I don’t write a lot of reviews but this is my first time watching a drama that updates every week and I’m so happy that I watched it. It was so confusing at first with the duplicating and not knowing who is the “bad guy” but I got the hang of the plot and characters later. I think I could recommend this drama to anyone who like science fiction and action since it was fun to watch. I think the only part I was just sad about was that Detective never really confirming who his father was, it was sad to watch. Last episode made me cry my balls out though. Thank you actors, producers, director, and staff making this drama.
