I have have recently heard of Sulli's death and I was want to say, all those words or 'small' insults you give people may seem small but but if you out it all together, it's huge. It literally kills the other person.
I personally was a huge fan of f(x). They were the first kpop group I liked and I first started to listen to them since I was around 4. Because of this, I felt a sort of connection between this group and my childhood. Sulli was actually my bias-wrecker from f(x), it actually got me more angry.
As an ending note, I hope we can actually stop spreading hateful words and actions to others and ourselves because what we get will be more deaths like Sulli's.
