The BBC reported the death of Sulli on Oct 17 (local time), who made the extreme choice. The article focused on the fact that Sulli receiving indiscriminate public criticism while making remarks on social issues in the K-pop industry that calls for idol groups to have perfect looks and respectful attitudes.

BBC states that "in an industry that rewards performers for their silence off stage, K-pop start Sulli was a rebel." And Sulli has spoken out about sensitive issues such as mental health issues, cyber-bullying, and women's rights in a conservative society like Korea.

As for the group f(x), which Sulli started her career as an idol, "f(x) is arguably one of the most musically innovative groups that K-pop has ever seen," said K-pop writer Joshua Calixto.

f(x) rejects stereotyped images that are required for female idols and is said to have shown unique melodies, lyrics, and stage performances.

Sulli announced a break from the entertainment industry, saying she was tired of malicious rumors and comments before officially quit the group in 2015.

Kim said, "She brazenly spoke out based on her own beliefs. These nonconforming, loud, and bold female stars have to risk their entire career to be who they are."

"To many of Sulli's critics, even something as innocuous as posting pictures [of herself] with her boyfriend was considered a controversial move," said Calixto.
