Hello
I want to find some with most romance. There are so many to choose from. I'm having difficulties choosing the right ones. K-Dramas are experts and i believe best in the world at doing romance. I haven't seen a lot of K-Dramas. I can tell you my favourite's so far. It is: Revenge (2005), Forbidden Love (2004) and Bad Guy (2010). Each show has lots interesting romance and is well made in my opinion. I hope someone can help me. I would really appreciate it.
you could try ''The Princess' Man'' and ''City Hunter'' since you seem to like a bit of action too.

''Secret'' also has a really good romance
I saw "Secret". It was good. I was going to buy "City Hunter" anyway, but not ''The Princess' Man''. I haven't even heard of it. I will look into it, Thank you.
City Hunter, Healer, That's okay It's love, Marriage Not dating, Angel eyes, Heartstings, Playful Kiss (best romance drama), Oh my Venus, Secret Garden, The master's sun, You're beautiful, Goong.... 

I really love kind of romance drama XD 
If you like melodrama, I recommend Innocent Man. For rom com Oh My Ghost, You Who Came From The Stars, Plus Nine Boys, Princess Hours, My Girlfriend is Gumiho. And for historical Sungkyunkwan Scandal and The Princess' Man
