A student, as a sophomore in a great high school, who meets an annoying badass sport teacher, with trait of Dokko Jin but the look of Athena’s Son Hyuk (Cha Seung Won) and at the same time she meets a cutie band teacher (Lee Dong Wook). At first she developed pretty good relationship with the sport teacher, but then the teacher’s Dokko Jin-ish trait brought twists and problems. A story that would develop into a complicated story?!?
