Kill Me, Heal Me
Chief Kim ( Hilarious comedy with some wonderful characters and not one but three fantastic bromances) 
Weightlifting fairy ( One of the healthiest and swooniest depictions of a relationship in a korean drama, a great heroine that has a complicated web of relationships, multiple storylines and is allowed to shine instead of being delegated to the love interest, beautiful secondary characters and a great message)
Circle/Signal/Cruel city some of the best dramas out there, in terms of over all quality when it comes to the trifecta (acting, writing, directing) not to be missed.
