قسمت 9: رتسو با کمک همکارانش در محل کار، رفتار مشکوک هایدا را بررسی می‌کند.

9

As Retsuko becomes suspicious about Haida, the accounting department's office goes under construction while Haida moves to his own suite. After work, Haida runs into Inui, who suggests he pays more attention to Retsuko. Meanwhile, Retsuko employs help from Kabae, Fenneko, and Ton to break into Haida's office and analyze the data on his computer. Ton suspects that Haida is inflating profits on the company's account book and suggests they find the true data. Retsuko visits Haida to confirm, but he gets angry over her doubting him. When Haida reports to Himuro the next morning, he questions the integrity of their actions, but Himuro convinces him not to waver, as it shows weakness. At dinner, Washimi asks Himuro what he thinks of Retsuko, and he answers that he sees her as obedient rather than rebellious. (Source: Wikipedia)
