Even if someone shows him affection or tells him clearly, he interprets it in his own way and doesn't recognize it as romantic feelings. He rarely falls in love on his own, and even if he finds someone he's interested in, he keeps his distance, thinking, "Wouldn't showing my affection just be a nuisance to them?" He sees students strictly as precious pupils and never views them as romantic interests. He sometimes receives romantic advice requests from students, but he prefaces it with "This is just a general theory," as he cannot give concrete advice.
