This is soooo... amazing drama .if you like to watvh the drama with doctors and mysteries happening at the hospital you definetly have to watch it . If you are a type of girl who love the male lead who dont care about others then this drama is definetly for you......he take pride on his skills. He had a problem in frontaal lobe due to which doctors said that he would be unable to feel any emotions .but his only father help him to learn body language so that he could communicate with the other people . The drama starts with him as a doctor .he doesnt care about patients .he has no sympathy.he do what he wants to do.he works in the same hospital as his father but he doesnt even care about his father.on the other hand there is a police officer ,ofcourse she is the female lead ,who is really ambitious about her work .she is a traffic polce officer but she wants to be in crime division.later in the drama during solving different cases they both meet frequently in the hospital .also because the patients were dying one by one who had the same hear problem .then they both together solve mystery .throghout the story doctor lee is just too incredible he is perfect.he is more genius then anyother surgeon . The only thing he dint learn was the gestures of love .so he wasnt aware of it .but after many events he realizes his affection towards officer gey just because she thinks of him differently.everybody in the hospital calls him a pshycopath afterits is revealed in the hospital that he is unable to feel any emotion .but she helps him to sympathize the patients and love. Thats all i could tell .but this drama isnt so straight forward as i described .its is much more complicated and has a lot of suspenss and love .
