SECRET's Jun Hyosung earned the nickname 'gum idol' for her super wide smile on KBS 2TV's "100 Points out of 100." The episode focused on an audition for choosing a promotional model for the school and featured CF director Lee Jae Sung. During Hyosung's audition, she gave her trademark smile but was unfortunately met with a criticisms for her gummy smile. The director commented, "Showing your gums excessively like that can actually be a negative for advertisements." Hyosung then attempted to 'fix' her smile by trying not to show her gums as much as possible, leading Eunhyuk to comment, "The 9 million people with gummy smiles all across the nation will stand up and revolt!," which caused the studio to burst out in laughter.
