On the November 9 airing of MBC Everyone's 'Weekly Idol,' the idol MCs on the show were GOT7's Jackson, MONSTA X's Jooheon, and TWICE's Dahyun. The two main MCs, Defconn and Jung Hyung Don, tried to figure out all their relations.
While Dahyun is a label mate junior to Jackson, who is friends with Jooheon, they couldn't figure out the link between Dahyun and Jooheon. Jung Hyung Don asked, "Are you two close?" and Dahyun revealed, "To tell the truth, MONSTA X's Jooheon is a church oppa from a while back." Looks like they knew each other since before debut!
