I don't even know how to express my feelings after watching the last episode. I just like it so much.

This is the first show I watch about parallel universe and I like it quite a lot with crime, mystery and thriller involved. I really like the story between Seo Do Won and Han Seo Kyung, even though their fate is twisted and their path to find each other is hard, they're still trying their best to be able to live with each other. I even like the killer's twisted background. How everything is connected also will make you have to really focus on the story and especially the last two episodes. Even though I don't quite like the ending, because it can be a new and intersting story, but I guess it will be too much.

Overall I really like it and I would suggest everyone who like crime, thriller, mystery, fantasy to watch it.
