Good Kdramas Netflix / Viki?

Do you know good Kdramas that you can watch on Netflix or Viki, because I have no idea which I could look at. I definitely like romance and comedy, but I'm actually quite open to everything. Such as.

My Holo Love, Love Alarm, Romance is a book, My secret of my secretary, Abyss or Two worlds Apart.

I hope I could give you a little insight into what I like.

Have you ever looked into "W"?

On Netflix: 3

Yes, but thanks anyway, I know from a friend
