The school's three most popular guys are actually someone's exasperating brothers—and someone who loathes attention at that! Haejoo craves a life of mundanity and obscurity, but she's plagued by her three jaw-droppingly handsome brothers who stand out even when they're doing nothing more exciting than breathing. At school, she goes to great lengths to hide the fact that they're related, but what happens when she finally gets busted?
