It appears as though VIXX’s performance was pre-recorded (prior to the “Idol Star Athletics Championships” filming) due to their scheduled appearance on the Manila special for “Show Champion.” VIXX’s Leo did not go to Manila with the rest of his members and is still recovering.
The group performed their goodbye stage for “Fantasy” on “Music Core.”
Previously, Leo suffered an injury to his nose during a futsal match for “Idol Star Athletics Championships.” Although his agency assured fans that the injury had only caused a bruise, several planned appearances on various music shows were cancelled due to his condition.
You can watch their performance of “Fantasy” below:
