'that winter, the wind blows' is my fav of this genre ( though japanese version is better: Ai Nante Irane Yo Natsu), very dramatic. A cuter drama is 'Shopping King Louie' (double life due to amnesia).

My favorite kdrama of all time and for good reason. It leaves you breathless, wanting more. But it has its own peace, even through such seemingly hopeless situations. I learned more about life through this drama. If you liked Bridal Mask this one will be up your alley. It has the hero's journey and fight for justice packaged into a powerful saeguk.

 Jessica:

right up my alley! thanks :) 

Any time! Spreading the Iljimae love :D
