Cinderella type kdramas

Looking for kdrama series that have that typical cinderella-story concept, a poor girl meets a rich and powerful guy, chabol, prince, king etc.

The poorer the girl is and down on her luck the better.
The richer and more powerful the guy is the better.

There are kdramas that feature maybe a middle-class girl and a upper middle-class guy, e.g. part timer meets a doctor or something like that, or lawyer girl meets small time chabol, but I don't want those kinda kdramas. I prefer kdramas that feature a princess like transformation for the girl.

So far I've watched these that fall into this category:

(from best to least)

Goong    (perfect example)
My Princess   
Cinderella and the Four Knights   
Empress Ki   
The Last Empress   
Secret Garden   
Lie to Me     
My Secret Romance   
Something About 1 Percent   
Prime Minister and I   
The Master's Sun   

Hope my list helps.

1. Devilish Joy

2. I Am Not A Robot

3. Rich Man Poor Woman (Original Japanese version is better than the Korean remake)

Old Dramas

1. Lovers in Paris

2. Hotelier

3. Lovers in Prague

4. Firebird/Phoenix (Korean)

Here are some k-dramas that I think fits the bill:-

• Scent of a Woman (2011)
• Marriage Contract (2016)
• Fated to Love You (2014)
• Cunning Single Lady (2014) - (storywise, it's not during their first meeting but after their divorce that the ML becomes rich)
