We're all only humans. Despite being simply a human being, we're the most dangerous ones on Earth. We have the power to create and destroy. Humans were all born the same except apparently, equality doesn't exist. Gays are judged, there are humans treated as slaves. Abused childs here and there. This world may never have peace, fights are being fought and people die because of them. Because one isn't the same kind as you, because they don't have the same uality as you, they're judged and pushed around like trash. 

Youngjae became a victim. Being looked at differently and treated differently. It wasn't like he deserved it, no one does. He was just a little different, he was still a person. Eventually, Daehyun became his knight. His knight in shining armor.
