The midterm exams were approaching so you made the decision to spend some time studying in a library. The first few minutes of studying was going well until some guy was throwing some books everywhere while giggling. This annoyed you and told him to stop but he only stared at you with a puzzled look on his face. He was confused as to why someone would see him since, he was a ghost. He was murdered when he was only 19 years old. You were the first person to see Haru after he became a ghost.
