I don't like rich man poor woman drama at all. From the list you mentioned, I watched Descendants of the Sun, Healer (these 2 were my very first 2 kdramas, I was introduced in this world in college, by 2 of my classmates), Weightlifting fairy Kim Boo Joo, It's okay not to be okay and Something in the Rain (these dramas I seoected by myself Actually my type is non-egoistic men with their own minds or innocent and honest men and yeah of course I loved the romance.
I have always known about the other dramas, I read synopsis or watched some clips and I don't want to watch them. I can't watch any drama/movie lacking a powerful/humanly female character.
If I am to talk about some of my most favorite kdramas, they will be: The King's Affection, Extraordinary attorney Woo, The Queenmaker, It's Okay not to be Okay. I quite liked Weightlifting Fairy and Strong Woman Do Bong Soon too, but then I was in my late teen.
My colleagues mocks me so much because I watch kdramas. I don't watch them that much now, my watchlist is more widespread now, given now I can afford and hence have Netflix and Amazon Prime subscription of my own. But they hate me so much and so illogically. I asked them today if they ever watched any kdramas, and they said no. But they saw clips they said, didn't say what clips, but they found them too unrealistic and setting a very high expectation. Now the female colleague stopped just saying that these dramas are unrealistic, but the male colleague hate me with all his heart for watching kdramas, and he just went on saying these dramas set up such high expectations. I told him that there is a plethora of kdramas, all are not the same, I asked exactly what he is referring to, because I also know and hate many toxic sides of the kdramas, many of them set such toxic beauty standards; shows peer pressure, bullying, turning into a beauty from ugly duckling in such toxic positive lights; worships the handsome male ceo etc... But I hate those dramas with all my heart, honestly, I can't care less about those dramas. But when I say I love kdramas, I am not even thinking about those dramas, I don't consider them as dramas. But this guy just bullies on and on, without explaining what he hates about the kdramas.
And I have known him for almost an year, he is the average misogynistic guy, so am pretty sure he hates the caring and feminine side of the men shown in the dramas, that that's the most or at least one of the most hated aspects of kdramas to him. But I just want him to stop that nonsense bullying and come clean.
