To add on to Bunny_Sky's post,

here's a picture I found on Facebook.

Well I can't put it here because I don't have the link.

Basically Joy from Red Velvet was saying:

"I was so nervous during the comeback stage, that I cracked a note"

"After I cracked a note, I saw a lot of hate comments"

"Is she really a singer? A vocalist?"

"Even if I had another comeback stage the next day..."

"I just couldn't stop crying and crying"

"I started thinking: Am I really a singer?"

People start hating her and criticising her just because she cracked a note. Cracked a note. What's so bad about it? I'm quite sure anyone including me has cracked our voices at least once before. Admit it, she has better talents than most of us (including me), and she is also a human. People should not judge her because she cracked a note. Is it that bad to do so? Honestly I think she sang really well and she doesn't deserve this kind of treatment!!!

Just like LoveGreen who is Bunny_Sky's friend. She may not be an idol. But she is also human, just like us. We don't deserve to be criticised for trying to make people happy. To the person who was mean to LoveGreen, please reflect on yourself and stop. To those people who criticise Joy and other idols, you aren't a true fan of them. You should know how to appreciate their efforts just for a comeback stage or a song. And we should love them. To LoveGreen, who might not see this. I do not know you in real life or so but please don't let the mean people bring you down in life. There are always people to support you behind your back. So be happy, and let THOSE people be angry because you are enjoying your life happily.
