K- drama: You are Beautiful (You are Handsome) . Go Mi Nam, whose name literally means “handsome,” has it all – good looks, and landed a place on the teenage idol boy band A.N.Jell. But when a plastic surgery procedure gets botched, he is forced to secretly go to the United States to have it corrected. His agent asks Mi Nam’s twin sister, Mi Nyu (Park Shin Hye), to pose as Mi Nam and take over his place in the band. That is when trouble starts since the members of the band and people around them always assume she is a boy.
It reminded me a bit of Ouran High School Host Club.
