A normal high school girl, Yoo Song Ah, has a dream. A dream to become Korea's most famous song writer. Song Ah is the prettiest girl in her school that she is already famous. When she chooses to sign up for Cheong Hwa Arts High School, she is casted into SM entertainment. When SM casted her into a boyband, EXO, it is up to her to continue her high school career in Cheong Hwa Arts High School, or to take the "short cut" to her career of a song writer.
