The up and coming idol group A.N.JELL's management company insisted on adding a
new vocalist to the group as the lead singer since leader Tae Kyung's voice was
starting to hurt. Right before Go Mi Nam could officially join the group as
their newest member, he has to leave to the States to repair a botched eye job.
His agent, Ma Hoon Yi comes up with the brilliant idea of having his twin
sister, Go Mi Nyu, to replace him by pretending to be Go Mi Nam for the time
being without telling the other band members who she really is. Even though Go
Mi Nyu was ready to become a nun, she agrees to this charade in order to help
her twin brother. As the latest "male vocalist" for the idol group A.N.JELL, Go
Mi Nyu must live up to the other group member's expectations while hiding the
fact that she is not Go Mi Nam.
