When the staff had sent the video concerning the little problem in the library where Eden had skillfully managed second-year students, the headmaster didn't expect much at the beginning. Since the staff hadn't mentioned Eden, he just thought that it was just a little something where he needed to congratulate the one who had respected the rules in the library.
But when he watched it and saw that it was Eden, he couldn't be happier than that. It was the perfect opportunity to meet his old best friend once again.
And he also wasn't disappointed when he saw what he did. He had indeed managed the situation too well to be someone else, so he was glad that his old friend was still the same, even after so much time had passed since the day he had killed him.
Will they be friends once again? Or is it just a trick from an illusionnist?
