Byun Baekhyun is a teacher's pet, in ways he would rather not be. The teacher? A young man named Kim JongIn, aka Kai. As if this wasn't enough, Baekhyun's also the the target of Oh Sehun, the one of the most popular guy in school's, affections. To top it off, things become real heated when a new boy named Park Chanyeol transfers to his school. Byun Baekhyun is definitely not looking forward to this school year. Nope, not at all.
