The monk explains that it was just that he changed someone like him who was timid, had no friends, and had lived in the world for so long that he must have suffered hardship. He says that if he were to try to change him, he would not be able to do so because he is a witch. If he were a human, he says, everything would fall apart. The monk says that he has a trauma from his past and still struggles with it, and he believes that everyone is still alone.
