Mystery. A fascination you share, though not with those around you. A normal day turns unusual when you witness a mysterious incident at a local park. The scene is shrouded in secrecy, and news reports connect this to an unsolved case. You notice your classmate, Sanji, at the scene, seemingly unfazed. The next day, at school, news reports discuss the ongoing investigation. Sanji is late to class, claiming he overslept. Later, in the library, you observe Sanji reading a book on dark literature. After school, you approach Sanji, asking him how he maintains his cheerful demeanor. He accepts a book you offer, and in return, gives you a book on suspenseful stories. You discuss your shared interest in the unknown.
