Synopsis
Min-ah discovers a purple diary. As she reads through the pages, she realizes it is a journal exchanged between Hyo-shin and Shi-eun. Hyo-shin's sudden death evokes a series of strange occurrences. Eventually, the school is transformed into a place of morbid carnivalesque, as if “Memento Mori'' written in the journal meaning, “remember the dead” has come to life.
