Good dramas that are currently airing (or already have this season)?

Currently Im only watching heirs. What are some other good dramas that are airing?

I like Doctor X2 - 6 of ? episodes have aired. (Or have been subbed and uploaded to GoodDrama so far, I should say.)

Today I watched the first episode of Umi no ue no shinryojo. 7 of 13 episodes have aired.

Both are medical dramas, but different from each other! Both are funny, but I'd say Umi no... has more comedy.
Doctor X2 has a cool female doctor. Umi no... has a goofy male doctor, both of them are very skilled.

I second Empress Ki and Reply 1994!

Reply 1994 - totally related to life

I would also say Empress Ki, it's wonderful but there are not many episodes out yet, so maybe you should watch Reply 1994 first

the prime minister and i! :)

Man from the stars starts airing on dec 18, looks good from the trailers ^^

The King's Daughter, Soo Baek Hyang is my favourite drama right now. Also really loving Prime Minister and I :) All the jdramas I've been watching this season are rather disappointing, especially Ando Lloyd. As for twdramas, In a Good Way is having a nice start.
