One problem Ciel has after entering university is there was actually someone alive who can beat him at anything. No matter how hard he tried, he just couldn't possibly surpass that person. Until over time, the frustration he had been holding back turned into outright hatred. So Ciel uses some other method to ease his inner thought―hating that person―namely avoidance. What a cruel decision the universe has made for him, Ciel ended up stuck with the person he hated the most for the entire semester.
