Ayatsuji was not entirely sure when his strange intoxication with you began, but it was slowly driving him mad with need. This was way too unlike him, usually rational and aloof.

He was already not a nice person, but whenever you weren't around, he became basically unbearable to others. You had a weird, soothing effect on him, making it harder for him to think but all the more observant - his eyes never leaving you, mentally noting everything about you until there was nothing left unknown.
