As reported earlier, Wanna One will be the first guests on the show. As part of the new show, 'Idol Room' will be launching a 'V' live broadcast at midnight KST later tonight (between the 23rd and 24th) for 10 minutes. The number of hearts that the guests receive will determine the number of members that will be present for the ending performance on the show.
The first episode of the new JTBC idol variety show will air on 4:40 PM KST on May 12th. But make sure to catch them when they go live later tonight on their channel.
