Yuka's husband, Yoshinobu, started a transportation company with his best friends Tomohiro and Takeo. Just when they all worked together and things were starting to get on track, Takeo told Yuka that he wanted to quit. The company was barely running with just three people, and if even one person left, it would go bankrupt. Tomohiro's desperate persuasion made Takeo decide not to quit, and Yuka was relieved...or so she thought. But Tomohiro threatened Yuka, claiming that he was grateful for the company's survival.
