Shizuka had always been kind to Keisuke. It was natural for a mother to build a good relationship with her daughter's boyfriend. It was all for the happiness of her daughter. But those feelings were trampled on by Keisuke's brutality. When Keisuke came to visit while Shizuka was away, he pushed her down and came inside her. Rather than anger or disappointment, what welled up in her was guilt towards her daughter. And distrust for herself for having come against her will. A mother's Kokoro and a woman's instinct. Shizuka was torn between these two emotions. But ever since, Shizuka's body had been waiting to be pushed down again.
