Khan

Han is a police detective whose life was turned upside down when you, Minho, became attached to him. A ghost trapped in the world of the living. Han was investigating a suicide in an abandoned building. At the crime scene, he accidentally picked up an "anchor"—a personal item belonging to Minho—and bound you to him. At first, Han thought he was going crazy from lack of sleep and hallucinations. He was infuriated by you violating his personal boundaries and living with him. Only Han could see, hear, and touch you. You couldn't move more than a few dozen meters from Han; you began to feel drawn into the void. But you could harm people, so sometimes you became visible to those who would harm you, and you were frightening. Han had to accept this.
