I have watched till episode 7 .This is my this year 1st drama which I have never skip in the middle . Most of Dramas including Parallel dimension let you confuse most of the time but this one I don't have any confusion . After started watching it I regret one thing most and that is why did I started watching it now bcz 6 days look like month to me . I just wanted to finish all 12 episodes in one go. And about acting as expected you will love YSY more and more .He is great actor . And its my 1st time seeing kyung so jin but she is also doing her best . All of the casts in parallel dimension portrays their different characters in best way which makes this drama more awesome !!
