Great acting from the leads, amazing chemistry between Hyun Bin and Son Ye Jin. I have always admired the acting of Son Ye Jin and she was super good in this drama. Supporting cast really good as well:) The OST is the best! I love the story and very well directed and cinematography will WOW you! So much following here in the USA. This drama is globally successful. Please don't compare CLOY to Descendants of the Sun coz there's a big difference in the acting and the flow of the story and overall it's much better than any other k-drama. You will definitely enjoy watching the show from beginning to end:)
