After being told by his friend Himori "Your mother is so beautiful, isn't she?", Takuro begins to become conscious of his mother. Seeing her unprotected, such as wrapped in a towel after a shower, reinforces her romantic feelings.

One day, she got angry when she saw her masturbating in her mother's pants.
