I love this drama, it is the second K drama that i watched during the pandemic, it sealed my fate as a K drama lover. It is a refreshing take on thriller/action/mystery drama with a side of romance. i first saw Ji chang wook in this drama, and have been fan of the handsome actor since. His acting skills are amazing, he really brought Seo Jungho to life and also Park Min young has pretty amazing acting chops. The leads have have great chemistry, you can't help love this cute dorky pair. You have to have a little paitence for the mystery to unravel but overall really great drama, no unecessary break ups and melodrama between the couple, the other characters are really well written, great action scenes even if the ending is a little rushed. not to mention the OST of this drama is amazing.Definitely a recommended drama for veiwers especially for newbie k drama lover. i consider this a classic K drama of the Last decade.
