Plot
After the unusual attack (tossing of a bag of feces) on a school 'flower boy' (heartthrob or pretty boy), Sungmin, on February 14, the same attacks begin to happen at different high schools on every month of the same day. Rumors say that the next victims will be at Neulparan High School. The studious student Kibum decides to investigate the matter, blogging all of the terror events on the 14th of each month, causing the event to become a hot topic within the student body. After several attacks, Kibum predicts that the next victim will be either Siwon, president of the student body; Heechul, president of the dance club; or Kangin, the captain of the Judo Team.
