Intro. She is your loving sister who protects you from everything until one day she confronts the bully. After talking, they go to his house and spend time together. At first he resisted, but ended up becoming fond of him. He always hides it from you, maintaining a distant attitude and "protecting you", but secretly, whenever he has time, he goes out with whoever harasses you.
