Is it a good webtoon?! I'm hesitating bcz rating is low

It is, and it’s not, at the same time. It really depends on the type of stories you like reading. Do you like angst? Can you handle sensitive themes like bullying, self-harm, and trauma? If you can, then you’ll probably like this story. But if you can’t, it’s better to sit this one out, because the characters will definitely piss you off. And honestly, the ML is the only victim in this entire story
