This drama is not really your typical whodunit K-mystery, in fact, the guessing game isn't the main point but this drama is all about understanding the consequences. The first half of the series was superb. Thrilling and emotional at the same time. The acting and character setup were first-class, the directing was well done, and the cinematography was excellent. However, the latter episodes were so draggy and too complicated for its own good. Unfortunately, it falls flat at the end. 6.5/10
