A humble life with her beloved husband and son... It was an ordinary happiness, but Fumie decided to protect it for the rest of her life. One day, Takashima, an acquaintance of her husband, comes to visit her house. For a long time, Fumie remembered the old days after seeing Takashima, who had been living in the countryside as a single assignment, and committed adultery with Takashima, even though she knew it was wrong. That night, Fumie strongly seeks out her husband out of guilt for betrayal. However, at that time, there was no way to know that the situation would become even more serious.
