Double Section

Nakai works as an auditor for an insurance company, a profession that routinely earns him hostile glares from his colleagues in the industry. Accustomed to this cold reception, he is pleasantly surprised when his new neighbor greets him with a warm, genuine smile. For a brief moment, Nakai feels a sense of comfort and relief, grateful to have found someone who treats him with basic kindness outside the office. However, that fleeting happiness quickly evaporates when a professional complication arises. Nakai discovers that his friendly neighbor, Takahashi, is actually the salesperson assigned to a problematic client case he must investigate. To make matters worse, beneath that initial neighborly warmth lies a deep-seated resentment; Takahashi despises auditors like Nakai, viewing them as adversaries rather than coworkers. Now bound together by both proximity and professional obligation, the two men find themselves at odds. Their respective roles within the insurance industry clash fundamentally, creating a dynamic as incompatible as oil and water. As Nakai attempts to resolve the issue with the client, he must navigate the growing tension with a neighbor whose job directly conflicts with his own, leaving their complicated relationship hanging in the balance.
