Young-Chul explained Nivritti's state of mind to everyone. He said that as she shouted at Bong, she thought that now everyone would start hating her because she insulted their elder, the elder who gave them a chance, because of whom they are now the world-famous boyband.
Him-Chan closed his fists and clenched his jaw in anger. He wanted to shout at her. Was she losing her mind? How could she think like that? They were with her during all that drama. They stood with her. They took her side. They shout at Bong for her and then she goes and pulls that stunt.
Everyone felt exactly like he did but only Jeong-Eun said every word that he wanted to say. He too wanted to call her up like Jeong-Eun and tell her how she could think that they hated her. She didn't even know his feelings about her. He could fight with the world for her.
