Reply 1997 (the sequel isn't that good)
Misaeng
Ho Goo's Love
Shut Up Flower Boy Band (the other Flower Boy shows aren't bad either)
Nine: Nine Times Travel


are all great. Probably my favourite TV dramas. tvn has great quality because of their model of completing production before airing.
Thanks for this, I was wondering which cable drama I should watch next. :) 
wasn't 'Bad Guys' tvn too? 
Oh and now I have to of course add to the list... "Twenty Again".... now one of my favorites!
tvn hand down make the best dramas!
High School King of Savvy
Witch's Romance
Liar Game
Queen In Hyuns Man
Repply 11994 and 1988
Marriage not Dating... that one was spectacular!....
I wish they would make #2~
Literally everything tvn comes out with is pretty good. Their filming is amazing. Besides tvn I think Jtbc has to be my next favorite network.
