Jejungwoon is slowly beating The princess man for me. I like the princess Man but Jejungwoon is so much more interesting because of the subject it deals with. And Park Yon Woo just..brings out the humility of his character in such a touching way, I totally love his character, one of the main protagonist there..He's just great!
I also liked the Painter of the Wind, Iljimae and I'll probably like a lot of others when I watch them.
Oh ya! And Hwan Jin Yi and possibly Jewel in the palace and Clothing the World.
EDit: My goodness I just reached 666th post, gotta go post something more, I do not like to be devilish haha
So it's:
1.Jejungwoon
2. The princess Man
3. Iljimae
4. Painter of the Wind
5. Hwan Jin Yi
...for now..
