Its disappointing to have to give a low rating to this drama, it started so strong and i felt like it would be one of my favorite dramas ever. The casting is great specially the two male leads, who did an amazing job. Unfortunetely the plot went downhill from the middle to the end of the show. Im still trying to understand some things, like how Ji Cheol scaped for the frist time from a psychiatric institution, murdered Hyeong Bin, was found by some random people and ended up in the prison to be hanged later. They didnt explain that at all! Also, the female lead made choices that were really hard to understand, like rejecting her fiance to be with the man that literally murdered him on their past lives!!! The ending was so disappointing and its sad, cause this drama had everything to be one of the best dramas ever, but somehow they managed to screw it up.
