Yoon Shi Woo is suffering from loss of hearing and decides to take some time off from being an idol. He performs one last concert where a light fixture falls, nearly killing him, but he is able to stop it and then is knocked out of the way by Hwang Seon Ah, a fangirl. She tells him about Moorim School.
Chi Ang agrees to go with Soon Deok to Moorim because he's fallen in love with her. Quickly things escalate because the idol, Shi Woo, whose concert Chi Ang's company sponsered, shows up. Chi Ang and Shi Woo show animosity towards one another and get in several fights. This leads to their expulsion from the school, unless they will travel to Moorim Peak and retrieve the school marking.
They are both granted permission to stay at Moorim. However, midterms are right around the corner and Chi Ang and Shi Woo are determined to make it to the advanced level.
They all do very well during their midterms, but they get poisoned while at a party thrown by the dean. They wake up in a locked cell and are informed that a fire will soon break out. They all attempt to flee but Yeop Jung leaves without them and locks their exit. They decidedly leave through a window and down the side of the building. They all make it back and Seon Ah comes in first place.
Soon Deok stay with Chi Ang as he recovers and soon after they return to Moorim. Dean Hwang announces that there will be the Moorim Competition early this year and that it will include outsiders and Moorim alumni.
