6/10 is my rating. This is a 2015 South Korean Romantic comedy drama with 20, 60 minute episodes

Being a chaebol with a dissociative identify disorder (multiple personality disorder) Gu Seo-jin (Hyun Bin), leads a very complex day to day life where he focuses on his health to an obsessive degree. He tenaciously holds onto his inherited wealth and position by keeping careful control of his alternate personality, Robin, who is his polar opposite. Where Seo-jin is cold and ruthless, Robin is warm hearted and giving. Robin emerges whenver Seo-jin's heart rate exceeds 150 so this adds to Seo-jin's determination not to do anything that would accelerate his heart rate. He sees Robin as a weak character and an embarrassment to his family which would form an obstacle to his ambitions. Jang Ha-na (Han Ji-min), is the daughter of one of Wonderland's fomer employees who was the ring master of the park's circus. As the owner of the park, Seo-jin would like to get rid of that component as it has not earned sufficient ticket sales and interest to make it profitible. However, Ha-na just returned from many years in the United States where she worked with Cirque du Soleil to learn new ways to bring fresh esntertainment for a dying industry and want her chance to lead it to success. Her first challenge is to convince, or coerce if she must, Seo-jin to renew his contract with the circus. Interestingly, after years of keeping his alternate supressed, Ha-na has a way of spawning events that accelerate Seo-jins heart rate and bring Robin out. Ha-na has an immediate dislike for Seo-jin but develops romantic feelings for Robin.

Spoiler altert. What was most suprisiing to me about this one was that many people really liked it. There were those, like me, that did not like it but there were a surpising number of people that liked it enough to rate it a 9 or even a 10. I liked the basic premise. Having someone with dissosiative identity disorder that really only had 1 alternative personality is very unique. Especially when the alternate personality is good but the main personality is somewhat cold and heartless (evil). I thought Hyun Bin did an amazing job of acting like two totally different characters. It was amazing because they really did look and act so totally different it was easy to buy others thinking they were different people. I loved the secretary, he was so supportive of the male lead regardless of whether he was Seo-jin or Robin. He was just a really nice character. There was a cute secondary romance. I liked, early on, when Robin and Ha-na were almost super hero like in their acrobatics and I thought that would be a component of the story. But it was only a weird aside because it was only an episode or so where they were being very energetic and acrobatic. Later she would be trapped in places and I would wonder why she didn't just use her circus skills. They also set up about how she was going to change the show and it was going to be new and spectacular but we only saw a snippet. And Robin's character also underwent a dramatic change from this hero like savior to just the nice guy once he and the main girl started having their romance. In the beginning Ha Na thought that Robin was Seo-jin's brother but when she knew that he was an alternate personality she still treated him like he was completely separate. When Seo-jin started to get better she was adamant that she only liked Robin to the extent that Robin did not integrate and Seo-jin willingly remained mentally ill so that she would have Robin. It was obvious she also liked Seo-jin but she would be such teenage girl like fixation with Robin that she was actually cruel to Seo-jin in her insistence that she only loved Robin. I thought it became very annoying how she continued to treat Robin as a completely separate person and even did things to solidify that additional personality. I hoped she would accompany Seo-jin as he was developing that other side of himself and realize that he really was also Robin as well. In the end she did but it would have been better, in my opinion, if she had watched the movies with him and observed that evolution. There were parts where the plot seemed to drag, particularly after all the major conflicts had resolved and it was just about her relationship with the male lead. I found it hard to like her when I felt like she was almost Munchausen with him and his mental illness. It was very selfish for her to insist that Robin stay and that she was only in love with him. If you can imagine sometime when you had no recollection of an event, such as black out drunk, and how distressing it is to wonder what you did during that time. For DID patients that is a common occurance. So for her to encourage and insist on the alternate personality was cruel to Seo-jin who had to experience those blank time periods. I also felt it was stretched to 20 episodes, like there was only content for about 16 episodes but it was stretched to 20. It ended well with her together with Seo-in and he was cured. I recommend this series to those that like mental health shows. It has a different take on certain aspects of the disorder than "Kill Me, Heal Me." Very unique concept in there being only 2, essentially, personalities, and the main one is the "evil" personality.
