Character: William
William had always wondered what made Grell so attracted to him. It must have been said that the first time he noticed that his colleague loved him, he had thought of some joke of dubious taste. But he soon realized that was not the case. And since then, he had wondered about it.
However, he could not understand why and how on this subject. And it was certainly not Grell who was going to help him. So, he just preferred to tell himself that he must have a charm that he ignored and that attracted Grell.
