Police said in a statement that the 25-year-old had been suffering from “severe depression”. The exact cause of her death was still under investigation.
South Korea has one of the world’s highest rates of suicide which, according to recent government figures, is among the top causes of death for those under 40. Sulli, whose real name was Choi Jin-ri, was known for her outspokenness and drive for women’s rights, for which she had suffered online bullying and harassment.
She debuted in 2009 for f(x), which quickly became one of the top K-pop girl groups worldwide. She suspended her career in 2014 after struggling with cyber-bullying and left the group a year later to focus on acting projects.
According to the Guardian, some of Sulli’s recent Instagram videos show her crying and saying, “I’m not a bad person.”
Sulli was active on social media and recently hosted a TV series where celebrities discussed their experiences with online abuse. According to the Associated Press, she was known for her feminist voice and outspokenness that was rare among female entertainers in deeply conservative South Korea.
Her death sent shockwaves through the K-pop fan community.
“I always adored and respected you for your boldness. All I can say is rest in peace,” a fan commented on Sulli’s Instagram account.
“In heaven, you don’t have to act strong or pretend everything is okay,” another fan said. “I hope you will only think about yourself there.”
