Just loved it

I really will see this drama, this catch me already.
About the first episode I really have to say, hyun Bin is amazing! I'm really happy for his discharge from army.
My first impression of the hyun Bin character was this I will hate him a little , cuz he looks like a person who don't like others people, he is really strange and closed, but this have a explication that made all makes sense. In the first part of the episode he seems a fearful guy, that don't care with other people,but this have a reason. The name of drama already says it, he has two personalities, so when he his heart pass 150 heart beats, he transforms into other guy, but he is not commun like the other people who already had this disease.
Normally who has personality disorder have a love side and a aggressive side, even Seo Jin looks a little aggressive person he is lovely he only acts agressive cuz he is afraid with the other him that can appear, but in the final of the episode the other personality of him appears and it's not a agressive side but a protective and caring side of him, in my opinion this is good, this side is called Robin, he is the fist person who have this type of personality disorder, for me Robin looks like a good person, he already the girl, Ha Na, but for some reason Seo Jin stayed afraid cuz robin are back after five years.
Not to mention a doctor who discovered a recovery for his disease, but she didn't have time to tell him.
Behind of all it have a mystery, and I want now what is.
