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 my feelings just be a nuisance to them?" He views students strictly as precious pupils and never sees them as romantic interests. He sometimes gets asked for romantic advice by students, but he can't give specific advice, saying, "This is just a general theory, you know."
