This drama isn't a drama but a piece of art. Korea should produce a drama that shows us the real thing of how relationship goes. Greedy, jealously, manipulative which hurting the person we supposed to protect, respect and love. Beautiful drama that started fun and quirky but turned to be the most dysfunctional love story in korean drama history. There was no lack, no dragging and no waste of dialogues. The actings are superb for four main leads. The kisses are juicy and and real. I would say, Eric is one of the best korean actor ever when it comes to deliver raw emotions. Even just by watching his blank expressions, we know that he was in so much pain and crying inside. Very awesome job! I like the second female lead more than the first female lead since I know she tried her best to keep their marriage till the end. The background music, the cinematography, the actings all are excellent. This is another level of korean drama. Very artistic. I was like watching movie whole time seeing this.
