It a drama that keeps the viewers on their toes. The twists are really hard to predict. The chemistry between the leads is amazing. And Lee jong suk is a charming male lead with a traumatic past. Even in very serious situation they managed to get some humor in the drama. I personally liked the couple so much I gives you the feeling of something left to be desired. The Father of Han hay joo did a amazing job playing both the positive and negative characters.
The first episode may look a little slow but it's picks up after that and amazing till the end . So it worth of your time. It does seem a little confusing at times but it's fun trying to figure out what will happen
