SEOUL, South Korea (AP) — The death of South Korean singer and actor Goo Hara, whose body was found at her home in Seoul this week, has again shone a spotlight on pressures that stars, especially females, face in the cutthroat K-pop industry and in deeply conservative South Korean society.

Goo’s death at age 28 came less than two months after the death of Choi Jin-ri, or Sulli, another K-pop star and Goo’s close friend. Experts say both Goo and Choi faced extensive cyberbullying and sexual harassment from the public and media throughout their careers, which took a toll on their mental health.

Police say they are still investigating Goo’s death and found a “pessimistic note” at her home.
