KBS 2TV's 500th episode of "Happy Together" may (or may not) feature the singer-songwriter IU and actor Jo In Sung.
Jo In Sung, Kim Woo Bin and Lim Joo Hwan were seen at the Gimpo airport in Korea. They were reported to be returning from EXO's concert in Japan. Their pictures were circulated on Instagram where they were clicked hiding their identities behind masks and scarves.
