Yura got mean because people constantly built her up to be something she never claimed to be, held her to that standard, then hated her for the image THEY created of her. She didn't just get mean over night for no reason. She couldn't control how she was born/looked any more than she could control the things people said about her. Its super stressful for people to create an image of who you are without actually knowing you as a person. Also those boys were saying gross violating things about her like she was just some object, no wonder she turned so angry. People "liked" her for being pretty, but they never respected her or bothered to get to know her. They always just treated her like a pretty little object to project on.
THANK YOU!!!!
I'm just here thinking way too hard about this when I'm supposed to sleep.
Anyway, in my opinion, none of the characters are right or wrong in their way of doing things, maybe just Jaeha, because he was the one who kept getting hurt like throughout his early stages of life...
Yoseob was, well, abused by both his parents when he was young, none of them showed him much love. Well you can say that his mother was probably not of sane mind when she blamed him for her problems and decided to kill him, and then when he was about to die she would realise it and stop.
What made Yoseob unfeeling? What made him hallucinate people's faces a disgusting monsters? Was it his dad who kept saying that things disgusted him?
On the other hand, we have Yura, who was somehow, born with all the attractiveness that we all had wanted since young. Why does she have that kind of thinking when she's treating people like they're beneath her? Is she desensitised into thinking like that?
Besides, what was the deal with Taeoh? His brother to be fair. What secret schemings did he do with Jaeha....??
One thing I want to find out is how did Yoseob become like this, and also what made Taeoh's brother behave that way towards him?
