Since starting her Instagram account, Sulli had followed aroun 80 close friends and individuals, including boyfriend Dynamic Duo's Choiza, Super Junior's Heechul, and most recently, 'Produce 101's Kim So Hye. 

While some netizens immediately chimed in suspecting that Sulli had broken up with boyfriend Choiza, other netizens noted that the former f(x) member's Instagram had been hacked before, and this could be another hacking case. Others are simply wondering if she is in the process of re-organizing her following list. 

Recently, Sulli had been a topic of controversy for the various content uploaded on her Instagram account.
