What if the person that you just talk to, never existed or at least 8 years ago? Hwang Hyunjin - a young psychiatrist with a little of experience but great knowledge gets to know Lee Felix - the CEO of the huge corporation. He has to examine and tell if he wasn't too aggressive to his workers who complain a lot about him. His examination will tell if any specific illness is there but what if this person is just playing games with you? What if he is smarter than you? What if his past is sealed with his life and he will do anything to keep it there? Hyunjin is lost, is he really talking to a phantom? Why he cannot let it just go?
