It was a pretty good drama. Hyun bin played the main lead who has a severe case of schizophrenia and has an alter ego that saves people where Hyun bin himself is laden with guilt from his past and gets strange symptoms like anxiety. I liked all the characters the romance was swoon worthy and Hyun Bin is so handsome. Interesting plot with cliff hangers that keep you engaged. Fun and romantic and hilarious at times. I absolutely enjoyed watching. The female lead started out a little outrageous but seriously this is a guilty pleasure drama so the outrageous stuff didn't bother me.
