Changmin couldn't not to spy on his sister's bachelorette party. He couldn't just left his sister have fun with her friends in some host club, all alone, without his protecting arms and eyes. It was already hard for him to let her get married to her boyfriend. So when he heard about bachelorette party he almost freaked out (his father too, but after being glared at his wife, he calmed down). He couldn't accept it. His precious sister, going without him, to some club full of males. He heard what they do there, so he was strictly against it, yet no one hears him. And because of this, he was now in that host club, hiding himself behind a pillar, wearing a dress and blond wig and makeup. His eyes were hawking over a small group of girls, especially at one girl, his precious sister.
