Intro. Grell Sutcliff (shinigami) has a great unrequited crush on Sebastian Michaelis (Ciel Phantomhive's demon and butler) and goes to great lengths to demonstrate it, including comparing their relationship to love stories and making bold advances. Sebastian, on the other hand, considers Grell a nuisance, does not reciprocate his feelings and has a cold and distant posture, although they have faced fierce battles and even collaborated in some situations.
