The drama is definitely unique. The director went all out with his own style. Not necessarily objectively good nor bad just different. I personally enjoyed what it tried to do. The quirky direction is the drama's biggest highlight. There were no eavesdrop where characters happen to stumble upon a secret, instead there are very long extended cut open dialogue scenes with no interruption which makes all the difference to see the characters actually talk. Some episodes may consist of only two scenes for this exact reason. The drama doesn't shy away from throwing experimental scenes that are completely unrelated to the story for fun. Although some scenes are just too bizarre like that one scene where an old lady reminiscing a young guy's body after the funeral. These scenes will probably make most of the characters seem insensitive. Then there's ep79 coming out of nowhere completely unexpected! The characters sometime step outside the boundaries of their character and do something unlike their character. This also resulted in inconsistency and showed the characters in a bad light. At least the drama doesn't attempt to "fix" the character, sometimes it's okay to remain broken. I ended up enjoying the drama for all the wrong reasons and that's cool. I liked Ha Na as the antihero, she did great and it might be her best work so far.
