Hah, yes, I watched the Long Ballad, great drama. And I don't remember a kiss :) but for sure there was romance.
I finished watching Fake Princess yesterday, awesome drama, very fluffy and cute. In the early episodes there was something you would not see in kdrama - spoiler warning:
So after the fake princess married the crown prince, some things happened, and the crown prince comes to the bedroom for "consummation" finding her in the bed with most of her clothes off, even belly bare, smiling at him. This would not happen in kdrama, lol.
