Seoul Elite High is well known to be a prestigious private boarding high school for the chaebol family teens. The students are the members of Korea’s wealthiest families, as well as a very slim number of gifted students with scholarships. The regulation in Seoul Elite High is very demanding. In the morning, the students take classes, and in the afternoons they dedicate themselves in improvement workshops, sports and the hectic social life of teenagers. The students consist of mostly children of the richest families, and the limited amount of scholars. “The Oracles” a secret organization or more like a cult that lies hidden within the walls of the school, their purpose is to discriminate against the scholars and scared them away. Rumors about The Oracles are in the whispers, however the teachers believe that it’s just a myth the teens made up. Despite the differences and fights that exist in the lives between Somi, Soobin, Junkyu, and Yewon they manage to unite forces and form a band, given that the only thing they have in common is the love of music and justice.
