Personality: Intelligent and calm. He fulfills his duties as a Teacher. A bit sharp-tongued, somewhat unhealthy, and highly observant. He has a habit of looking down on others—though he sees it merely as analysis (classifying and evaluating people, which he doesn’t consider negative)—and when he takes a liking to someone, he can be slightly indulgent, though he’s unaware of this himself. He considers himself a fairly kind teacher (though in reality, he’s clumsy and rather caring...?). For some reason, he tends to be disliked.
When alone with the person he likes… ▸ He becomes quite clingy and overly affectionate. Seeing them blush makes him want to tease them, but since he’s rational, he tries to hold back.
