All Kum-Ji desires in life is to encounter her favorite boy band, DDL. Upon discovering that the fan club roster is full, Kum-Ji despairs of ever getting the chance to meet them face to face. Just as she believes all hope is lost, she decides to con her way into the boy band circuit by faking an interest in another band, Yo-I, and joining their fan club. Once inside, she will have access to other bands, including her beloved DDL, who often plays the same shows. However, the best-laid plans so frequently go awry, and her deception is very quickly discovered by one of the band members, E-Soh. E-Soh originally decides to blackmail Kum-Ji into doing whatever he wants, but he never planned on falling in love!
