After Chuno, I recommend Harvest Villa, a modern mystery and a superb confidence game drama that will leave you impressed as well. For all the many fans of Jang Hyuk, I suggest "Midas," where high finance and international finance is the background for an interesting power game, where the top 1% of society is pitted against the rest. These two shows are sophisticated adult entertainment and prime examples of the quality of the K-dramas. Once you start with the first episodes there is no stopping, a real test of an absorbing and quality series.
