Lee sehun is the host of the ghoul. He is the Director of the Century Pharmaceutical Company and is also a temporary employee at the Century Hospital. He has a brother who is a patient in the Hospital's VIP Ward. Because of their hostile relationship, Lee Sehun lives separately. The ghoul asks Lee what he wants to do when he reincarnates, and Lee replies, "find love" . He also says, "just go find the King of fate" , which is a reference to the fact that the spirit world is no longer interested in him. Lee Seun says that he is not interested in a romantic relationship, and that he does not care where he is staying. He says that his relationship with the spirit is business only, and he will not be interested in anyone else. He asks why he is doing such a thing, and the answer is that he just wants to give someone who does not believe in God some faith. If he accumulates virtue, he gets to reincarnate. He goes on to say that if he accumulated virtue, then he will have a chance to catch the spirit that is making humans sick.
