Haeseong and Sundong have to share a room with Rian. Haeseong and Rian just cannot get along. With Haeseong leading the pack, some of the existing Kirin students go to Gangcheol and lodge a complaint about the unfairness of the new room assignment. Gangcheol announces that the rooms will be reassigned based on the scores of the duet performance for the end-of-the-month evaluation. In the meantime, Yujin and JB help Siu and become embroiled in an assault case.
