?Nana addressed the rumors about being an iljin, which is a term often used to refer to the "bad" kids in school, when she was younger.

On the June 19th installment of 'Radio Star', the MCs asked her about her school days, and Nana answered honestly, "I was just very free when I was in school. However, I didn't do anything bad to people." When asked if she had ever had her money taken from her, she said coyly, "I' wouldn't let that happen," bringing chuckles with her frank personality.

However, Nana stressed that although she's a different person now, she doesn't regret her past, as she said, "But I don't regret playing around then. Besides, the past is just the past."
