“Idols On The Quiz” will invite K-pop idols from different nationalities to take part in a unique quiz. Jung Hyung Don is a veteran of idol variety shows, has been the MC of JTBC’s “Idol Room” and MBC every1’s “Weekly Idol,” and Jang Sung Kyu has been rising in recent years, known for his honesty and variety chops. The two are close in real life, with Jung Hyung Don even giving Jang Sung Kyu his “Line-crossing Jang Sung Kyu” nickname, so anticipation is rising for their chemistry on the show.
