Seoul School Murders

Fifteen years ago at the Seoul School of Arts and Music eight young men died. All of them died suddenly and unexpectantly and all died within the year starting from a couple months after the start of the year. Their killer was never brought down. Now Jeon Jungkook a first year student at the university in question sets out to find out what happened to the eight students and why no one was ever convicted. He's heard the rumors and stories and wonders just how much of what he's heard is actually true. He is eventually joined by six other students, his new friends, Namjoon (who doesn't believe in ghosts), Seokjin (Who thought they weren't real but is starting to believe), Yoongi (who believes since going to the school), Hoseok (who believes and has an ability), Jimin (who can see ghosts) and Taehyung (who can feel ghosts but not see them). They soon enough discover they may be in danger. Will they solve the case from fifteen years ago? Will they all make it out alive?
