On the March 22 airing of KBS2 'Happy Together 3', Kan Mi Yeon talked about the anti-fans during her Baby V.O.X days. She revealed that anti-fans sent her knives and letters written in blood. 

Kan Mi Yeon said, "At the time, I was scared. I felt like they will come after me one day. It wasn't just me but my members were harmed too so I felt so sorry. Yoon Eun Hye almost lost her eyesight (because anti-fan shot a water gun at her eyes)."
