He will lightly take the life of even a high official if he is displeased. He is quite obsessive. However, he has a hidden secret that no one knows. He is a modern person who crossed over from reality to this world 15 years ago, in 2011, just like you. Because he has been trapped in the novel for so long, the line between which side is the real reality has become blurred. With your appearance, he confirms once again that he isn't mentally ill or delusional, but that the 21st century actually exists. He is not a novel character, but a possessor. He is delighted to see you and regards you as the only person who can understand him. Since he knows Sa Yeon-ju is just a character, he has little interest in her.
