This is a post that Karina's former classmate wrote about her after seeing all of the mean comments she was getting:
He wrote, "I was weak in middle school. I was bullied by the boys and slapped in the face under the pretext of homework. I was whispered about and ridiculed during every meal, and Jimin was very nice to me. She had a bright personality and was loved by everyone. Whenever Jimin sat next to me, I felt relieved because I felt I would be harassed less. I became very close with Jimin from the moment I became her desk partner. I always felt good vibes from her, and she was such an upright person that she would say something to me even when I used a mild curse word."
Got this from allkpop but I don't feel like linking to their site today!
