Well, it seems this big sis wasn't having any of it!
Koko took to Twitter on Monday with a very cryptic message about all the "sh*t", writing:

Not on her watch!
K-Pop group Nine Muses was performing at Dong-ah Institute of Media and Arts last week when one of the band members shut down a pervy fan!
The girls performed a number of their hits throughout the show — but during the performance of Ticket, Hyuna noticed an audience member was trying to film up her skirt!
Fortunately, the singer didn't hesitate to tell the fan off as soon as her part was over — immediately glaring at the fan and giving a heads up to her bandmates.
After the song, Hyuna approached the fan from the stage and told him to stop, further exposing the pervert right in front of the audience.
AH-Mazing! We love that the singer stood her ground and shamed that pervy fan-cammer!
