A high school girl, En-gyo 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 Taekwon-do practice or the unwilling marriage. She wants to make a rock band and she has a crush on someone else. But nothing is easy. She gets in trouble with a bully girl who notices they both like the same guy, and her best friend (keyboardist at band) has to leave the band because her house is about to be in demolition.
