Welcome to Seoul University of Preforming Arts or Supa as the residents call it. This is where a group of normal but very hot boys have a rivalry going on. Kris and Sehun have been enemies since the first day of school and their animosity even extends to their friends. The only thing tying these groups together with civility would be Junha, Suho's little sister, and her best friend JaeNi, also the best friend of Tao. But what happens when two newcomers appear and the whole rivalry goes topsy-turvy? Who falls for whom, will old acquaintances reunite, and what's to become of the biggest rivalry on campus ever?
