The last night spent with my precious only son. Many memories come flooding back in my mind. While struggling in a motherless family, the two of them supported each other and lived. Today is the last day, and tomorrow my son will leave the nest with a job. In order not to worry her son, Kana tries to send her off with a smile as much as possible. Her loneliness was the same for her son. The two greedily cling to each other. I do not want to leave. The thought goes out of control, and my son does not stop blaming Kana even if she reaches her climax. Kana is attacked by a raging wave of pistons.
