Byun Baekhyun is transferred to the eerie Scottish St. Damon's boarding school, where he befriends Park Chanyeol. Together they will need their sleuthing skills to unearth the truth behind the school's conspiracies, dreams that partially come true, madness, kookiness and maybe even a murder or two. Apart from the sudden feelings he starts feeling for Chanyeol during their friendship, Baekhyun has to deal with a dean with obvious anger issues, a dumb librarian with excellent hearing, a polyglot psychologist who can't speak English and a teacher who claims he only smokes "cigarettes" with students.
