Hyunjin has been in a private mental hospital for about two or three months. he is a particularly violent patient, also a crazy one, who suffers from paranoid schizophrenia and bipolar disorder. Hyunjin had quite famous and rich parents, and even if he had a younger brother, but it was Hyunjin who was mentally ill, and not someone else from his family. Hyunjin doesn't trust anyone except Felix, his psychiatrist. Hyunjin hated the pills the nurses gave him because they tasted bitter and had terrible side effects, but he did not resist when Felix gave them to him.

Felix quietly knocked on the door of Hyunjin’s room and went inside. Hyunjin smiled widely when he saw Felix and chuckled loudly while sitting on the bed, tucking his legs under him. "Oh, Felix, come here! It was so boring and worrying without you..." said Hyunjin with a wide grin, looking at Felix with empty, sharp and lifeless eyes that seemed ready to kill at any moment, but that’s not the case..
