It's unfortunate that nothing has changed when it comes to suicide in Korea, let along in the Korean entertainment industry. It's very, very, hard to be a k-pop idol. You are essentially signing away your soul. Some artists will stay with the company for years and never debut. They work you to the bone, they make you starve, they encourage you to get plastic surgery, they eat you alive... Jonghyun left a suicide letter behind explaining his struggles and how he tried so hard to reach out.
As for Sulli, she dealt with years of cyberbullying. Down to how she looked, how much she weighed, etc. Things got worse when she got in a relationship with a man 14 years older than her... He never defended her when Netizens would bully her and pretty much slut shame her while she was with him. Because as a k-pop idol, if it's found out you're dating it can ruin your whole career. Especially if you're a woman. Because you are supposed to uphold this reputation of innocence and purity. I believe they're trying to introduce a bill, called 'Sulli's Law' to prevent cyberbullying in the future... It's really sad, because in the end everyone that bullied her on the internet pretty much has blood on their hands. They aided in her decision. Society killed her. She had attempted in the past, had been in treatment, reached to people prior as well.
And with Goo Hara, that happened to her. She was caught in a scandal with her abusive ex-boyfriend that threatened to release a sex tape of her. She attempted to end her life last May due to all the stress. She apologized to her fans and promised she'd do better. There was no break in between any of this, she pretty much got back to work and was trying to debut in Japan, I believe. The thing is, I ultimately think this time around Sulli had quite a bit of influence in her reasoning to end it. She was not able to make it to Sulli's funeral so she did a live instagram broadcast. She cried and promised Sulli she'll live well... But in the end, I think it really broke her heart and it was one of the final blows for her as Sulli was her best friend. Goo Hara left a suicide note behind expressing how tired she was with life.
It's all so, so unfortunate... Korean culture upsets me so much sometimes.
