Okay let me start out by saying firstly, I usually don't watch thriller, scandalous type kdramas but years ago I watched the british drama called "Doctor Foster" and when I heard they were going to remake that show into a kdrama AKA "World of the married" I just knew I had to try giving it a watch. I am SO IMPRESSED! It's slightly different from doctor foster of course but wow I loved it so much, the acting was AMAZING. The added details that was not from the original show was great! I absolutely loved this drama. If you like SKY Castle or Penthouse then you NEED to watch this kdrama. The production, cast, OST, everything in this drama was wonderful. If you want a scandalous, emotional, crazy rollercoaster of a tv show, then please watch this one and thank me later^_^
