The Secret of a Secretary

The Nagaoka General detective agency is on the verge of bankruptcy. Nori, the owner's son, does everything he can while his father is away to keep the business afloat, despite his lack of experience with investigating. His biggest challenge is the lazy, perverted ex-cop Aoi-chan, who is their best and only detective.

Nori and Aoi struggle with their newfound love, unable to take the final step to consummate the relationship. Meanwhile, Aoi's childhood friend and rival, Miyasako Yukari, keeps Aoi busy with troublesome jobs that are the agency's only steady income. Elsewhere, Usami, the manager of secretaries at Yukari's company, constantly witnesses Yukari's immoral behavior with the staff and cannot understand why he has feelings for the man.
