Meanwhile, Takumi Taniguchi is 35-years-old and unemployed. He did graduate from college, but he spends his days reading books and listening to music. He's not interested in dating or getting married, because he knows he lacks a source of income. He lives with his mother and knows that when she passes away, he can't continue his current lifestyle. Takumi Taniguchi then decides to find a woman who is capable of supporting him financially.
