Gu Family Book perhaps, I'm watching it now and it's really addictive?
I had the same feeling after watching The Princess' Man, see you got that one on-hold though.
The first few episodes may be a bit boring with all the talk but I promise you it's one of the best dramas out there.
You could also try something completely different, perhaps something without romance as the main plot. Like Clone Baby. It's one of those dramas where you get thrown inside the plot right away instead of having slow first episodes. The first episodes being boring is what usually pulls me off. You could also try City Hunter if you want to try something with action but also romance. And if you prefer something korean.
If that doesn't work either you can try out some of the classics. For example Boys over Flowers (or hana yori dango, I personally liked this version better), Hana Kimi or 1 Litre of Tears.
