I started watched this drama, because I need some thriller drama. And i found this one is interesting. I finished in 4 days. The ending is so unexpected. The cast are good. But, if you don't like a drama with some affairs , so don't watch it. This affair is different than other affair. I like the wife very much, she's smart and brave. She can expect every in details. And this drama makes you curious in every episode. I was not too excited for the 1st to 2nd episode, but 3 up it's get more excited. Some episode makes me dizzy about the scene like they are repeat scene and situation. But, I still love this drama, and the ending was good.
