25 year old Kim Joonmyeon prides himself in being able to spot talent in the most unlikely places. After all, his agency's biggest star, Byun Baekhyun, was a dreamless troublemaker until Joonmyeon found him, and so was Kim Jongin, the quiet-boy-turned-internationally-acclaimed-dancer.

He's famous for his "Star Cut"-his unique ability to create a multi-platinum record star from a trainee with little to no potential. He cut a worthless stone into a beautiful diamond.

Here enters Kim Jongdae, Joonmyeon's most unlikely project yet. 178cm of jaw droppingly amazing vocal talent and horrible social awkwardness. Joonmyeon has 7 months to turn this utterly impossible trainee into a hallyu sensation.

With the combined powers of Representative Kim Joonmyeon, Composer Lu Han, and Choreographer Kim Minseok, once-ordinary Kim Jongdae will undergo the Star Cut and emerge triumphant...Hopefully.
