A high school girl, Engyo is raised from a Taekwon-do family. Unlike her mother who got married to her father against the will of her grandfather, she is forced to marry the guy her grandfather chose. But she doesn’t want either Taekwondo practice, or the unwilling marriage. She wants to make a rock band and she has a crush on someone else. But nothing is easy. Engyo gets in trouble with a bully girl who notices they both like the same guy, and her best friend Yunbi(keyboardist at band) has to leave the band because her house is about to be in demolition.
