The main actor did a great job. The main actress was fine. However, the plots were super messy, irrelevant from the episode 28 or so when she and a man of Devil World fell into another world. I found the drama super boring. I tried to watch til episode 37 or 38 just bcoz of the main actor cuz he was doing super good. But I couldn't really watch more cuz of the messy, irrelevant plots!!!! I decided to stop watching!
I've watched another movie of this kind called "Love and Destiny". The plots of that drama were great, relevant and touching from the beginning. I cried a lot not only bcoz of the scenes between the main characters but also the scenes of her and the family when she was in the second world.
