Kanna is 33 years old and has been married for six years, with no children yet. After graduating from university, she started working at a trading company dealing in imported foods. Her husband, whom she dated for two years before marriage, is a client representative. Recently, he was put in charge of a newly opened restaurant, leaving him extremely busy. As a result, the couple's time together has diminished, and emotional distance has grown, making Kanna increasingly aware of loneliness in her marriage. To cope with this emptiness, she became curious about adult videos she found at a secondhand shop. She was deeply shocked by the erotic images of married women around her own age. From that point on, Kanna entered the world of AV, beginning passionate affairs with other men during trips away from her husband.
