On September 19, MBC every1 revealed, "Sunny has decided to leave 'Video Star' to focus on her rehabilitation for her knee injury." Sunny was cast as 'Video Star's maknae MC after SECRET's Hyosung departed from the program, back in May. 

The show has yet to find a replacement MC, and will be testing out special MCs after Sunny's departure. Sunny's final broadcast will be some time in mid-October.
