Oh Serena comes home to Korea after studying in America for five years. Her father puts her into the most prestigeous all-girl school in the country in hopes of redeeming her after her stunts in America. There, she realises just how hard it is to get kicked out of a boarding school...and how hard it is to escape a kingka from the neighbouring all-boys school.

Characters: Oh Serena (OC), Oh Sehun, Song Minho, Park Jinyoung (Got7), Bang Minah
