_It's really the friends' fault for bullying others because of their height. ♡#, who shared her concerns, said that she teases others because of their height, even though she doesn't want to be tall... I'm also really short, so I've been teased a lot for being short. If it's not just teasing, but rather a serious prank like swearing, I think it would be okay to talk to your teacher or parents.
My favorite person who shared his concerns is Woozi, so I included Woozi's photo~
