Miyanishi-san, who has been married for two years. Thanks to her husband's thriving business, she doesn't have any financial troubles. However, there is one thing that leaves her unsatisfied.

Later, when she mentions the DVD to him, she learns something unexpected about her husband's interests. 'Actually, I want to see you in a video,' he pleads with her to perform.
Finally, overwhelmed by her pent-up frustrations, she makes her decision.
