Double Section

Nakai works as an auditor for an insurance company and is accustomed to facing hostility due to his job. When his neighbor, Takahashi, smiles at him, Nakai is taken aback and pleased. However, this changes when he discovers that Takahashi is the salesperson assigned to his case, as there is an issue involving a client. Complicating matters, Takahashi strongly dislikes auditors like Nakai. The two neighbors now find themselves in a difficult situation, with their professional roles conflicting like oil and water.
