Some back story to characters:
Felix was a sporty kind and Ciel was a bookish kind. he was dared by friends to go out with her. When they match up. They fall hopelessly. When Ciel learns this, she feels used. Says she hates him. He swears his feelings are real. She is very strong despite be bookish probably more so then Felix. She is one who threatens to not toy with her. She gives his the collar, as that he is to be hers. If he feels that strongly about her. Thus he never take it off, usually. It means the start of there offical relationship.
