Prince

Arang and the magistrate

Bloody Heart*

Hwarang (though I think this is more of a "fusion" thing)

Mr Queen*

Poong the Joseon Psychiatrist (2 seasons)

Kingdom* (2 seasons)

Sungkyunkwan Scandal 

The Forbidden Marriage 

The Red Sleeve 

Under the Queen's Umbrella*

I differentiate historical kdrama (saeguk) into two different categories.

Normal historical kdrama, like mentioned above.

And then there's these big saeguks, that cover historical facts or person and are often very lenghty (50-60 episodes)
