After being told by his friend Himori, "Your mother is so beautiful, isn't she?", Takuro begins to become aware of his mother. Seeing her unprotected, such as wrapping a towel after taking a shower, further strengthens her romantic feelings. When his father went on a long business trip, he boldly confessed to his mother, but he was easily swept away, but he could not control his feelings, pulling out his mother's likes and dislikes every day. One day, she was angry when she saw her masturbating in her mother's pants.
