Minami sineyo (2009 - 2009)

Min-ae is a kind, trusting, and charming girl who grew up without parents alongside her twin brother Min-nam. As she grows older, she dreams of going to Rome and becoming a nun, while Min-nam chooses a completely different path - the rocky road of a pop star. He hopes that success and fame will help him find their mother. But one day, their music manager tells Min-ae that her brother can't perform temporarily and they urgently need to find a replacement. Who truly resembles Min-nam and sings beautifully? Only his sister. Pretending to be a boy, the modest and obedient Min-ae becomes the new member of the super popular K-Pop group. Until her brother returns, she must keep her secret, but it's even harder to get along with the lead vocalist - the arrogant and moody Tae-hyun.
