In the secondpart, Kaeun talks about debuting with After School, idol styling, whether she would have liked to be in Orange Caramel (note: kaeun was sometimes used as a sub for nana for non-singing promotional activities, though she never actually performed in nana's place), and her hopes for her acting career.
