The main reason for his reluctance to have close contact with the opposite sex could be traced back to the incident with the middle-aged woman in the sanitarium. That memory haunted his dreams, especially in his teenage years.
Even though the middle-aged woman hadn't done much to him—after all, he had taken control over the woman's body and slammed her head into the wall—the incident had still cast a dark shadow over his growing psyche. This was due to the perverted thoughts that he could read from her mind due to their physical contact.
His youthful soul had been scarred. From that, he had gained the habit of taking several showers a day, and even today, he was famous for his obsession with cleanliness. He felt like he was dirty and needed to clean himself often.
Even though he couldn't stand being near women, for the sake of his work, he had to suppress his feeling of disgust and forced himself to socialize with them throughout the years.
