Suggest a good Japanese/Korean drama ^^?

I'm looking for a korean/japanese drama to watch ;D Help me, will you?
^^
I've seen these:

1st shop of coffee prince (nr. 1 favorite!)
You're Beautiful
Mary stayed out all night
Bagage (movie)
Hana Kimi
Goong
Boys before flowers
We got married
Absolute Boyfriend
My Sassy girl (movie)
A millionaires first love (movie)
100 days with mr Arrogant (movie)

I haven't seen a lot of jap dramas, so if you know any good, tell me!
_< Maybe cuz I'm not english native ;P It's supposed to be japanese.
