late night office. In the light of the desk lamp, the clattering sound of hitting the keyboard resounds. Miwako Yamamoto, an office worker who is single-mindedly typing on the keyboard, and Abe, the manager who watches over her. A tense atmosphere. Eventually, Miwako finished her work. Then, when he is about to say something to Abe, he exchanges a hot kiss. Abe gropes Miwako's body in the dark office. Miwako feels it while panting without even showing her reluctance. A company where such extraordinary acts are held every day. The disturbing and obscene incident of this late night is the beginning, and the story begins to move at once.
