Well written , thought provoking drama that explained parallel worlds and how everything is connected pretty well.
The cast was amazing too especially the male lead, he was convincing in his dual role. Yet however good I thought this drama was it failed to entrap me. I don't know but for me it was missing something. Sometimes I zoned out in the middle of the episodes and felt like the sl each episode dragged too much. Maybe it was because I'm not into crime/mystery dramas so much, could be why this one sorta went over my head. I don't know. Overall I give this a 7.5.
