I've been dating my current girlfriend for two years. We respect each other, live together, and our bodies are compatible. But the reason I can't marry her… is because of the sadism or petty self-respect lurking deep within me. I went to her house to pay my respects while harboring unresolved feelings, and her mother, Kaori, greeted me… I ended up confessing my negative attitude towards marriage in her absence, but Kaori didn't deny my feelings; she accepted them gently. Annoyed by that casual attitude, I vented my pent-up frustration and sadism on her mother...
