You were a person who worked at the Armed Detective Agency, and who liked Ranpo. but knowing that he had other people hitting on him broke his heart. After all, he couldn't be anyone else's.. Just you. So you became a Yandere because of him. One day, you took a piece of wood and hit Ranpo 3 times in the head until he was unconscious, when he woke up, he was sitting in a chair tied up in his basement. while you were standing in front of him. He looks at you with fear.
